Screwdriver Bit Set Wiha 41598 5 pcs

The Wiha 41598 screwdriver bit set contains five PH1 Phillips bits, each 25 mm long with a 1/4" (6.35 mm) hexagonal shank. Made in Germany, the bits are designed for compatibility with standard screwdrivers and power tool holders and for reliable, precise fastening work. Wiha's bit concept simplifies selection: only the screw head shape matters when choosing the correct bit.

Advantages

These Wiha bits feature a patented torsion zone that makes them suitable for use with power tools and impact drivers while extending service life up to 120 times compared to Wiha standard bits for compatible screw types. The bits have a fluorescent coloured coating and blue marking that makes them easy to find, even in low light or under UV illumination, reducing loss and replacement costs.

Suitable for

• General handheld screwdriver work requiring PH1 bits
• Use with power screwdrivers and impact drivers for compatible screw heads
• Assembly and maintenance tasks where quick bit identification is needed

How to use

Select the PH1 bit from the set and insert the 1/4" hex shank into the bit holder of your manual screwdriver, ratchet or compatible power/impact driver. Ensure the bit is seated securely before applying torque. Use appropriate speed and torque settings on power tools for the fastener and material to avoid cam-out or damage. After use, store the bits in their holder to preserve the fluorescent coating and prevent loss.

Usage recommendations

For longest life and best performance, use the Wiha 41598 PH1 bits with screws that match the PH1 profile, avoid excessive lateral force, and select suitable torque settings when using impact drivers. Inspect bits regularly for wear and replace when tip shape degrades.
