Στριφτό τρυπάνι Bosch HSS Twist Drill Bits PointTeQ

The Bosch HSS Twist Drill Bit PointTeQ is designed for precision drilling in metal and wood. Manufactured to DIN 338, this high-speed steel (HSS) twist drill delivers reliable performance with a right-hand rotation and comes in a single-blister package. The bit has a 135° tip and a Type N flute geometry to ensure accurate centring and controlled chip flow.

Advantages

The drill bit body is made with high elasticity to reduce the risk of breakage, particularly for diameters under 6 mm. Its black-oxide coated flute promotes fast chip removal and improved surface interaction during drilling. Compliance with DIN 338 and the 135° tip provide consistent drilling results across metal and wood.

How to use

Select a drill speed appropriate for the material and diameter, clamp the workpiece securely, and use a suitable drill chuck for the HSS twist bit. For metal, use cutting fluid or lubricant to improve chip evacuation and reduce heat. Apply steady pressure and keep the drill aligned; withdraw periodically to clear chips when drilling deeper holes.

Recommendations

For diameters below 6 mm, work at moderate speeds and avoid sudden lateral loads to minimise the small risk of breakage; use lubrication on metals and ensure secure clamping for accurate results.
