Στριφτό τρυπάνι Bosch HSS PointTeQ 3,3 mm

Twist Drill Bit Bosch HSS PointTeQ 3.3mm is a high-speed steel drill bit designed for precise and efficient metal drilling. Made to DIN 338, Type N with a 135° tip, the 3.3 mm bits come in a hanging box of 10 pieces and feature a cylindrical shank suitable for drill stands and drill drivers. The PointTeQ tip design and black-oxide coated flutes support fast chip evacuation and extended tool life.

Advantages

The PointTeQ tip enables faster drilling rates with reduced heat and wear while remaining sharp for continuous durability. The high elasticity of the bit body lowers the risk of breakage, especially for diameters below 6 mm. Black-oxide coated flutes promote quick chip removal and consistent performance. Manufactured to DIN 338 standards, the bits provide predictable geometry and reliable fit in standard chucks.

How to use

Secure the appropriate drill bit in the chuck of a drill stand or drill driver by tightening the cylindrical shank. Select a suitable cutting speed for the metal being drilled and apply steady pressure; the PointTeQ tip design will facilitate fast cutting and chip evacuation. Periodically retract the bit to clear chips if drilling deep holes, and use cutting lubricant where recommended for the workpiece material to reduce heat and extend bit life.

Recommendations

For best results when drilling metals, use appropriate cutting fluid, avoid excessive feed pressure, and match rotational speed to the material. Store bits dry to prevent corrosion of the black-oxide coating and replace worn bits to maintain hole quality.
