Choose the Correct Fit
Locate existing wiring, pipes and other services before drilling a wall. Confirm that the full bit path is clear.
Secure the three-flat shank in a compatible drill chuck and allow room behind the tool for the long bit.
Installation & Care
After drilling, isolate the tool before attaching the wire to the tip hole. Keep the connection compact and secure.
Pull wire gently to avoid damaging its jacket. Clean the flutes and inspect the tip before storing the bit.

Important Product Questions
How does the bit help pull a wire?
A hole near the tip lets you attach wire after drilling and pull it back through the opening. Disconnect the drill before attaching wire.
Can I drill blindly into a wall cavity?
Check both the intended route and concealed services first. The bit’s reach does not establish that the wall is safe to drill.
Will the three-flat shank fit an impact-driver holder?
Use a compatible drill chuck. A three-flat shank is not a quick-change hex connection, so do not assume it fits an impact-driver holder.
