Insert the chuck key into the chuck and turn it counterclockwise to loosen the bit. Gently pull the bit out once it’s loose.
Keyless Chuck
Grip the chuck with one hand and turn the front part of the chuck counterclockwise with the other hand. Remove the bit once it’s loosened.
SDS-plus Chuck
Pull back the locking sleeve on the chuck and slide the bit out.
Inserting the New Bit
