Drill Bit Wiha 41651

The Wiha 41651 drill bit is a 50 mm long bit with a hexagonal shank designed for fastening T-shaped screws and for general use with hex-compatible holders. The bit follows Wiha's bit concept where screw shape determines the correct bit; the 41651 is shaped to fit T-type screws and is suitable for both hand and powered use. It includes a patented torsion zone that increases service life and a fluorescent coating that makes the coloured bits easy to find under UV light.

Advantages

The torsion zone provides higher resistance to breakage and allows safe use with power tools and impact screwdrivers, delivering a significantly longer lifespan compared with standard bits. The hexagonal shank ensures secure fitting in compatible chucks and holders. Fluorescent coating improves visibility in low light and reduces loss of bits.

How to use

Insert the hexagonal shank into a compatible bit holder, chuck or screwdriver. Align the T-shaped tip with the screw head and apply steady pressure while turning. For power tools or impact drivers, use an appropriate speed and torque setting to avoid overloading the screw or bit. After use, store the bit in a holder or box to protect the fluorescent coating and prolong service life.

Recommendations

Use the Wiha 41651 bit with compatible SW4 hex holders and, when using impact drivers or power tools, select moderate torque settings. Inspect the torsion zone and tip for wear regularly; replace the bit when wear affects fit or performance.
