Drill Bits Bosch 2608596346 High Durability Precision

The Bosch 2608596346 Installation Drill Bit is a robust HSS drill designed for formwork and general construction tasks. It features a screw-connected drill tip and shank for reduced breakage risk, a tapered flute and offset ends to prevent jamming in moist wood, and an extra-long shank for drilling through multilayer and sandwich materials. The bit is suitable for drilling in wood, plasterboard, light building materials, insulation and various metals, and its cylindrical 13 mm-compatible shank fits drills with a 13 mm chuck. Manufactured to DIN 7490 with a 118° chisel-edge tip, it offers durability and consistent cutting performance.

Advantages

The screw-connected tip and shank improve resistance to breakage and ensure smooth running. The tapered flute and offset ends reduce the risk of jamming in damp wood while maintaining power to cut through embedded nails. The extra-long shank enables versatile drilling in multilayer and sandwich materials. Made of high-speed steel (HSS) and produced to DIN 7490, the bit provides reliable wear resistance and consistent drilling geometry. The cylindrical shank fits standard drills with a 13 mm chuck.

Suitable for

• Formwork and timber construction
• Interior fitting work (plasterboard, boards, beams)
• Plumbing, heating and electrical installation tasks
• Drilling through sandwich materials and multilayer panels with steel or aluminium layers
• Light building materials and insulation

How to use

Secure the cylindrical shank in a drill with a 13 mm chuck and select appropriate speed for the material. Start drilling with light pressure to position the tip, then apply steady, even pressure throughout the cut. For multilayer or sandwich materials, ensure correct alignment and permit the extra-long shank to pass fully through the workpiece. If drilling into materials with embedded metal (nails or plates), use moderate feed to avoid overheating and check bit condition periodically.

Recommendations

Use appropriate personal protective equipment (safety glasses, gloves) and coolant or intermittent feed when drilling metal layers to reduce heat. Inspect the bit regularly for wear and replace if the tip is blunted or if performance declines.
