Screwdriver Bit KS Tools 911.5147 Torx T55 30mm Hexagonal

The KS Tools 911.5147 screwdriver bit is engineered for precise fastening tasks and repair work. It has a Torx T55 tip and a work length of 30 mm, combined with a hexagonal shank designed to fit standard bit holders and impact drivers. Lightweight and compact, the bit provides reliable engagement with Torx fasteners while allowing controlled torque application in confined spaces.

Advantages

The Torx T55 geometry ensures a secure fit with reduced cam-out compared to slotted or Phillips types. The 30 mm length offers a balance between access and control for medium-depth screws. The 5/16 inch hexagonal shank provides compatibility with common bit holders and quick-change chucks, and the low weight improves ease of handling during repetitive tasks.

Suitable for

• Automotive repair and maintenance
• Assembly and disassembly of machinery with Torx T55 fasteners
• Electrical cabinet and panel works where medium-reach bits are required
• General workshop and home maintenance tasks involving Torx screws

Key specifications

• Tip type: Torx T55
• Length: 30 mm working length
• Shank shape: Hexagonal
• Shank size: 5/16 inch (127/16 mm equivalent)
• Weight: approx. 10 g

How to use

Insert the hexagonal shank into a compatible bit holder, quick-change chuck, or impact driver. Ensure the bit is fully seated and secure before applying torque. Select appropriate torque settings on electric drivers to avoid over-tightening; for manual use, apply steady pressure and keep the driver aligned with the fastener to prevent slipping. Inspect the tip for wear before use and replace when deformation or rounding is observed.

Usage recommendations

For best results, use the bit with matching Torx T55 fasteners and avoid excessive side load. Store in a dry tool organizer to prevent corrosion and check compatibility with high-torque impact drivers if used under repeated heavy loads.
