How to use

Select the appropriate bit from the case for the material and hole diameter you require, then secure it in the drill chuck. For metal and wood, use steady pressure and a suitable rotational speed; for masonry, use a hammer-drill mode or a masonry drill with light forward pressure if the drill supports it. Begin drilling at low speed to establish the hole, then increase speed as appropriate. Remove debris periodically to avoid overheating and to maintain drilling progress. After use, clean the bits if necessary and return them to their organised positions in the case.

Usage recommendations

Use personal protective equipment such as safety glasses and gloves. Match drill speed and feed pressure to the material: lower speeds for metal, moderate speeds for wood, and appropriate hammer mode or impact setting for masonry. Avoid excessive lateral force on the bit to reduce breakage and ensure longer service life; store bits dry to prevent corrosion.
