Nice product came timely but no instructions

the bit is not sharp it took an entire day to cut 1/16 plastic about half way through then we used a hammer to try and pop the bit out because it was stuck the the bit split into two pieces

Well worth the purchase

This worked perfectly for cutting the holes in the cornhole games I built. I definitely recommend this product.

Used to cut holes in drywall for ceiling fan boxes. This hole saw worked great! I would purchase again. There is a bit of a learning curve when using this type of hole saw for the first time. Practice on same type of scrap material.

The shank stripped on first use. Returning.

Well it makes holes

Was only sharp to drill hole for one hole in pine. Second hole wouldnt cut.
