Brocas helicoidais HSS Bosch PointTeQ

The Bosch HSS Twist Drill Bit PointTeQ is designed for precision drilling in metal and wood. Manufactured to DIN 338 and featuring a 135° tip, this single HSS twist drill bit offers a highly elastic body to reduce the risk of breakage, particularly for diameters below 6 mm. A black-oxide coated flute ensures faster chip removal and improved drilling performance. The bit is supplied in blister packaging and is intended for right-hand rotation.

Advantages

The HSS construction provides wear resistance and durability while the elastic body lowers the chance of breakage on smaller diameters. The black-oxide coating on the flute promotes efficient chip evacuation. Compliance with DIN 338 and the 135° tip geometry ensure precise hole centring and reliable performance in metal and wood.

How to use

Select a drill speed appropriate for the material and diameter, secure the workpiece, and clamp the drill bit firmly in the chuck. Start drilling with steady pressure and allow the drill to clear chips periodically to avoid overheating. For metal drilling, use cutting fluid or lubricant as needed to extend bit life and improve chip evacuation.

Recommendations

Use lower speeds and cutting fluid when drilling metals, and ensure the bit diameter is suitable for the task; bits below 6 mm benefit from the bit’s elastic design but still require careful handling to minimise breakage.
