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 Zack Block

Revainrating 5 out of 5

Better than expected

Put this on a Bosch Bulldog (SDS+) using an 18” extension and dry cored through about 32” of brick, CMU, and clay tile that had been thrown together to make an old fireplace. The pilot bit was basically useless for my purpose, but the core bit just kept chewing and spitting out pieces. I was very pleasantly surprised. Definitely would recommend.

Pros
  • This diamond dry core bit is perfect for concrete drilling, with a high level of power and efficiency that gets the job done quickly and effectively
Cons
  • The SDS Plus Pilot Bit Adapter may break or become damaged during use
