Twist Drill Bits Bosch HSS PointTeQ 2608577308 5-10mm

HSS Twist Drill Bits PointTeQ by Bosch (MPN 2608577308, EAN 3165140908177) are high-speed steel drill bits with a PointTeQ tip designed for precise and efficient drilling in metals, cast materials and plastics. The bits have a cylindrical shank (shank diameter equals drill diameter), a 135° PointTeQ tip and are manufactured to DIN 338. A black-oxide coated flute improves chip evacuation and the body is produced with increased elasticity to reduce the risk of breakage, especially for diameters below 6 mm.

Advantages

The PointTeQ tip provides fast drilling starts and self-centering to prevent wandering, resulting in higher drilling speed with less heat and wear. The tip geometry remains sharp for sustained durability. Black-oxide flutes support quick chip removal, and the elastic high-speed steel construction lowers breakage risk during use in drill stands and handheld drill drivers.

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 various plastics
• Use in drill stands and handheld drill drivers

Key specifications

• Brand: Bosch
• MPN: 2608577308
• EAN: 3165140908177
• Material: High-speed steel (HSS)
• Tip: PointTeQ, 135°
• Shank: Cylindrical (shank = drill diameter)

How to use

Select the drill bit diameter appropriate for the pilot or clearance hole and mount it securely in a drill stand or drill driver with a cylindrical chuck that accepts the shank size. Start drilling at low speed to establish the self-centering PointTeQ tip, then increase speed according to material and diameter. Use steady pressure and clear chips frequently to avoid overheating. For best results in metals, use appropriate cutting lubricant.

Usage recommendations

For extended tool life and consistent hole quality, use coolant or cutting oil when drilling metals, avoid excessive side loads, and replace bits that show significant wear or chipping. Exercise extra care with diameters under 6 mm to minimize breakage risk.
