Milwaukee 49-22-4029 Tool HOLE DOZER Bi-Metal Hole Saw Set (17-Piece) with Case

It’s made of very strong material and drill holes on thick metal plates with ease! It saves me a lot of strength since I don’t have to apply too much heavy pressure.

Definitely practice on scrap wood to understand how these saws handle.

I’ve owned this item before and it worked great. I haven’t used this particular item yet but there seems to be a user error problem that’s making for bad reviews. Let me just say, this is NOT a drill bit. These are hole saws! Using a saw is different then using a drill. When sawing anything you must let the saw do the work instead of forcing the tool into material. When using these hole saws the initial starting of the hole rotate the saw slightly as if you are rolling a ball on the floor in a circle, another example is rotation should be similar to making a dough ball the size of a grapefruit. If you push these saw blades into material using force you WILL get most of the same results most of the bad reviews are talking about. So first rotate slightly making room for the saw teeth to remove material, then gently walk the saws back and forth until you slowly cut through the material. Remember using a hand saw to cut a straight line through a 2x4? Well that’s what is happening with these holes saws with regard to speed. Slow and steady and be smart. Avoid binding, avoid rushing, avoid force! Hope this helps.

The case is cheap and bits don’t stay in place. Bad design but the bits work great
