Screwdriver Bit Wera Torx T25 867/4 IMP DC SB — alloy steel, diamond coated

Wera Torx T25 867/4 IMP DC SB is a single screwdriver bit made from alloy steel with a diamond-coated tip, engineered to improve grip in Torx T25 fasteners. The bit fits standard 1/4" bit holders and drivers, and is suitable for both powered and manual use. Its diamond coating increases friction at the contact surfaces to reduce cam‑out and slippage during tightening and loosening operations, while the alloy steel core provides strength and wear resistance for repeated use.

Advantages

The diamond-coated tip enhances contact security between the bit and Torx T25 recesses, reducing the risk of stripping or rounding fastener heads. The alloy steel construction balances toughness and hardness for reliable torque transfer and extended service life. Compatibility with 1/4" bit systems allows easy integration into common toolsets and powered drivers. The single-bit format simplifies replacement and storage when used in professional or home workshops.

Suitable for

• Assembly and disassembly of electronics, appliances, and mechanical components that use Torx T25 fasteners
• Repair and maintenance tasks in automotive and bicycle applications requiring secure Torx engagement
• General DIY projects and professional workshop use where precise screw driving is needed

Key specifications

• Tip type: Torx T25 with diamond-coated contact surface
• Material: alloy steel core for strength and wear resistance
• Drive size: 1/4" compatible shank
• Finish: diamond coating on tip to increase friction and reduce cam‑out
• Recommended use: compatible with both powered drivers and manual bit holders

How to use

Insert the bit into a 1/4" bit holder or compatible chuck until it locks securely. Align the Torx T25 tip with the fastener recess, apply steady axial pressure, and operate the driver at an appropriate speed and torque setting for the fastener and material. For powered drivers, select a lower speed and torque when starting the fastener to ensure correct seating before increasing power. Remove the bit after use and store in a dry tool case to prevent corrosion.

Usage recommendations

Inspect the tip before use for signs of wear or contamination; a clean, undamaged diamond surface ensures optimal grip. Avoid using the bit at extreme angles that may increase stress and cause slippage. For high‑torque applications, choose a driver with adjustable torque control and consider using impact‑rated bits if repeated high‑torque impacts are expected.
