Use an insert bit or 1/4 in hex bit that matches the fastener. Check that the locking mechanism fully engages.
Installation & Care
Disconnect tool power before changing accessories. Operate the collar to release the bit and insert its replacement securely.
Keep the socket and collar free of debris. Stop using a holder with a damaged shank or an unreliable lock.

Important Product Questions
Which bits will it hold?
The auto-locking design accepts insert bits and 1/4 in hex bits. Match the driving tip to the fastener separately.
How is the bit removed?
Use the quick-release collar. Its small-profile design is intended for one-handed bit changes with the tool stopped.
Does the holder also help retain the screw?
Its dual magnets increase magnetic transfer and fastener holding. Keep the screw aligned with the bit while starting it.
