Important Product Questions
Does 23 in overall mean 23 in drilling depth?
No. Overall length includes the connection end. Confirm usable length against the required hole depth before selecting the bit.
Can I drill through structural reinforcement?
A bit’s ability to encounter rebar does not authorize cutting structural reinforcement. Stop and confirm an approved hole location before continuing.
How do I choose the right anchor-hole diameter?
This bit is 1-1/2 in diameter. Follow the anchor manufacturer’s drilling instructions rather than choosing a nearby size.
