How to use

Secure the selected bit in the drill chuck and tighten firmly before starting. Mark the drilling position on the workpiece and, where necessary, clamp the material to prevent movement. Start at low speed to establish the hole, then increase speed as appropriate for the wood type and bit diameter. Apply steady axial pressure without forcing; allow the bit to cut and remove chips. Retract periodically for deep holes to clear debris and reduce heat build-up.

Recommendations

Use appropriate personal protective equipment, including safety glasses and hearing protection. For best results, keep bits sharp and free of resin build-up; clean and lightly lubricate when needed. Choose drill speed according to wood hardness and the bit diameter—lower speeds for larger diameters and hardwoods reduce wear and improve hole quality.
