Review on πŸ”© Irwin 5026016 Spiral Masonry Tool by Jon Bishop

Revainrating 5 out of 5

ideal for attaching lumber to concrete

I needed to mount my workbench to a concrete block wall. I bought large rock bolts for strength and bought this drill bit to drill through a concrete block wall. I pre-drilled the wood with a regular drill and then switched to this drill to drill through the cinder blocks, which worked well and quickly, just as I expected.

Pros
  • Deep single groove quickly removes dust, increases drill speed and extends drill bit life
Cons
  • Quick instructions
