Bosch HSS Twist Drill Bits PointTeQ

The Bosch HSS Twist Drill Bit PointTeQ is designed for precise drilling in metal and manufactured to DIN 338. The bit features a 135° tip and a Type N flute geometry, delivered in a blister pack for safe handling. Its black-oxide coated flute improves chip evacuation while the high-elasticity body reduces the risk of breakage, particularly for diameters below 6 mm.

Advantages

The black-oxide coated flute enables faster chip removal and helps maintain a cleaner hole. The high-elasticity HSS body lowers the probability of bit fracture during standard metal drilling. Conformance to DIN 338 and a 135° tip ensure reliable centering and consistent hole quality across metalworking tasks.

How to use

Secure the workpiece and select a suitable drill speed for the metal being drilled. Mount the Bosch HSS PointTeQ drill bit in the chuck, ensuring it is centered and tightened. Start drilling with steady pressure and allow the black-oxide flute to clear chips; withdraw occasionally to remove accumulated chips when drilling deeper holes. Use cutting fluid when drilling harder metals or for prolonged drilling to extend bit life.

Recommendations

For diameters below 6 mm the highly elastic design reduces breakage risk; nevertheless, use appropriate speeds, steady feed and lubrication as required by the material to achieve optimal hole quality and tool life.
