Wera 848 Hex Shank HSS Drill Bit

The Wera 848 HSS Metal Twist Drill Bit in 8.5mm is a specialist size frequently used for M10 tapping preparation and stepped drilling applications requiring an accurately-sized pilot or clearance hole in metal. The split point tip grips the workpiece immediately, preventing skating across the surface and ensuring every hole is drilled cleanly and accurately from the outset. High speed steel construction with finely-tuned material elasticity means this bit handles the significant torsional forces generated at larger diameters without distortion or premature wear. The viscous-tempered cutting edges hold their sharpness over an extended service life, and the ¼" hex shank provides robust, slip-free engagement with DIN ISO 1173-D 6.3 quick-release holders. Features and Benefits: • HSS with split point — well-suited to M10 tapping preparation • Finely-tuned elasticity resists torsional stress at larger diameters • Viscous-tempered edges for lasting sharpness and cutting performance • ¼" hex shank for strong, secure connection to compatible holders • Excellent concentricity for accurate, consistent hole quality Contents: 848 HSS Metal Twist Drill Bits, 8.5 x 53mm Specifications: Diameter: 8.5mm Overall Length: 53mm Drive: ¼" Hex (DIN ISO 1173-D 6.3)
