Wera 848 Hex Shank HSS Drill Bit

The Wera 848 HSS Metal Twist Drill Bit in 4.1mm provides a precise intermediate diameter particularly useful for close-tolerance fitting, stepped hole enlargement, and tapping preparation where standard 4mm is marginally undersized. The split point tip grips the workpiece immediately, ensuring clean, accurate drilling without centre-punching in most situations.

High speed steel construction with finely-tuned material elasticity means the bit handles drilling stress efficiently, reducing the risk of snap or distortion under load. The viscous-tempered body maintains sharpness and structural integrity over a long working life. Fitted with a ¼" hex shank, this bit connects securely to DIN ISO 1173-D 6.3 quick-release holders for efficient power transmission.

Features and Benefits:
• HSS with split point for immediate, accurate bite
• Finely-tuned material elasticity for resilience and longevity
• Viscous-tempered steel retains cutting edge under repeated use
• ¼" hex shank for firm engagement with quick-release holders
• Excellent concentricity for consistently accurate results
