Screwdriver Bit Proline 10 mm T25 x 75 mm

Screwdriver Bit Proline 10 mm T25 x 75 mm is a single Torx T25 bit designed for use with bit holders and powered screwdrivers. With a 75 mm overall length and a 10 mm shank diameter, this bit is intended for fastening Torx-head screws in assembly, repair and maintenance work across construction, automotive and general DIY tasks where extra reach and stable connection are needed.

Advantages

The bit is manufactured from high-grade S2 tool steel with a fine-grain structure and hardened to a high hardness range, providing resistance to twisting and reliable durability during repetitive fastening. Its precise Torx T25 profile ensures secure engagement with fasteners, reducing cam-out and wear. The 75 mm length gives improved access to recessed screws while maintaining stable torque transfer when used with compatible holders and powered drivers.

Suitable for

• Assembly of furniture and fixtures requiring Torx T25 fasteners
• Automotive interior and trim fastening where medium reach is required
• Construction and installation tasks with recessed or hard-to-reach screws
• General repair, maintenance and DIY projects using T25 screws

Key specifications

• Tip type: Torx T25
• Overall length: 75 mm
• Shank diameter: 10 mm
• Material: S2 tool steel (hardened)
• Designed for use with: bit holders and powered screwdrivers
• Torque capacity: suitable for medium torque fastening applications

How to use

Insert the 10 mm shank of the Torx T25 bit into a compatible bit holder or the chuck of a powered screwdriver until it locks securely. Align the Torx tip with the screw head and apply steady, axial pressure while operating the driver at an appropriate speed and torque setting for the screw and material. For manual use, fit into a magnetic or quick-change holder to maintain engagement. Inspect the bit tip for wear or rounding before use and replace if engagement is reduced.

Usage recommendations

Use the bit within recommended torque limits for T25 fasteners and avoid excessive side loading. Keep the tip clean and free of debris to prevent slippage. For repeated high-torque or heavy-duty operations consider using impact-rated Torx bits or shorter bits to reduce bending stress. Store in a dry place to avoid corrosion.
