Screwdriver bit GRAPHITE 56H541, 1/4" drive, 25 mm length

GRAPHITE 56H541 screwdriver bit with a 1/4" drive and 25 mm length is a compact, heavy-duty bit family designed for use with compatible bit holders, manual screwdrivers or impact drivers that accept 1/4" hex shanks. Available in TX10/15/20/25/30/40 sizes, these 25 mm bits are manufactured from S2 steel and include a torsion zone that reduces peak stresses when exposed to high torque, improving resistance to breakage and extending service life. The precisely finished working tip ensures accurate seating in fastener heads for reliable fastening performance.

Advantages

The S2 steel construction provides increased flexibility and resistance to mechanical damage compared with standard tool steels. The torsion zone is engineered to absorb and dissipate torque peaks, reducing the risk of tip fracture during high-torque operations. Short 25 mm length improves access in confined spaces and offers stable control in both manual and powered applications. Precisely machined tips ensure optimal fit with Torx fasteners, reducing cam-out and wear.

Suitable for

• Fastening and assembly tasks with Torx (TX) fasteners in sizes TX10–TX40
• Use with 1/4" hex bit holders, manual screwdrivers, and impact drivers
• Work in confined or shallow-recess areas where a short bit is required
• Applications requiring higher torque resistance and longer bit life

Key specifications

• Drive type: 1/4" hex
• Length: 25 mm
• Material: S2 steel
• Tip style: Torx (TX) — available sizes TX10, TX15, TX20, TX25, TX30, TX40
• Design: torsion zone for torque absorption
• Weight: approximately 26 g

How to use

Select the appropriate Torx size for the fastener and insert the 1/4" hex shank into a compatible bit holder, manual screwdriver handle, or impact driver chuck. Ensure the tip is fully seated in the fastener head before applying torque. For powered drivers, start at low speed to confirm alignment and increase speed as needed. Replace the bit if tip deformation or excessive wear is observed to maintain secure engagement with fasteners.

Usage recommendations

For best results, use the GRAPHITE 56H541 bits with tools that accept 1/4" hex shanks and are rated for impact use when performing high-torque operations. Avoid using worn or damaged bits; inspect the tip and torsion zone regularly. When working in tight spaces, the 25 mm length provides better control — pair with a short extension or low-profile driver if additional reach is required.
