Screwdriver Bit Set Wiha 42133

The Wiha 42133 screwdriver bit set contains five Torx T30 bits, each 49 mm long with a 1/4" shank. Designed for precision and durability, these bits are suitable for a wide range of fastening tasks and are lightweight at 84 g.

Advantages

The multitalented TY bit concept used by Wiha makes the screw head shape the only criterion for selection, allowing these bits to work with both T-shaped and Y-shaped screws. A patented torsion zone permits use with power tools and impact drivers while extending service life up to 120 times compared to Wiha standard bits. Fluorescent coloured coating improves visibility and helps locate bits even under UV light, reducing losses and replacement costs.

How to use

Select a T30 bit from the set and insert the 1/4" shank into a compatible bit holder or screwdriver. Use the bit to engage the Torx fastener, applying steady pressure while turning. For power or impact screwdrivers, ensure the tool settings match the task and allow the torsion zone to absorb peak loads to protect the bit and fastener.

Recommendations

Inspect bits for wear before use; replace severely worn bits to avoid cam-out or damage. Store bits in a clean, dry holder and use the fluorescent coating and UV light for quick location. Match bit size (T30) precisely to the screw for optimal performance.
