Milwaukee Hole Saw

A carbide-tipped masonry bit is the best drill bit to use for bathroom ceramic tile. Regular twist-drill bits can’t cut through the fire-hardened glaze.

But what if you need to bore a 2-inch hole for a plumbing stubout? Contractors typically use expensive hole saws with carbide-grit cutting edges, but there is another way. In most cases, these bath accouterments will be mounted using wall anchors, so getting through the tile is only part of the job. You also need to drill through the substrate behind it in a way that doesn’t cause damage which would prevent the wall anchor from working. They say to measure twice and cut once, but given the consequences of drilling a hole in a tile wall in the wrong place, it’s a good idea to measure three times and drill once.

Standard drill bits don’t work on tile, but not to worry. Ceramic tile can be drilled with a carbide bit, while glass and porcelain call for a diamond-tipped bit.While that sounds expensive, a ¼ inch diamond tipped tip costs under $20, and a carbide bit of the same size can be had for less than $10. When in doubt, buy the diamond bit. It will drill any type of tile.

If you don’t know before now, making circular holes on tiles (ceramic/porcelain) can be difficult. However, our diamond hole saws are suitable for this operation and are also used for making holes in other work pieces including glass, marble, fiberglass, fiber cement board, and terrazzo. They give the best cut when used with water to keep them cool, reduce dust and increase life span.Hole saws are suitable for use when the need for cutting perfectly round holes in your work piece arises. Although their use extends to glass; ceramic; concrete; stone; metals, they are commonly used on woods and plaster. For effective cutting, it is ideally used with a power drill and it’s quite advantageous to use when a hole of about 100 millimeters is to be made.An interesting feature of these hole saws is that the absence of teeth is quite noticeable as they are coated or infused with a diamond which is responsible for their toughness and durability.The usage of hole saws comes with risks especially when they are not well attached to your drill, so knowing how to go about the attachment is important to protect yourself from such risks.

The variable pitch type provides a better cut. when used in wood as the 4/6 tooth configuration allows for better dust and chip extraction while drilling. The fine-tooth type gives a finer cut when used in metal. A cooling liquid is recommended when drilling ferrous metals for both tooth configurations.For your DIY projects, the type of hole saw needed depends largely on the intended use. Luckily, they come in various sizes and are manufactured from different materials to suit your needs.

The available diameters are between the range of ¾ to 6” and you may check our list for your desired size to start making professional holes for your DIY projects.

The carbide hole saws feature tough tungsten carbide tipped teeth that allow for easy cutting action and are also responsible for their remarkable durability. The carbide teeth also enable quick withdrawal of chips and swarf thereby improving its efficiency. Unlike the bi-metal hole saws, carbide hole saws are mainly suitable for cutting through woods, plastics, and fiber cement, not metals. However, there are carbide hole saws designed specifically for metal work as well.Now that you are familiar with the 3 types of hole saws available on the market, it’s necessary to get acquainted with their usage. However, working on different materials may require the usage of different hole saws as previously discussed. Although varying drilling techniques might be required for different hole saws to achieve optimum results, there are some general techniques you should know as a hole saw operator.

As you progress in your DIY project encounter, adding more tools to your toolkit should become a hobby. Some projects require you to use more sophisticated tools. In making holes, of course, you can use drill bits, however, the use of drill bits might not be suitable for some tasks and you may need to go for tools like hole saws.These are versatile hole saws used for making holes on a wide range of work pieces including woods, plastics, aluminum, steel, cast iron, and stainless steel. The serrated teeth are made from an alloy of 8% cobalt and high-speed steel (HSS); a configuration that allows smooth cutting through your work piece and prevents it from heating and wearing out easily during usage, thereby, increasing its durability. These teeth are welded to the body of the hole saw which is typically a softer metal, thus creating a Bi-Metal hole saw.

