Precations on use
When inserting screw-free center drills, be sure to rotate the center drill one turn clockwise while pushing it in. To detach, rotate counter-clockwise while pulling out.
Screw-free center drills may also be used with previous shanks, but note that old-type center drills cannot be used with screw-free shanks.
Both old and new-style bodies (replacement bits) can be used.
Gloves must always be worn to prevent injury to hands or fingers when pulling out screw-free center drills.
Risk of injury to hands when removing debris by extracting center drills. Always detach the body before removing debris.
