Not Worth the Investment

After I put it to the test, I was highly disappointed with this hole saw. Despite its claims of being bi-metal and variable, it failed to cut through even relatively thin materials and dulled quickly..

Pros
  • Pro: None
Cons
  • Con: Poor cutting ability and quick dulling.

Burns but doesn't cut!

Very disappointed with the quality. Although the teeth appear to be sharp, they only cut through a small portion of the 2x6 before starting to smoke and burn the wood. I had to constantly take off, clean and cool down. I took my time cutting - didn't force it, and there were no nails or screws in the 1-1/2 lumber frame. For comparison, I've used another manufacturer's hole saw for over 40 holes with no problems!

Pros
  • New
Cons
  • Slightly torn
