Drill Bits Bosch HSS Twist Drill Bits PointTeQ – metal and wood drilling set (Bosch HSS PointTeQ)

Bosch HSS Twist Drill Bits PointTeQ are high-speed steel twist drills intended for general-purpose drilling in metal and wood. The PointTeQ tip improves centering and reduces walking, enabling precise starts and higher drilling speed with reduced heat and wear. These bits feature a cylindrical shank and a black-oxide coated flute for efficient chip removal. Designed to meet DIN 338 and produced with a 135° tip and Type N flute geometry, they are suitable for handheld and stationary drills used in workshops, maintenance and construction tasks.

Advantages

The PointTeQ tip provides reliable self-centering that minimizes wandering at the drill start, which improves accuracy when making pilot and clearance holes. High-speed steel construction maintains cutting performance and durability across a range of materials while the black-oxide flutes support faster chip evacuation. The geometry and manufacturing process deliver a balance of elasticity and strength that reduces the risk of breakage, particularly for smaller diameters, and supports continuous use in both portable drills and drill stands.

Suitable for

• Drilling pilot and clearance holes in alloyed and non-alloyed steel
• Drilling in non-ferrous metals and cast materials
• Drilling in cast iron and plastics
• Use with handheld drills and drill stands for workshop and maintenance tasks

Key specifications

• Material: High-speed steel (HSS)
• Tip design: PointTeQ self-centering tip
• Tip angle: 135°
• Flute type: Type N flute geometry
• Coating: Black-oxide on flutes for improved chip removal
• Shank: Cylindrical shank (shank diameter equal to drill bit diameter)
• Standard: Manufactured to DIN 338

How to use

Secure the appropriate drill bit in the drill chuck ensuring the cylindrical shank seats firmly and the bit is straight. For accurate starts, align the PointTeQ tip with the intended drilling point; the self-centering tip helps prevent wandering. Use appropriate cutting speed and feed for the material being drilled—slower speeds for harder steels, higher speeds for softer non-ferrous metals and plastics. Apply steady pressure without forcing the bit; withdraw occasionally to clear chips if drilling deep holes. For prolonged drilling in metals, use cutting fluid to reduce heat and extend tool life.

Usage recommendations

Choose drill speeds and cutting fluids appropriate to the workpiece material, clamp workpieces securely, and wear eye protection. For best results on metal, use a drill press or steady handheld technique and monitor temperature to avoid overheating the HSS bit.
