💪 Powerful Koopi Bi-Metal Material Cutter for Efficient Drilling Review

And even comes with an extra center drill bit and Allen key to install if needed. Nice, sharp, and cut through the fiberglass body I was working on.

This is a good solid hole saw. It's not designed for metal, but works well with chipboard. Bonus, it comes with its own mandrel, a spare bit, and a hex wrench for changing the bit.

High quality. Works perfectly. BUT it is NOT 6 1/4 inches. It's only 6 3/32 inches. Not a huge difference, but if for some reason you buy a 6 1/4, expect to get a 6 1/4. It won't work as intended, but I can use it for other projects. Incorrect description information needs to be corrected if they want 5 stars.
