Wera 847 Hex Shank Tapping Drill Bit 3.3mm

The Wera 847 HSS Combined Tapping Drill Bit in 2.5mm is designed to drill, tap and deburr in one smooth operation, producing an M3 thread — ideal for lightweight assemblies, electronics housings and smaller fixings where precision is paramount. Manufactured from high speed steel (HSS), the bit's finely-tuned material elasticity ensures it can handle repetitive use without losing performance. The excellent centring properties and low tilt risk make it particularly well-suited to close-tolerance work, keeping every hole straight and true. The ¼" hexagonal shaft ensures maximum power transfer from driver to workpiece, and compatibility with DIN ISO 1173-D 6.3 holders means it integrates seamlessly into existing setups.
