Torx bit Wera 867/1 BDC TX30x25, diamond-coated tool steel, length 25 mm

Wera Torx bit 867/1 BDC TX30x25 is a 25 mm tool-steel bit with a diamond coating engineered for driven fastening of TX30 Torx screws. The bit is compatible with standard 1/4" hex bit holders and power drivers, providing a compact length for access in confined spaces while maintaining the torsional strength required for repeated assembly and maintenance tasks.

Advantages

The diamond-coated tip increases friction between bit and screw head, reducing cam-out and slipping during torque application. Manufactured from tool steel, the bit offers wear resistance and dimensional stability under repeated load. Its 25 mm length balances reach and control, allowing use with both manual bit holders and powered drivers that accept 1/4" hex bits.

Suitable for

• Assembly of electronic enclosures and mechanical components using TX30 fasteners
• Repair and maintenance work where secure bit-screw engagement is required
• Use with screwdrivers, bit holders, and power tools accepting 1/4" hex bits
• Tasks in confined or recessed fastening locations where a short bit is advantageous

Key specifications

• Bit type: Torx (TX30)
• Length: 25 mm
• Material: tool steel
• Surface: diamond coating on working tip for improved grip
• Drive interface: 1/4" hex-compatible shank
• Intended use: driven fastening of Torx TX30 screws

How to use

Insert the 1/4" hex shank of the bit into a compatible bit holder, screwdriver, or power driver. Position the diamond-coated Torx tip squarely into the TX30 screw head, apply steady axial pressure, and drive the fastener using appropriate torque settings for the application. For powered tools, start at a low speed to ensure correct seating and then increase speed as needed. Withdraw the bit straight out of the screw head to minimize wear on the coating and the screw drive.

Recommendations

Use the bit with correct torque limits to avoid overloading; the diamond coating improves grip but does not increase the bit's torque capacity. Store the bit in a dry place and inspect the tip for wear before critical tasks. Replace the bit if the geometry of the Torx tip is visibly deformed or if slipping occurs repeatedly.
