Wera 847 Hex Shank Tapping Drill Bit

The Wera 847 HSS Combined Tapping Drill Bit in 8.5mm is the largest in the range, designed to produce M10 threads in a single, efficient operation. Ideal for heavy duty fabrication, structural steelwork and industrial assembly, this size handles the tougher demands of larger thread cutting with ease. Constructed from high speed steel HSS, the bits finely tuned material elasticity ensures it retains its integrity under the greater forces involved in cutting M10 threads. Excellent centring properties keep the bit aligned from the outset, and the efficient chip evacuation design prevents material build up even at this larger diameter. The ¼ hexagonal shaft delivers maximum torque transfer when engaged with DIN ISO 1173 D 6.3 compatible holders, ensuring a controlled and precise result on every cut.
