The Wera 847 HSS Combined Tapping Drill Bit in 4.2mm is engineered to drill, tap and deburr in one efficient pass, producing an M5 thread. This versatile size is ideal for medium-duty metalworking tasks, including bracket fabrication, machine assembly and general workshop use. Made from high speed steel (HSS), the bit combines toughness with a finely-tuned material elasticity that resists premature wear. Excellent centring properties mean it engages cleanly without wandering, and the effective chip evacuation design prevents build-up that could otherwise cause damage or inaccuracy. The ¼" hexagonal shaft locks securely into DIN ISO 1173-D 6.3-compatible holders, delivering reliable torque transfer for consistent, repeatable results every time. 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, 4.2mm x 41mm x M5 Specifications: Drill Diameter: 4.2mm Overall Length: 41mm Thread Size: M5 Drive: ¼" Hexagon (DIN ISO 1173-D 6.3) Material: HSS
