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 Joe Unruh

Revainrating 2 out of 5

Adaptor shaft: my feedback

The core bit was fine, the SDS adapter shaft is twisted after use indicating that it was not hardened/tempered enough thus when the bit got stuck it twisted the shaft rather than simply stopping the core drill.

Pros
  • The bit works great but you need to apply a lot of pressure for the bit to cut.
Cons
  • Requires well-maintained and sharp pilot bit to function properly
