Twist drill bit Bosch HSS PointTeQ — right-hand rotation, single piece (blister)

Bosch HSS Twist Drill Bit PointTeQ is a single high-speed steel (HSS) twist drill in blister packaging, designed for right-hand rotation drilling. The bit conforms to DIN 338 and has a Type N flute geometry with a 135° point angle. Black-oxide coated flutes improve chip evacuation, and the bit body is manufactured to be highly elastic to reduce the risk of breakage, particularly for diameters below 6 mm. The compact blister makes the bit suitable for one-off tasks, replacements or as a spare in a toolkit.

Advantages

The HSS material ensures hardness and wear resistance for standard drilling applications. The 135° point provides stable centring and reduced walking on start. Black-oxide coated flutes enable faster chip removal and help maintain drilling efficiency. The elastic bit body reduces breakage risk during use, especially for smaller diameters. Compliance with DIN 338 guarantees consistent dimensions and performance.

How to use

Secure the drill bit in a compatible chuck and set the drill for right-hand rotation. Select a suitable speed for the material being drilled and, if necessary, use cutting fluid to reduce heat and improve chip extraction. Begin drilling with steady pressure, allowing the bit to cut while avoiding excessive force. Clear chips regularly and withdraw the bit periodically for deep holes to help chip removal and cooling.

Recommendations

Use appropriate personal protective equipment (safety glasses and gloves) and match the drill speed to the material. For best results on harder metals, apply cutting lubricant and avoid side loads that could cause breakage, especially on bits below 6 mm diameter.
