How to use

Select the appropriate diameter from the set for the required hole size and secure the drill bit in the drill chuck, ensuring it is tightened and centered. Mark the drilling point, clamp the workpiece if necessary, and start drilling at low speed to establish a pilot groove; increase speed gradually according to material and bit diameter. For metal work, use cutting fluid or lubricant when recommended and apply steady pressure without forcing the bit. For wood, clear chips regularly to avoid clogging and overheating. After use, clean the bits of debris and store them in their package to prevent damage.

Usage recommendations

Use protective eyewear and appropriate gloves when drilling. Match drill speed and feed pressure to the material: lower speeds for metals, higher speeds for softwood. Replace bits if they show excessive wear, chipping or reduced cutting performance to maintain hole quality and safety.
