Bosch brocas helicoidales HSS PointTeQ

The Bosch HSS Twist Drill Bit PointTeQ is a high-speed steel drill bit manufactured to DIN 338 for precision drilling in metal and wood. It has a 135° tip and a Type N flute angle, with a black-oxide coated flute for improved chip removal. The bit is produced with a highly elastic body to reduce the risk of breakage, particularly for diameters below 6 mm. The product is supplied in a blister pack and designed for right-hand rotation.

Advantages

The HSS construction provides durability and efficient cutting performance while the black-oxide coating on the flute enhances chip evacuation. The 135° tip and Type N geometry support accurate centring and stable drilling. Increased elasticity in the bit body lowers breakage risk, which is especially beneficial for smaller diameters under 6 mm.

How to use

Secure the drill bit in the chuck of a drill with right-hand rotation. Select an appropriate drilling speed for the material being drilled (lower speeds for harder metals, higher speeds for wood). Use steady, moderate feed pressure and allow the black-oxide coated flute to evacuate chips; periodically withdraw the bit to clear accumulations when drilling deep holes. Ensure correct alignment and clamping of the workpiece before drilling.

Recommendations

For best results, use cutting fluid or lubricant when drilling in metals to extend bit life and improve chip removal. Replace the bit when wear or damage to the tip is visible; avoid excessive side loads to prevent breakage, especially on bits below 6 mm diameter.
