## Summary description

Hex bit Wera 840/4 IMP DC SB 5 mm diamond coated is a 5 mm hex screwdriver bit designed for use with impact drivers and power tools. Diamond coating improves grip in screw heads and reduces cam-out.

## Long description

Wera 840/4 IMP DC SB 5 mm diamond coated is a 5 mm hex screwdriver bit engineered for impact drivers and powered screwdrivers. The diamond coating increases surface friction between the bit and hex fastener, reducing the risk of cam‑out and improving torque transfer. Its compact length fits standard bit holders and enables quick changes during assembly or repair tasks.
Advantages
The diamond coating provides enhanced grip in hex recesses, which helps maintain stable contact under high torque and repeated impacts. Designed for use with impact-capable tools, the bit combines durable core material with a hardened tip geometry to resist wear. Its 5 mm hex profile ensures precise fit with corresponding fasteners, while the compact design facilitates access in confined spaces and easy storage in bit sets.
Suitable for
Driving and removing 5 mm hex fasteners with impact drivers and cordless screwdrivers
Professional assembly, maintenance and repair work in workshops and construction
DIY projects requiring strong engagement with hex bolts and screws
Situations that need compact bits for tight spaces and quick bit changes
Key specifications
Bit type: 5 mm hex (HEX)
Coating: diamond-coated tip for improved grip
Compatibility: suitable for impact drivers and powered screwdrivers
Material properties: hardened tip and durable core for wear resistance
Form factor: compact bit length for use in standard bit holders
How to use
Insert the 5 mm hex bit securely into the tool's bit holder or quick-change chuck, ensuring full engagement. Align the bit with the hex recess of the fastener and apply steady pressure while operating the impact driver or powered screwdriver. Use controlled torque settings where available to avoid over‑tightening. After use, inspect the bit tip for wear and replace when the diamond coating or tip geometry shows significant deterioration.
Usage recommendations
Use this diamond-coated hex bit primarily with impact-capable tools for best performance; avoid using with non-impact hand tools where the coating offers limited benefit. Store bits in a protective case to prevent tip damage and keep spare bits available for high-frequency tasks.
