How to use

Select the bit that matches the screw head or drill diameter required. Insert the chosen screwdriver bit into the quick-change bit holder or the drill chuck, ensuring a secure fit. For deep-set screws, use the 50 mm bits to reach recessed heads. When drilling masonry, use the HSS stone drill bits with carbide tips at appropriate drill speed and with steady pressure. Observe the correct rotation direction (right-hand) and secure the workpiece before operating the drill.

Usage recommendations

Wear appropriate eye protection and, when drilling masonry, use dust extraction or a mask. Match bit type and size to the fastener or material, avoid excessive side pressure on bits, and replace worn bits to maintain performance and safety.
