Bity do skrutkovača Wiha 41644 5 kusov T15 50 mm

The Wiha 41644 set contains five T15 screwdriver bits, each 50 mm long with a 1/4" (6.35 mm) hexagonal shank designed for use in hand tools, bit holders and compatible power tool adapters. The bits follow Wiha's bit concept where screw geometry alone determines the correct bit: the T-bit shape matches T-shaped (Torx) screws with a 90° relation between thread and screw head. A patented torsion zone improves durability and allows safe use with power tools and impact drivers, while a fluorescent coating makes the coloured bits easy to find, even under UV light.

Advantages

These Wiha T15 bits combine a torsion zone that reduces breakage under torque with wear-resistant manufacturing for a significantly longer service life compared to standard bits. The uniform screw-shape-based selection simplifies choosing the right bit, the 50 mm length provides access in tighter recesses, and the fluorescent coating improves visibility and reduces loss. The 1/4" hex shank ensures compatibility with common bit holders and quick-change chucks.

How to use

Select the T15 bit when working with T15 (Torx) screws, insert the 1/4" hex shank into a compatible bit holder, screwdriver or power tool adapter and engage the screw head fully before applying torque. For use with impact drivers or high-torque tools, allow the torsion zone to absorb shock loads; avoid excessive lateral forces and ensure correct alignment to prevent cam-out or damage to the screw head.

Recommendations

Use the bits with the correct T15 designation only; store them in a designated case to preserve the fluorescent coating and reduce loss. When using power tools, start at low speed to seat the bit and then apply controlled torque.
