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 Elton Luo

Revainrating 1 out of 5

Bit fell apart after 3 holes

The bit fell apart in the middle of drilling the fourth hole ever. The hardened end separated from the rest of the bit and is now useless.This in addition to the set screw flying out as others have mentioned. Cheap, but you get what you pay for I guess.

Pros
  • DRILLING DEPTH - 9.5" drilling depth
Cons
  • Not suitable for use on vertical surfaces