For remote applications, where neither water no electricity is easily available, it makes sense to use the device with a cordless grinder and pump sprayer. The number of holes one can drill with the setup is limited only by the number of batteries and amount of water one can bring to the work area. Where water and electricity are available it may still make sense to use this setup because it avoids the hassle and tripping hazard posed by electrical cords and hoses.The EZ System consists of a gear box, shaft, and drill attachments that can be connected to a variety of coring bits and certain Metabo angle grinders (corded and cordless).But recent developments in battery and motor technology have led to the development of larger more powerful cordless machines than were available in the past. Among those machines is Metabo’s 9-inch cordless angle grinder which as cordless grinders go is exceptionally large and powerful.GlobalSpec collects only the personal information you have entered above, your device information, and location data.

Hole saws are cutting tools used to make circular holes in a variety of materials. Also referred to as a hole cutter, the tool consists of a cup-shaped metal cylinder with a toothed cutting edge on the open end, usually accompanied with a drill bit to center the hole and keep the saw teeth from slipping. The maximum depth of the hole created is determined by the length of the hole saw body.The saw consists of a metal cylinder, usually steel, mounted on an arbor. The cutting edge either has saw teeth formed in it or industrial diamonds embedded on the teeth. The arbor, also called a mandrel, is responsible for connecting the drill bit to bore and holding the pilot bit. The sloping slots in the cylinder wall help carry the dust out. The kerf (defined as the distance between diverging saw teeth) of the cut is designed to be slightly larger than the diameter of the rest of the hole saw so that it does not get jammed in the hole.

The advantage of hole saws is that they create holes without needing to cut up the core material. This is especially preferable to twist drills or spade drills for relatively large holes (larger than 1 inch). They are also less expensive than boring bits. Disadvantages include the need for a drill that is capable of producing considerable torque at low speed, the tendency to bind if choked with dust, and the core plug can become lodged inside the hole saw.Circle cutters are also adjustable. They have two or three teeth on a platform with a pilot bit. To cut out a hole of any size they need to be adjusted to the proper position. Circle cutters can make larger circles than adjustable hole saws.Adjustable hole saws can make holes of different sizes. It has a flat metal disc with a series of grooves that make progressively wider circles. The saw teeth can be snapped into the grooves that correspond to the size of the planned hole.

Hole saws must adhere to standards to ensure proper design and functionality. Standards include ASME B94.54 and BS 8416, which discuss specifications for hole saws and accessories.

On the clock, Kenny dives deep to discover the practical limits and comparative differences for all kinds of tools. Off the clock, his faith and love for his family are his top priorities, and you’ll typically find him in the kitchen, on his bike (he’s an Ironman), or taking folks out for a day of fishing on Tampa Bay.

However, this design opens up the metal cutting that you want to avoid with the more aggressive saws. The wide range of materials you can cut through makes this an excellent choice as an all-around performer if you don’t want to invest in both styles.

We’ve used these hole saws in more materials than we can count. They cut through all manner of products—some that we wouldn’t have dreamed of using a hole saw on. On other materials, you’d simply burn through several hole saws just to get your hole drilled.

Of course, with fast cutting in materials from metal to wood, any Pro with the need to cut through multiple materials will find these compelling. They serve as great general purpose hole saws that outperform bi-metal and cover materials carbide wood hole saws can’t (or shouldn’t). I’m looking at you, plumbers and remodelers.2022 alone saw the addition of 14 new Hole Dozer carbide-tipped hole saw diameters and 4 new kits. These include a 9pc. Large Diameter Kit, 10pc. Electrician’s Kit, 12pc. Plumber’s Kit, and a 15pc. General Purpose Kit.

