Broca helicoidal HSS Bosch PointTeQ 1 ud., giro a la derecha, blíster

Bosch HSS Twist Drill Bits PointTeQ are high-speed steel twist drill bits designed for standard drilling tasks. The bits are manufactured to DIN 338 and feature a 135° tip angle with Type N geometry, suitable for general-purpose drilling. A black-oxide coated flute ensures efficient chip removal while the bit body is produced with high elasticity to reduce the risk of breakage, particularly for diameters below 6 mm. The drill bit is intended for right-hand rotation and is supplied in a blister pack as a single piece.

Advantages

The HSS construction provides durability and heat resistance for conventional drilling operations. Black-oxide coating on the flute improves chip evacuation and reduces corrosion. The elastic body design lowers the likelihood of breakage during use, especially on smaller diameters. Conforming to DIN 338 and featuring a 135° tip with Type N geometry ensures predictable centering and reliable performance on a variety of workpieces.

Key specifications

How to use

Secure the workpiece and select the appropriate drill speed for the material. Clamp the Bosch HSS Twist Drill Bit PointTeQ firmly in the drill chuck, ensuring correct alignment for right-hand rotation. Start drilling with moderate pressure, allowing the black-oxide flute to remove chips; withdraw periodically on deeper holes to clear chips and avoid overheating. For best results, use cutting fluid when drilling metals and reduce speed for harder materials.

Recommendations

Use appropriate personal protective equipment, clamp the workpiece securely, and match drill speed and lubrication to the material. For drill bits under 6 mm, the elastic body design reduces breakage risk, but avoid excessive side loads and sudden impacts.
