Screwdriver Bit Wiha 33721 — Torx T10, Length 90 mm, 1 pc

Single Torx screwdriver bit Wiha 33721 — Torx T10, Length 90 mm, 1 pc is a hardened, precision machined bit designed for use with standard bit holders and screwdriver handles. The 90 mm length provides extra reach for recessed fasteners and improved access in confined spaces while the compact, lightweight construction (approx. 11.7 g) keeps handling comfortable for repair, assembly and maintenance tasks in electronics, automotive and general DIY work.

Advantages

The bit is manufactured from hardened tool steel for consistent tip geometry and long life under repeated use. Contrasting laser marking allows quick recognition of the Torx T10 profile, reducing time spent selecting the correct bit. Its engineered tip and tight tolerances deliver stable engagement with Torx fasteners and improved rotation characteristics to minimise cam-out and wear.

Suitable for

• Electronic device assembly and repair
• Automotive interior and small part fastening
• General household and DIY maintenance
• Workshop and trade applications requiring precise Torx T10 fastening

Key specifications

• Profile: Torx T10
• Length: 90 mm overall
• Material: hardened tool steel with precision tip geometry
• Finish: contrasting laser marking for fast profile identification
• Weight: approximately 11.7 g
• Compatibility: fits standard 1/4" bit holders and screwdriver handles

How to use

Insert the bit firmly into a compatible bit holder or screwdriver handle until it is fully seated. Position the Torx T10 tip into the fastener recess and apply steady axial pressure while turning to engage the head. Use the 90 mm length for improved reach to recessed or hard-to-access screws. Inspect the tip for wear before critical tasks and replace the bit if tip deformation or rounding is visible to avoid damaging fasteners.

Usage recommendations

For extended tool life and optimal fastening results, use the bit with a correctly sized Torx T10 driver and avoid excessive torque beyond the fastener rating. Store the bit in a dry, organised holder to protect the tip geometry and the laser marking.
