The Wera 847 HSS Combined Tapping Drill Bit in 6.8mm is built for producing M8 threads — a robust, widely-used thread size across structural, mechanical and industrial applications. Combining drilling, tapping and deburring in one pass, it keeps workflow fast and tool changes to a minimum. Manufactured from high speed steel (HSS), this bit is designed to perform consistently in demanding conditions. The finely-tuned material elasticity provides resistance to fatigue, whilst the precise centring ensures each hole is started accurately. Effective chip removal prevents clogging during deeper cuts, and the secure ¼" hexagonal shaft interface — conforming to DIN ISO 1173-D 6.3 — ensures excellent torque transfer, reducing the effort required to cut clean, accurate M8 threads.
