Screwdriver Bit Torx Wera T30 Diamond Coated, 867/4 IMP DC SB

The Wera T30 Diamond Coated screwdriver bit from the 867/4 IMP DC SB series is a Torx tip bit engineered for improved grip and reduced cam‑out when used with compatible bit holders and power tools. The diamond coating increases friction between the bit and the screw head, helping maintain engagement during assembly and maintenance tasks. The bit conforms to the Torx T30 profile for precise fit in matching fasteners and is intended for repeated use in demanding environments where slip resistance and wear performance matter.

Advantages

The diamond coating provides enhanced bite in the screw recess, decreasing the chance of slipping under torque and improving transfer of driving force. Hardened tip geometry maintains profile accuracy and reduces rounding of screw heads. The bit is compatible with standard 1/4" hex drives and is suitable for use with manual bit holders and powered drivers, offering consistent performance across a range of fastening applications.

Suitable for

• Mechanical assembly and production line fastening
• Equipment maintenance and repair work
• Electronics and appliance servicing where T30 Torx fasteners are used
• Workshop and professional handyman tasks requiring reliable bit engagement

Key specifications

• Drive type: Torx T30 tip
• Coating: diamond grit surface for increased grip
• Shank: standard 1/4" hex for compatibility with common bit holders and drivers
• Material: hardened tool steel for wear resistance and tip retention
• Use case: designed for powered and manual driving applications

How to use

Insert the T30 Torx bit into a compatible 1/4" hex bit holder or directly into the chuck/adapter of a power driver. Ensure the bit seats fully in the fastener recess before applying torque. Use controlled speed and appropriate torque settings on power tools to avoid over‑driving and to protect both the fastener and the bit coating. Inspect the bit tip regularly for wear and replace when the profile shows significant rounding or the diamond coating is compromised.

Usage recommendations

Use the diamond coated Torx bit for tasks where slip resistance is critical. Avoid using the bit on damaged or highly corroded fasteners, and do not apply excessive lateral force. Store bits in a dry environment and replace damaged bits to maintain reliable fastening results.