People buy carbide teeth hole saws for longevity as much as for getting through “impossible” materials. These hole saws provide users with increased durability and longevity when used on both typical (wood, sheet metal, etc) and extreme (stainless steel, cast iron, cement board, etc) materials.Milwaukee Hole Dozer with Carbide Teeth hole saws feature a unique 3 TPI carbide design. This aggressive tooth geometry allows for fast and aggressive cuts. We find they cut more quickly overall than bi-metal blades but less aggressively than wood-cutting carbide hole saws. You’ll notice a decrease in speed over something like the Milwaukee Carbide Big Hawg when drilling through 2X lumber. The Milwaukee Hole Dozer with Carbide Teeth is primarily a win for metal cutting and materials like fiberglass and cement board. With the ability to tackle stainless steel and anything milder, I’m looking at electricians, HVAC, and MRO Pros as primary targets. The benefits of carbide are well-known to anyone who uses circular saws. Carbide gives a blade or hole saw much more life than a standard bi-metal accessory. It also opens up the ability to cut through materials that would tear up bi-metal quickly. The Milwaukee Hole Dozer with Carbide Teeth can tackle:Retailers and dealers stock both individual hole saws as well as several kits with prices ranging from $12 (single hole saw) to $189.97 (15-piece kit).

Use a spade bit instead of a hole saw to bore up to 1 ½” holes in wood when you don’t need the plug and don’t mind the rough cut edges. Spade bits have two sharp edges with a point in the center. As the bit spins, the edges shave out the wood. Third, use a piece of scrap wood clamped firmly underneath your project. The saw will continue cutting straight through to the backer board, holding the fibers in place as it transitions from one piece to the other. The Forstner bit doesn’t create as much heat as a spade bit. They work well when you need to cut the edge of a board or make an angled hole. However, they can be expensive, and are only typically available in sizes under 3″ in diameter.This can be one of the most frustrating parts about using a hole saw! After you make the perfect circular hole, the wooden plug is stuck inside the blade! The heat created by the cut can cause the wood to bind, making it difficult to remove.My hole saw has a nut that slides over the collar on the back to hold everything in place. Don’t overtighten this nut, or the heat produced can cause it to seize up and make it difficult to remove (I have one that’s permanently stuck!)

Tear out occurs when the back of the workpiece is unsupported, so the wood fibers give way before the cut is complete. This results in a jagged mess of splinters on the back of your project! Here are a few ways to prevent tearout with a hole saw.The first time I opened up the case of my cheap Harbor Freight hole saw set, I was totally confused! All the blades were covered in oil and there were nuts and bolts that fit on some parts and not others. How do you assemble this thing?!?

The other safety concern is heat. Allow your drill to rest during large cuts to prevent overheating, and don’t touch the saw blade until it’s had a chance to cool down. I’ve made the mistake of trying to remove it too soon, and burned my fingers!

Hole saws can be attached to a regular cordless drill or a drill press. There are many types and sizes, which can be used for cutting wood, concrete, tile, and even metal. They’re best used for drilling large diameter holes.

Another method for removing wood from a hole saw is to drill long screws into the wooden plug on both sides of the drill bit. Alternate back and forth between the two screws, slowly driving it in a little further each time. When the tip of the screw hits the bottom of the hole saw, it will start pushing the plug out!

Since an existing hole won’t have any material for the pilot bit, you’ll have to get creative. You could try to cut it with a non-arbored hole saw, but it can be tricky to keep it centered.

An arbored hole saw has a pilot hole drill bit in the center, and a non-arbored hole saw doesn’t. Choosing one over the other comes down to understanding what the pilot drill bit is and how it works.Next, place the collar onto the arbor shaft, and insert the pilot hole drill bit into the collar. Adjust the depth of the drill bit so that it protrudes past the teeth of the saw blade, then tighten the collar set screw with an Allen wrench. If that doesn’t work, you’ll have to disassemble the saw and pop it out from the back. Usually a few good whacks with a hammer on the end of the arbor shaft will suffice! First, the spade bit can be hard to use near the edge of a board. They also don’t make the cleanest hole and tend to tear out. In general, this type of a bit is best for rough construction rather than a fine woodworking project.

For a perfect cut on both sides of the board, cut about halfway through your project, flip it around, and complete the cut from the other side. How do you line it up? Saw into the material until the pilot hole appears on the other side – you can now use this small hole as a guide.

