Screwdriver Bit Wera 847 HSS

The Wera 847 HSS screwdriver bit is a high-quality combination tapping drill bit made from high-speed steel (HSS) for drilling, tapping and deburring. The bit is designed for professional use, providing precise centring, efficient chip removal and low tilt risk. It has a hexagonal 1/4" drive shaft compatible with holders to DIN ISO 1173-D 6.3 and is supplied singly for easy replacement or addition to a toolkit.

Advantages

Manufactured from HSS for good wear resistance and long service life. Optimised material elasticity improves durability while maintaining cutting performance. Very good centring properties and effective chip evacuation reduce binding and improve operation quality. Hexagonal 1/4" shaft ensures reliable power transfer and compatibility with standard holders.

Suitable for

• Drilling small holes in metal and other materials
• Tapping and thread-starting operations
• Deburring edges after machining
• Use with 1/4" hex drivers and bit holders compliant with DIN ISO 1173-D 6.3
