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

Ive rated only 2 stars because there were NO instructions from the seller/manufacturer, Ryker. Seems to be an issue, because theres nothing on their website either (in fact, there are complaints about... no instructions. Now, I LOVE puzzles. But not when Im trying to figure out how to put together drill bits. Im new to using hole saw sets... I figured it out eventually (the drill bit must be switched over for the 1 hole (the only hole size that needs to switch, far as I can tell. Why not just put a bit on that size as well so as to not have to mess with the tiny hex wrench? Dumb plan on their part...cheap). Will update once I give them a try... I posted this because I just wasted my time trying to figure out WTH.

So I bought this product - gasp - to drill holes. There are two shanks, one of which is for the larger saws, and one for the smaller saws. The larger one works okay. The smaller one is utter and complete, well, fertilizer. So the way it works is this: the little drill bit has an indentation on it. You stick the drill bit into the shank, and then tighten down a little allen screw to hold the drill bit in. But the allen screw isnt flush to the surface of the shank. This leads to two problems. The first is that the allen screw is softer than a babys bottom. Any pressure at all and it just strips out. The second problem is that you cant slide the saw down over the shank when the allen screw is protruding. So what you end up with is a drill that you can only barely make work, if at all. Its garbage. Utter and complete garbage. I tried to think of ways to get around the problem and I managed to make the holes I needed. Its really not well suited for the kind of plastic I had to drill into - it seemed to actually melt the plastic and bunch it up around the edge. That was easily fixed with a file, so that one is just a lesson learned. But the fact that it has zero durability and is pretty much unfit for purpose is a deal breaker. Im probably going to order a better set and run over this one with a truck. With this kind of durability, no way will it damage the tires.

I had 1 hole to drill. The center bit snapped in half and the actual part i was using (2 inch diameter) bent to the side. Made it very hard to drill the hole. Eventually i got it to work but I would never trust this kit again after it broke on me. Do not buy if you expect it to last.

Tried drilling a hole in 1/4 inch wood. Product fails. Tried with another one. Product fails again. Amazon wants to charge me $7.99 to return this $18.00 purchase just to add insult to injury. Absolutely disgusting quality.

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.

The kit got me through one job I needed it for, thats the only reason I gave it 2 stars. The center drill bit broke out, the set screw that hold it in place wont get tight enough to keep it from spinning without stripping out the allen head. Overall, buy a better quality set if you can.

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.

just what I needed for a project

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 was trying to drill a 1.25 hole into a plastic project box thats about 1.5mm thick. The drill bit started the hole nicely but as the hole saw started to enter into the plastic the saw became dislodged from the screws mandrel/chuck. Then the mandrel became disconnected from the hole saw and jammed in the plastic. I twisted the screw to get it out and then had to use a hammer to get the hole saw and the rest of the 1.25 round plastic out of the project box. This left a nasty edge on the outside of the hole of the project box. I tried sanding the edges but ended up mucking up the exterior of the box. I probably should of used a round metal shaving tool (I dont know what theyre called.)
