Drill bit Bosch Formwork and installation 6 mm diameter 400 mm length

Drill bit Bosch Formwork and installation 6 mm diameter 400 mm length is an HSS twist drill with a long shank designed for drilling in formwork and a variety of installation tasks. The 6 mm diameter and 400 mm length provide reach for deep or hard-to-access holes; the tip has a 118° chisel edge and the bit is manufactured to DIN 7490. The drill bit is finished in polished black and complies with the safety standards of the German Timber Trade Association (Berufsgenossenschaft Holz). It is intended for use in drills with a 13 mm chuck and must be used with rotary function only (no impact).

Advantages

The long shank and 400 mm length allow drilling at greater depth and in confined spaces while the HSS material ensures wear resistance and durability. The 118° chisel-edge tip provides precise centring and efficient cutting in wood, light building materials and sandwich materials with steel or aluminium layers. Compliance with DIN 7490 and Berufsgenossenschaft Holz safety standards confirms the manufacturing and safety quality. The 13 mm chuck compatibility makes the bit suitable for common handheld drills.

How to use

Install the 6 mm long-shank HSS drill bit into a drill with a 13 mm chuck and ensure it is secured tightly. Set the drill to rotary mode only; do not use the hammer/impact function. Mark the drilling point, start at low speed to establish the hole and then increase speed as needed while maintaining steady pressure. Withdraw the bit periodically on deep holes to clear chips and avoid overheating.

Usage recommendations

Use appropriate personal protective equipment (eye and hearing protection, gloves) and clamp workpieces where possible. For sandwich materials with metal layers, use steady speed and avoid lateral forces to prolong bit life. Do not use with impact drills.
