Important Product Questions
Does bit diameter alone establish the right anchor hole?
No. Follow the fastener maker’s required diameter, depth and hole-cleaning procedure. A matching diameter does not replace those installation requirements.
What connection should I check before ordering?
Match the actual bit shank supplied to your tool’s holder. Confirm the connection before mounting; do not treat SDS holders and conventional drill chucks as interchangeable.
What if the hole stops clearing dust?
Stop and follow the tool and fastener instructions for clearing the hole. Do not force a clogged bit or continue with damaged carbide.
