Twist Drill Bit Bosch 2608596348 2 cm Diameter 1 pc

The Bosch Installation Drill Bit (diameter 2 cm) is a robust twist drill designed for formwork and general building tasks. It has a screw-connected drill tip and shank end to reduce breakage and ensure smooth operation. The bit features a tapered flute and an offset tip and shank to prevent jamming in moist wood while retaining sufficient cutting power to penetrate embedded nails. An extra-long cylindrical shank provides versatile reach for drilling through multilayer and sandwich building materials. Made from high-speed steel and manufactured to DIN 7490, the bit has a 118° chisel-edge tip and fits drills with a 13 mm chuck.

Advantages

Designed for reduced risk of breakage thanks to the screw-connected drill tip and shank end. Tapered flute and offset geometry minimise jamming in damp or knotty timber while maintaining power to cut through embedded nails. Extra-long cylindrical shank increases reach for multilayer or sandwich materials. HSS construction and DIN 7490 manufacture ensure material strength and consistent cutting performance. Compatible with standard 13 mm chucks for broad drill compatibility.

Suitable for

• Formwork and timber construction
• Interior fitting work (plasterboard, boards, beams)
• Plumbing, heating and electrical installation tasks
• Drilling in light building materials and insulating panels
• Materials with metal layers, such as metal plates or sandwich panels with steel or aluminium

Key specifications

• Diameter: 20 mm
• Material: High-speed steel (HSS)
• Drill tip angle: 118° chisel-edge
• Shank type: Cylindrical, extra-long
• Standards: Manufactured to DIN 7490
• Chuck compatibility: Fits drills with 13 mm chuck

How to use

Secure the drill bit in a drill with a 13 mm chuck, ensuring the shank is clamped firmly. Use steady pressure and moderate drill speed appropriate to the workpiece material; reduce speed when passing through metal layers or embedded nails. For multilayer or sandwich materials, align the bit to the drill axis to avoid wandering and allow the tapered flute to evacuate chips. Withdraw the bit periodically when drilling deep holes to clear debris and prevent overheating.

Usage recommendations

Use appropriate personal protective equipment (safety glasses, gloves) and clamp workpieces where possible. For best results in moist or knotty wood and materials containing metal layers, apply controlled speed and avoid excessive side loading to extend bit life.
