Wera 847 Hex Shank Tapping Drill Bit

The Wera 847 HSS Combined Tapping Drill Bit in 5mm is a highly practical choice for producing M6 threads — one of the most commonly used thread sizes in metalworking, engineering and construction. By combining drilling, tapping and deburring into one step, it significantly reduces the time spent on each fixing point. The HSS construction ensures resilience and longevity, whilst the finely-tuned material elasticity allows the bit to absorb working stresses without compromising accuracy. Clean chip evacuation keeps the cutting zone clear, and the low tilt risk adds confidence
