10-Piece Hole Saw Kit for Wood | Durable Carbon Steel Power Drill Hole Cutter with High Precision Cutting Teeth – Woodworking HCS Hole Saw Kit for Wood, PVC, Plastic, Drywall

Bought these since the set I had was missing a size or two. Used it to cut into some very dense plywood using my drill. It got hot enough to smoke so I had to stop and let it cool a few seconds and use a wire brush to remove the wood that got stuck on the teeth, but after a couple of bites it made it through each time. No warping or damage to teeth after drilling about a dozen holes. I also liked this one because it came with one drill bit for all the hole saws, unlike another set I returned where some of the hole saws only fit the larger drill bit which was too big for my 3/8 drill.

I uses this on sheets of plywood and I struggle to get the 2 and 2 1/4 pieces apart. I have used it on fir and I think maple. It seems like it struggles to cut through a little bit but the maple it actually split some of it on the backside so it looks bad. Luckily I will be covering it in carpet so it wont be seen but I still had to touch it up so the carpet doesnt get cut up. Overall gets the job done but wouldnt buy it for any specialized projects or anything fancy.

Metal is too thin and bends. Used the 2.5 to make a hole in 1 plywood and saw shank bent making the saw teeth not flat against the board. Then the shank ripped through the flat portions that keep the saw from rotating around the shank, becoming useless. I didnt even finish the first hole I was cutting. Next up I tried putting the drill bit in the small arbor to use the 1 hole saw. The set screw sticks out enough to interfere with the locking nut making everything uneven and unbalanced. Totally useless.

There are no directions for first time users. They are not very sharp so took quite a while to get through the wood. Leaves the wood very chipped around the hole. I am not experienced enough to know if thats normal. It came quickly from the seller.

Ive used two sizes so far and no complaints at all. For my occasional use, this was a great purchase.

They provide a drill bit to help you line up. The drill bit works well in the larger mandrel, but does not fit the smaller one. The fastener sticks out too much and this causes the hole saw to skew as it sits on the mandrel <See the picture; note the small black bump on the left side above the threading>. Tightening the collar only helps a small bit. The skew is noticeable and causes oscillations while drilling. I emailed customer support about this, and they did not reply. I was going to bug them again but by then I had missed the return window. Buy your tools from someone else.

I ordered this because I needed to cut a bunch of 2.25-inch holes into a 1/2 plywood. After cutting the first hole the cutout was stuck in the saw. I had to disassemble the whole thing and smash it on the ground to get the wood out of the saw. The next time I tried cutting from the top and then I tried to finish by cutting the other side of the board. Again it got stuck and I still cant get the wood out. After all this effort I ended up going to home depot and got myself a Milwaukee single-hole saw and it cost as much as this entire set, but I was able to cut out 10 more holes in the time it took me to get one drilled with this set. Cheaper is not always better. This saw cannot access the underside or remove the cut wood. It also doesnt seem to cut in a way to create space for the wood to come out. Really I dont understand what this would be good for.

I tried to use the largest 2.5 hole saw to cut through 2 of wooden floor from my crawlspace towards my distribution panel to run some conduit. The hole in the saw which normally has two flats to drive it, rounded out so that it no longer works (see picture for comparison of good drive hole vs bad). As the largest hole saw in the pack this is the most torque demanding. However the saw was evidently insufficiently hardened for the task, hence the 1-star for durability.

You get what you pay for. Drill bit broke, set screw stripped, don’t plan on going through anything other than a wet paper bag with these.

Dont count on this to cut a hole in a precise location, or to have the hole cleanly cut, as the drill bit doesnt necessarily center the round cutting blade - if you can get the round cutting blade to even seat upon that bit at all. The first hole blade I tried to use wouldnt seat because its cutout hole was off center. It is unusable. The second one I tried could be bolted on, but wouldnt turn evenly in the drill. Instead it wobbled back and forth even when it was properly tightened in a drill that could handle every other bit its ever taken. But that was sufficient for cutting the hole I needed at that moment. I dont know if any of the other hole bits will work for my purposes. This was certainly inexpensive - and if your expectations are low, it may work for you. Its definitely NOT High Precision (as advertised.) For a birdhouse hole, a bird probably wont care if its off-kilter. But if youre cutting a hole where it matters, you might want to spend a little more and go with something better.
