Review on 9.5" Diamond Dry Core Bit For Brick And Block With SDS Plus Pilot Bit Adapter, 5/8"-11 Arbor And 9.5" Drilling Depth - Perfect For Concrete Drilling by Bill Snyder

Revainrating 1 out of 5

A few problems with the product

The drill bits it way to short. It makes it really hard to start the hole. Also the set screw keeps coming loose no matter how hard I tighten it. The hole saw cuts good but binds a lot the further the drill penetrates.
