The Wera 848 HSS Metal Twist Drill Bit in 5mm is a core workshop size, equally at home in fabrication, maintenance, and precision engineering applications involving steel, aluminium, copper, and similar metals. The split point tip self-centres on contact with the workpiece, delivering clean, accurately positioned holes without drifting. The high speed steel body is engineered with finely-tuned material elasticity, allowing the bit to flex slightly under torsional load without compromising precision — a key factor in extending overall service life. Viscous tempering throughout ensures the cutting edges remain sharp and effective through extended use. The ¼" hex shank provides excellent torque transmission via any DIN ISO 1173-D 6.3 holder. Features and Benefits: • HSS with split point for self-centring, clean-entry drilling • Finely-tuned elasticity reduces stress and extends bit life • Viscous-tempered body for outstanding edge retention • ¼" hex shank for efficient power transfer in quick-release holders • Excellent concentricity ensures accurate hole dimensions Contents: 848 HSS Metal Twist Drill Bits, 5 x 50mm Specifications: Diameter: 5mm Overall Length: 50mm Drive: ¼" Hex (DIN ISO 1173-D 6.3)
