Twist Drill Bit Set Bosch HSS PointTeQ 19 pcs

The Bosch Twist Drill Bit Set HSS PointTeQ (19 pcs) contains high-speed steel drill bits manufactured to DIN 338 with a PointTeQ tip geometry. The self‑centering 135° tip enables quick and accurate drill starts, reduces wandering and increases drilling speed while lowering heat and wear. The bits have a cylindrical shank (shank diameter equals drill diameter), black‑oxide coated flutes for fast chip removal and an elastic body design that reduces the risk of breakage, particularly for diameters below 6 mm. The set is supplied in a hanging box and is intended for use in drill stands and drill drivers.

Advantages

PointTeQ tip ensures self‑centering and reliable starts, increasing drilling speed and reducing heat build‑up. Black‑oxide coated flutes promote fast chip evacuation. Elastic HSS body lowers the likelihood of breakage on smaller diameters. Manufactured to DIN 338 and with a 135° tip angle (Type N), the bits provide consistent durability and precise performance when working with a range of materials.

Suitable for

• Drilling clearance and pilot holes in alloyed and non‑alloyed steels
• Drilling in non‑ferrous metals and cast iron
• Drilling in cast steel and plastics
• Use in drill stands and handheld drill drivers

Key specifications

• Set contents: 19 pieces (Bosch HSS PointTeQ)
• Material: High‑speed steel (HSS)
• Tip geometry: PointTeQ, 135° tip angle, Type N
• Standard: DIN 338
• Shank: Cylindrical (shank diameter = drill diameter)
• Coating: Black‑oxide on flutes
• Intended use: Drill stands and drill drivers

How to use

Secure the required drill bit in the chuck so the cylindrical shank is held firmly. Select an appropriate speed for the material being drilled—lower speeds for harder metals and higher speeds for softer metals and plastics. Use light axial pressure and allow the PointTeQ tip to self‑center; avoid excessive force to reduce heat and wear. Clear chips frequently for continuous cutting performance and cool the workpiece or bit if necessary when drilling harder alloys.

Usage recommendations

For best results, use cutting lubricant when drilling steel or alloyed materials, maintain steady feed pressure, and replace worn bits to preserve drill quality. Store the set in its hanging box to protect the bits and maintain organization.
