Drill bit Bosch HSS Twist PointTeQ — HSS twist, right-hand, 1 piece, hanging box

Bosch HSS Twist PointTeQ is a high-speed steel twist drill bit designed for right-hand rotation and supplied as a single piece in a hanging box. Manufactured to DIN 338, Type N, with a 135° PointTeQ tip and a cylindrical shank, this drill bit is intended for general purpose drilling in metal and other compatible materials. The PointTeQ tip is self-centering to reduce wandering at drill start, and the geometry delivers a higher drilling rate with reduced heat and wear. A black-oxide coated flute helps fast chip evacuation while the highly elastic HSS body lowers the risk of breakage, especially for diameters below 6 mm.

Advantages

The PointTeQ self-centering tip enables precise starts without the need for additional centering tools, improving accuracy and saving time. The optimized tip and flute geometry increase drilling speed and reduce heat generation and wear on the cutting edges. Black-oxide coating on the flute supports efficient chip removal and corrosion resistance in normal conditions. The cylindrical shank fits standard three-jaw drill chucks and is compatible with drill stands and handheld drill drivers, providing flexible use across typical workshop and maintenance tasks.

Suitable for

• Drilling through steel and cast iron
• General metalworking tasks in workshops
• Repair and maintenance where a single HSS twist bit is required
• Use in drill stands and handheld drill drivers with three-jaw chucks

How to use

Select a drill speed suitable for the work material and diameter, clamp the cylindrical shank securely in a three-jaw chuck or drill stand, and position the self-centering tip at the intended drilling point. Apply steady, moderate pressure while maintaining correct spindle speed to allow the PointTeQ tip and HSS cutting edges to evacuate chips through the flute. For deeper holes, withdraw periodically to clear chips and avoid overheating. Use cutting fluid when drilling harder steels or when prolonged drilling is required to reduce heat build-up and extend bit life.

Usage recommendations

Use lower spindle speeds and cutting fluid for harder steels; avoid excessive pressure which can increase heat and wear. Store the bit in its hanging box to protect the tip. Inspect the tip before reuse and replace the bit if the cutting edges are visibly worn or chipped to maintain drilling precision and safety.
