Screwdriver Bit Set Wiha 42136

The Wiha 42136 Screwdriver Bit Set contains an innovative BitBuddy® holder and a selection of Torx/TY bits designed for fast, simple bit changes and reliable fastening. The set includes eight 29 mm Torx bits (T10, T15, T20, T25, T30, T40) arranged in a lasered-profile holder that makes bit sizes easy to read and select. Bits feature a strong magnetised base for single‑handed operation, a patented torsion zone for use with power tools and impact drivers, and a fluorescent coating for fast visual identification.

Advantages

The BitBuddy® holder allows positioning bits directly in the tool and returning them to the holder with one hand thanks to its strong magnet and ergonomic layout. The lasered profile size on each bit base simplifies correct selection. TY/Torx bits are universal for both T-shaped and Y-shaped screws. The patented torsion zone extends bit life (up to 120× longer than Wiha standard bits under rated conditions) and makes the bits suitable for use with powered and impact screwdrivers. Fluorescent colouring improves visibility in low light and reduces loss.

Suitable for

• Assembly and disassembly of Torx/TY fasteners in electronics and appliances
• Maintenance and repair work that requires frequent bit changes
• Use with manual screwdrivers, power screwdrivers and impact drivers
• Professional and DIY precision applications

How to use

Select the required Torx/TY bit from the lasered holder by reading the size marking, then attach the bit to your screwdriver or power tool. The magnetic BitBuddy® holder permits single‑handed removal and replacement of bits: position the bit against the tool's holder, let the magnet hold it, and return the bit to its slot after use. For power or impact drivers, the torsion zone absorbs peak loads; ensure the tool is set to the appropriate torque and follow the tool manufacturer's guidance.

Usage recommendations

Use the bits within their intended torque range and inspect them regularly for wear. Store the bits in the BitBuddy® holder to maintain order and prolong service life. Avoid excessive side loads and use the correct bit size to prevent damage to fasteners and bits.
