Screwdriver Bit Set Wiha 41596

The Wiha 41596 screwdriver bit set contains five T30 Torx bits, each 25 mm long with a 1/4" (4 mm) hexagonal shank. Made in Germany, these bits use Wiha's specialised T-bit design with a patented torsion zone that allows use with power tools and impact drivers while providing a significantly extended service life. A fluorescent blue coating makes the bits easy to locate, even under UV light.

Advantages

The T-bit design makes selection straightforward: only the screw shape matters when choosing the correct bit. The patented torsion zone increases durability, offering up to 120× longer lifespan compared to Wiha standard bits, and permits safe use with impact screwdrivers. The fluorescent coating and blue marking speed up bit identification and reduce replacement costs by lowering loss rates.

How to use

Select the T30 bit from the set and insert it into a compatible 1/4" bit holder or the chuck of the screwdriver or impact driver. Apply steady pressure and engage the driver with the screw head, keeping the bit aligned with the screw axis. For power or impact tools, start at low speed to ensure correct seating, then proceed at the appropriate speed and torque for the application.

Recommendations

Use the bits with correctly sized T30 screws and maintain alignment during use to maximise lifespan. Store the bits in a designated holder to reduce loss and protect the fluorescent coating for optimal visibility under UV light.
