Advantages

This 3.5 mm drill bit delivers consistent hole size and straightness due to its precisely ground tip and balanced geometry. Its 70 mm length provides a good combination of reach and rigidity, reducing flex during operation.

How to use

Secure the drill bit in a compatible drill chuck, ensuring it is centered and tightened. Select an appropriate drilling speed based on the material: lower speeds for metals and higher speeds for wood and plastics. Use steady, moderate pressure and allow the bit to cut without forcing; withdraw periodically to clear chips when drilling deeper holes. For increased accuracy, mark the drilling point and, if necessary, create a small starter indent with a centre punch or pilot point.

Recommendations

Wear appropriate eye protection and follow machine safety guidelines. For best results, match drilling speed and feed rate to the material being drilled and replace the bit when signs of wear or bluntness affect performance.
