Very good for its value very strong and very sharp

### ⭐⭐⭐⭐ Decent hole saw but......
*by G***D on March 7, 2023*

It seems like a well made hole saw with one exception, the chuck bit that connects the hole saw to your drill has the threads in the wrong direction such that when you are drilling out a hole, the hole saw unscrews itself and is basically loose/floating. Have had it fly off and fall to the ground several times. Given the teeth on the hole saw are quite sharp, it does become dangerous, and I actually had my hand cut from it once. I do not know why they didn't provide a better mechanism from keeping the hole saw tight (kind of like how Milwaukee has those two pins that go into hole saw) or make threads reverse threaded such that it would actually tighten itself when you are using the saw.
