Wera 847 Hex Shank Tapping Drill Bit – 847HSS

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. Features and Benefits: • HSS construction for outstanding durability • ¼" hex shaft for very good power transfer • Finely-tuned material elasticity for great durability • Excellent centring properties for accurate drilling • Perfect chip removal for a clean, efficient cut • Low tilt risk for controlled working • Precise return movement Contents: 847 HSS Combined Tap Bit, 2.5mm x 36mm x M3 Specifications: Drill Diameter: 2.5mm Overall Length: 36mm Thread Size: M3 Drive: ¼" Hexagon (DIN ISO 1173-D 6.3) Material: HSS
