Sada bitov do skrutkovača Wiha 42107

The Wiha 42107 screwdriver bit set contains five 29 mm long 1/4" hex bits designed for precise fastening tasks. These bits use Wiha's universal TY concept that makes bit selection depend only on the screw head shape. The set is lightweight (70 g) and intended for a wide range of materials and applications where both T-shaped and Y-shaped screws are encountered.

Advantages

Wiha's multitalented TY bits fit both T- and Y-shaped screws, eliminating the need to match bits to the tool or fastening type. A patented torsion zone allows safe use with power tools and impact screwdrivers while providing a significantly longer service life — up to 120 times the lifespan of standard Wiha bits. The bits feature a fluorescent coating for easy identification, including under UV light, which reduces loss and replacement costs.

How to use

Select the appropriate TY bit for the screw head, insert the 1/4" shank into a compatible bit holder or driver, and engage the screw head. The torsion zone allows use with power tools and impact drivers; operate at recommended torque settings for the screw and material to avoid damage. After use, store bits in their case or a magnetic holder to keep the fluorescent coating visible and reduce loss.

Recommendations

Use the bits with compatible 1/4" bit holders and adjust torque on power tools to match screw and material specifications. Inspect bits periodically for wear and replace when deformation appears to maintain safe and reliable fastening.
