Milwaukee 49-22-4025 13-Piece General Purpose Hole Saw Kit - Premium Hole Dozer Set for Wood, Metal & Plastic - Perfect for DIY Projects, Construction & Electrical Work

These work really well on sheet metal & thinner metal. Thicker metal you have to go slow & use oil but it will work up to 1/4”Honestly for what it is it works. I will say the Craftsmanship is a bit spotty for the $80 and made in the USA I find it hard to complain (it's a tool it ain't gonna stay perfect unless it's sitting in a drawer).I'm giving this kit five stars because the quality is there and as I pointed out in the caption, it's the best way to spend money on hole saws; buying a kit (unless you have just one project calling for only one or two sizes).Like one reviewer noted, more hole saws don't necessarily fit in the plastic box, but some WILL fit. The "large arbor" saws can be stacked one additional saw inside the other. Also, a couple of the "large arbor" saws can be moved and stacked and then a couple additional of the taller, "small arbor" saws can be placed in the spots vacated by the "large arbor" saws. (I know that sounds complicated, but once you have the box in front of you it will be obvious what I'm talking about.) The plastic box itself is a good one, very sturdy, heavy plastic with a strong latch.My main criticism is that a couple of sizes that you might think should be included are not; for example, the 1" size and the 1 1/4" are not included. The kit goes from 7/8" to 1 1/8" to 1 3/8".....seems a bit (no pun intended) odd. I added a size 1" and a size 1 1/4" from Home Depot's tool department (and they do fit inside with the rest of the kit).As far as performance, I have used a couple of the saws in my drill press and they do drill holes. It's important to not try to drill the hole too quickly, frequently lift the saw out of the hole for a several second "cool down" (don't let it smoke!) and then continue. Also, run your drill at the correct speed. My drill press speed table calls for 500 rpm for most of these saws in soft wood (the speed will vary depending upon what you're drilling). 500 rpm is SLOW and that may be why some people are reporting less than perfect results. But I have found that these saws cut very clean entries with no "tear out". Use a sacrificial backer for the exit, or turn the work upside down for the finish cut; either method will work.One thing that I don't like is that there is a heavy coat of protective white paint on these saws. It makes sense to protect them with paint, but the bad news is that until the paint on the saw teeth wears off, it will melt and make something of a mess of the saw teeth. The heat generated by cutting makes the paint soften, melt and then it embeds fine debris from the cutting. A small soft brass brush is handy to clean up the saws.First time I've bought a set of hole saws in 30 years. I'm taken aback by the quality of these Milwaukee Hole Dozers. And not in a good way. These seem to be made from a flat sheet of tool steel that is then roughly formed into a circle and welded at the seam. This has the consequence of leaving an imprecise hole due to the runout. The first pic of a 1.5" saw shows the variation. It you need to drill a hole in a 2x4 or plywood that is roughly 1.5" these may suit you fine. I need to drill into 1/4" steel and need a closer fit to the advertised size. The runout requires more down force as well as the kerf width is a combination of the MIN and MAX. Of the 9 saws in my set, 5 of them have this runout issue and I'll be returning the set. Wondering if I had a set of fakes I went to the local big box store to compare. Sadly, the Hole Dozer hole saws there suffer the same issue. My 30 year old Disston saws are one piece and very precise. No welded seams. Looking at the Lennox and Disston sets sold today they appear welded as well so I don't know the answer for finding more precision. The search continues.The biggest issue on these is quality control. The 1 3/8” hole saw had a bad weld, resulting in one tooth being pushed out at least 1/16”. You add some wobble while on the arbor and my 1 3/8” hole saw was making 1 1/2” holes even with the aid of a drill press. The other hole saws seemed better but still not great. I really needed the 1 3/8” to be reasonable accurate so I returned it back to Amazon. Thanks to Amazon with the great rerun policy.I ended up getting the Lenox 13pc set for $90, about $20-$30 more. But this set had perfect welds and there was no wobble when on the arbor. This resulted in much better and more accurate cuts.If you need rough cuts in 2x4s then this set is fine but I would pay the extra few dollars for much better quality and accuracy.Had a new comparable Bosch set that I could not get to work, I don’t have a lot of strength in my hands (arthritis). Went online and found a nice demo on this same Milwaukee set. Video made it look really easy. (Bosch customer service said they did not have an instructional video.) I even had a handyman try out my new Bosch set and *he* had trouble changing the saws! (As he is younger and doesn’t have arthritis, I figured he could learn to deal with it, so I gave it to him.)When this Milwaukee arrived, it worked easily, just like the guy’s in the video. (And the two flat sides of the device that holds the saw blade makes it so much easier to grip. (The Bosch was round.) I'm very happy. (If you want to see the video that sold me, it’s on YouTube under “Milwaukee Quick Change Arbor and Hole Saw Kit Demonstration” (Sparky Channel).I did and I indeed saw the top reviews blast this set for the exact same reasons I returned these as soon as I opened the box. Hate to see Milwaukee go this route but here we are with this offering. Best part is the box handle is designed so poorly that it pushes the door open when carrying it because the poor design. Literally can't swing all the way straight because it's molded right against the door instead of midway so the handle will never go straight up and you carry it at an angle with it constantly pressing against the door and creasing it open. So shoddy I am hoping this is some fake BS with Milwaukee's name slapped on it but it looks genuine. Knee deep into a ecosystem feeling like maybe up to my neck now if this is an indicator of where Milwaukee is heading in quality lol.
