Twist Drill Bit Set Bosch HSS PointTeQ 2608577346

Twist Drill Bit Set Bosch HSS PointTeQ 2608577346 — a set of high-speed steel twist drills designed for efficient metal drilling. The PointTeQ tip geometry ensures fast drilling rates, reduced heat and wear, and improved centring for precise starts. These drills are suitable for clearance and pilot holes in alloyed and non-alloyed steel, non-ferrous metals, cast steel, cast iron and plastics. The bits have a cylindrical shank (shank diameter equals drill diameter), a 135° tip angle and are manufactured to DIN 338 standards.

Advantages

The PointTeQ tip prevents wandering at drill start for accurate positioning and faster progress. Increased drilling speed lowers heat generation and wear, while the tip design remains sharp for longer durability. The black-oxide coated flutes promote efficient chip removal. The drills are produced with a highly elastic body to reduce the risk of breakage, particularly for diameters below 6 mm. Compliance with DIN 338 ensures consistent dimensions and quality.

Suitable for

• Drilling clearance and pilot holes in alloyed and non-alloyed steel
• Working with non-ferrous metals (aluminium, brass, copper)
• Drilling cast steel and cast iron
• Drilling plastics and similar materials
• Use in drill stands and handheld drill drivers with cylindrical shank holders

Key specifications

How to use

Select the correct drill diameter for the required clearance or pilot hole. Secure the workpiece and clamp the bit in a compatible drill stand or drill driver with a cylindrical chuck. Start drilling at low speed to allow the PointTeQ tip to self-centre, then increase speed and apply steady, moderate pressure. Use appropriate cutting fluids for steel and alloys to reduce heat and prolong bit life. Remove chips regularly to avoid clogging the flutes.

Usage recommendations

For best results, match drill speed and lubrication to the material: lower speeds and cutting fluid for hard steels, higher speeds for non-ferrous metals and plastics. Replace bits that show significant wear or chipping of the PointTeQ tip to maintain drilling accuracy.
