Twist Drill Bit Bosch 2608597174 2.2 cm Diameter 1 pc

The Bosch Twist Drill Bit 2608597174 (Ø 2.2 cm) is a high-speed steel installation bit designed for robust formwork and general building use. Its screw-connected drill tip and shank reduce the risk of breakage and provide smooth running. The bit's tapered flute and offset ends help prevent jamming in moist wood while maintaining cutting power to penetrate embedded nails. With an extra-long cylindrical shank compatible with 13 mm chucks, the bit is suitable for multilayer and sandwich materials used in construction and interior installation work.

Advantages

The HSS material and DIN 7490 manufacturing standard ensure durability and consistent performance. The screw-connected tip and shank improve strength and reduce breakage. Tapered flute geometry and offset ends minimize jamming in damp timber and allow reliable cutting through metal layers or nails. The extra-long shank increases reach for drilling through multilayer panels and sandwich constructions and fits all drills with a 13 mm chuck.

Suitable for (tasks / use cases)

• Formwork and timber construction
• Drilling boards, planks and beams
• Plasterboard and light building materials
• Insulation panels and sandwich materials (with steel or aluminium layers)
• Interior fitting: plumbing, heating and electrical installation

How to use

Secure the bit in a drill with a 13 mm chuck. Select a steady drilling speed appropriate for HSS and the material being worked—moderate speeds for wood and higher for thin metal layers, avoiding excessive heat. Apply steady pressure and let the bit cut without forcing; retract occasionally to clear chips when drilling deep or through layered materials. For drilling through metal layers or nails, maintain cooling intervals to preserve bit life.

Usage recommendations

For best results, use cutting lubricant or intermittent drilling when penetrating metal layers or embedded nails, and ensure the drill is held perpendicular to the surface. Inspect the bit before use and replace if tip wear or damage is visible.