Also, an arbored hole saw is generally easier for a beginner to use because the saw blade won’t skip over the surface of the wood. A non-arbored hole saw is harder to control, so I’d only use them in a drill press with the workpiece clamped down to the table.Cutting a perfect circle in wood doesn’t need to be difficult! There are numerous ways to accomplish this task, depending on the tools you have in your garage. The easiest one to use is a circle shaped saw, named simply, a hole saw.

On larger blades, there will be two holes at the bottom on either side of the center arbor hole. This is for the drive pins, which is a flat plate with two pins sticking up. Insert the drive pins into the holes from the outside. I usually skip this step unless it’s a really big blade, so I can use those holes to easily poke out the wood plug if it gets stuck!

First, choose the right size saw for your project. There should be a number on each one that corresponds to the outside diameter of the circle it will cut.

If you can’t flip the board or access the other side, you can try drilling a relief hole with a spade bit on the edge of the inside of the circle. After maxing out the cut with the hole saw, chisel out the remaining material.Now that you know how to use a hole saw, you can drill holes in just about anything! I hope this guide was helpful, and if you have any questions, feel free to ask them below!After you have your hole saw assembled, it’s time to attach it to your drill. This is just like inserting any other kind of bit, but there are a few things you should know.

Second, tighten the chuck of your drill around the arbor shaft of the hole saw. Be sure it’s not touching the nut (which can cause it to loosen), and check that it’s centered and straight.

I’ll explain the parts of the hole saw as well as some techniques for using them. By the end of this article, you should feel confident wielding this tool on your next project.

A clever tip for enlarging existing holes is to make a plug for it first. Choose a hole saw that’s the same diameter as the smaller hole, and cut a disc out of scrap wood. Switch to the larger hole saw and slide the plug onto the drill bit. The plug will fit into the hole and guide the saw!In this article, I’ll show you how to use a hole saw correctly. Learn how to remove the wood plug from the hole saw and how to avoid tearout, along with other helpful hints!

You can also clamp a scrap of ¼” plywood over the hole, and start your cut on that. The pilot bit will have something to drill through to start the hole, and the teeth embedded in the scrap wood won’t wander once the pilot bit punches through.Insert the arbor shaft and collar through the hole in the center of the saw. Match up the flat sides of the collar with the flat sides of the hole so it seats snugly.

Below is a table of the hardness of various materials. The table uses the standard Knoop Hardness Scale (kg/mm2). The hardest known material is diamond, with a Knoop measurement of 7,000. Tungsten carbide, used in carbide hole saws, is the hardest natural material next to diamond. However, with a measurement of 2,000, tungsten carbide is only 30% as hard as diamond.Diamond hole saws are designed to drill holes in glass, ceramics, porcelain, ceramic and porcelain tile, limestone, slate, marble, granite, stone, and fiberglass. The cutting speed and life of a diamond hole saw are affected by the hardness and abrasiveness of the material plus the drill speed, pressure and lubrication. Experience with a specific material quickly allows a person to determine the optimum drill speed, pressure, and lubrication to obtain the fastest cutting speed with the least effect upon hole saw life and risk of heat fractures or breakage. However, when experience is lacking, it is best to start out with a very slow drill speed, very low pressure and lots of lubrication. This starting point reduces risks to a minimum and extends hole saw life considerably. The hardness and abrasiveness of natural materials, such as stone, vary by type, but they also vary significantly within a specific type. Most stones are not pure – they are mixtures of various types of rock. Granite, for example, contains various combinations of primarily quartz, feldspar, black mica and hornblende. Therefore, a specific stone type such as granite or marble, will vary significantly in hardness and abrasiveness depending upon the exact mineral composition that varies by quarry location. For example, river sand is much less abrasive than quarry sand.

Materials have varying degrees of hardness and abrasiveness. Additionally, specific man-made and natural materials can differ greatly depending upon their exact physical compositions. For example, glass varies in hardness depending upon colour and type, since various metals and minerals are added to achieve the different types and colours. Glass also has differing degrees of “temper” depending upon the specific manufacturing methods used.
