Punta elicoidale Bosch 2608597167 2,2 cm diametro 1 pezzo

The Bosch Twist Drill Bit 2608597167 (2.2 cm diameter, 1 pc) is a high-speed steel (HSS) installation drill bit designed for robust formwork and general building work. Manufactured to DIN 7490, the bit features a screw-connected drill tip and shank to reduce breakage risk, a tapered flute and offset geometry to avoid jamming in moist wood, and sufficient cutting strength to pass through embedded nails. An extra-long cylindrical shank (for 13 mm chucks) provides extended reach for drilling multilayer and sandwich building materials used in construction trades and interior installations.

Advantages

The screw-connected tip and shank construction improves running smoothness and reduces the chance of breakage under load. The tapered flute and offset ends minimise jamming when working in damp timber, while the HSS material and 118° chisel-point tip deliver reliable cutting performance, including the ability to cut through some embedded metal. The cylindrical shank is compatible with all drills that accept a 13 mm chuck, and the extra-long length enables drilling through thick or layered materials.

Suitable for

• Formwork and general carpentry (boards, planks, beams)
• Interior fitting work, plumbing, heating and electrical installation
• Drilling plasterboard, light building materials and insulation
• Penetrating metal layers such as metal plates, sandwich materials with steel or aluminium

How to use

Fit the cylindrical shank securely into a drill with a 13 mm chuck. Start drilling at low speed to establish the hole and then increase speed as appropriate for the material. Apply steady, even pressure; avoid forcing the bit to reduce the risk of breakage. For multilayer or sandwich materials, use the extra reach of the long shank to maintain a straight drilling path. Clear chips periodically to maintain flute performance, especially when drilling damp wood or mixed materials.

Recommendations

Use appropriate personal protective equipment (eye and hearing protection, gloves) and select drill speed according to the material. When encountering embedded nails or metal layers, reduce speed and use steady pressure to prevent overheating. Inspect the bit before use and replace if tip damage or excessive wear is visible.
