Wera 848 Hex Shank HSS Drill Bit 3.1mm

The Wera 848 HSS Metal Twist Drill Bit in 3.1mm offers a precise intermediate diameter, making it an excellent choice for tapping preparation, close-tolerance clearance holes, and stepped drilling applications in metal. The split point geometry ensures immediate, accurate bite without slipping, even on curved or uneven surfaces. Constructed from high speed steel with carefully engineered material elasticity, the bit flexes just enough to absorb drilling stress without compromising rigidity or precision. Viscous tempering throughout the body adds toughness for prolonged use, and the ¼" hexagonal shank locks securely into DIN ISO 1173-D 6.3 compatible quick-release holders for efficient power transfer.
