Product Overview

  • Hole Saw drill through wood, plastic, aluminum, metal
  • Bi-metal construction for increased wear resistance
  • Lifetime limited warranty against saw tooth breakage
Use the Milwaukee 4 in. Bi-Metal Hole Saw to cut holes in a variety of materials. The steel hole saw can drill almost 2 in. D. Milwaukee Ice Hardened products utilize a proprietary cryogenic hardening process that improves upon traditional heat treat processes. Unlike surface coatings that wear away, cryogenics harden to the core by minimizing soft metal (austenite) and creating more hard metal (Marten site). The result is a product that is more consistently hard throughout, resulting in life up to 50% longer than the competition.
  • 1/2 in. chuck size
  • High-speed steel construction
  • 4 in. Dia
  • 1-51/64 in. drilling depth

Questions & Answers

can this product cut through 2'' wood

can this product cut through 2'' wood
Asked by: kevin
Yes you can but it better not to do it at once. You need to cut about an inch deep, then with a chisel break off the 1 inch disk you made, then continue cutting the remaining with the hole tool. I hope that answers your question.

I purchased this tool a week ago and I have been pleased with how well it performs. I like the larger slots in the sides of the hole saw they are very useful when trying to remove the circle of wood that was just cut out of the board. Some of the hole saws I have used in the past have small slots and do not go high enough on the side of the saw to allow me to remove a circle of a "2 by" board. The size and position of the slots on this hole saw allows me to insert a screwdriver to pry the circle out of the saw. A word of warning: be careful when the saw initially makes contact with the wood since the saw is so large it will try to spin your drill motor if you do not have a firm grip on it. If you have a side handle for your drill motor I recommend installing it when using this hole saw.

Rated 5 out of 5 by from Great Hole Saw I've been using this hole saw to make a wine bottle holder. Of course, I'm not an expert, so I've made plenty of test runs using everything from MDF to poplar to common wood to pine. The cuts come out the same every time, although the real woods will require a little sanding afterward. (The MDF is smooth.) I've cut through various widths (1/4" to 1") without issue, and I've done it all with a drill press. I cannot attest for how this will work with a handheld drill, although I would think a steady hand well clamped wood would produce similar results. Note that, unless you already have one, you'll need to get the chuck for this too (around $15). The chuck fits all the Milwaukee hole saws from around 2"-6", so it's a one time purchase. (I have two other Milwaukee hole saws in different sizes and all use the same chuck.) If you need holes drilled, you've found the right tool. If you have to go smaller than 2" or so, get a forstner bit instead. For larger projects, this is your part.

First off, Milwaukee needs to put some instructions on the packaging, see below (and pics) on how to use this hole saw. I bought the 4 1/8" hole saw to bore holes for dryer, bathroom & kitchen 4" exhaust vents. I thought the 4" would work, but the plastic vent shaft is actually a hair over 4" so a 4" hole saw is really too small. It's actually a tight fit even with the 4 1/8” hole saw. If you have a job that will require you to attach the venting hose as well as a hose clamp that you need to put on first, and then install it, like for a soffit, then you'll need a larger hole saw. I was able to do the 3 holes I needed with the 4 1/8", but I should mention that I had access to the soffit from the inside because the ceiling drywall in my new addition wasn't up yet. In the older part of my house I wanted to add a soffit vent to a bathroom, but ended up having to go 10' out to the side eve because the soffits where not accessible to tighten the hose clamp. When drilling vinyl siding you'll have to move the inner drill bit out to about 1" past the outer hole saw to keep the saw from wondering. At first I couldn't find the set screw as my older model had it closer to the end, then I realized that it's behind the tightening nut, so loosen that all the way first, then push the 2 pin collar towards the tip to access Allen screw. It takes an 1/8" (or 3mm in a pinch) Allen wrench. I found the large 1 1/8" nut really only needs to be tightened by hand as the pins really drive the saw & there is a rubber O ring between the two parts to keep enough friction on the collar. If you will be using this every day & not changing the size of the saw, then go ahead and wrench it down, but I'm constantly using different sizes and rather not have to carry a large 1 1/8" wrench or adjustable wrench around. So thank you Milwaukee for adding the rubber "O" ring. The hole saw did a great job of quickly digging right thru double thickness 3/4" 60 year old plywood which was VERY hard. The plug that was left in the saw was easy to remove with a flat head screwdriver as the access holes around the side of the saw are well placed. There are also two 5/16" holes at the back of the saw if you have a really stubborn plug & need to use a punch, dowel, bolt, head of a nail or small blade screwdriver to get it out.

Rated 3 out of 5 by from fair on wood For a hand drill (which is hard to controll rpm exactly) I dont think it is as good of a value as the carbide coated blades such as darerdevil carbide by bosch. I bought this blade at 1 1/8 inch and bored several holes in 3/4 inch lumber. It was smoking (burning) by the time i finished each hole. Perhaps it would be better at slower speed, but on a VSR hand drill it is difficult to conrol speed. I found it is necessary to clamp my board, and my dewalt 20V maxed out on torque at highest clutch setting. Can’t use this on concrete either I dont think. If carbide had been available I would have gotten it. It may be fine on a drill press. I have had better results with carbide blades of similar size.

I purchased this Milwaukee hole saw to run a hood range exhaust from the kitchen to the outside of the house. This hole saw performed flawlessly. It cut through the drywall and wood as expected. Additionally, I used it to cut through the siding on the outside of my house. (For the record, I did this with the drill spinning in reverse.) It made a beautiful clean cut in that as well. I couldn't have been happier with this product which is why I always, and only, purchase Milwaukee hole saws.

Used this to drill 2 x 3-⅝ in holes into some heavy duty fiber board (not medium duty/mdf). Well over an inch deep. What I found was I could not run my drill forward with HDFB. It would easily catch and jump. But if I run it in reverse it would cut just as well, but not jump. The result was 2 cup-holders drilled into my home-made arcade machine.
