Wiha 71910 Screwdriver Insert Bit 10 Point 6.3 Mm Hex Drive

Product Description

The WIHA 71910 is a 10-point screwdriver insert bit designed for use with 6.3 mm hex drive power tools and bit holders. The bit measures 25 mm (1 inch) in overall length, making it a standard 1-inch insert format compatible with most quick-change driver systems. Each package contains 10 bits. WIHA insert bits are built for repetitive fastening tasks where bit wear is a factor and quick replacement keeps work moving. This bit is suited for trade professionals who drive 10-point fasteners in electrical, HVAC, or general mechanical assembly applications.

The 71910 fits standard 6.3 mm hex bit holders and power screwdriver chucks used in residential and light commercial service work. The 25 mm insert length is the most common format for cordless drill drivers, impact drivers, and bit extension bars used in panel assembly, equipment mounting, and fixture installation. A pack of 10 provides enough quantity for shop stocking or job-site kits where bit replacement is routine.

Installation Notes

Insert bits are installed and replaced by hand — no tools required for bit changes on standard quick-change holders. Ensure the bit is fully seated in the holder before applying torque to avoid cam-out or tip damage. Inspect bit tips for wear regularly; replace worn bits promptly to protect fastener heads. No power shutdown procedures apply to bit changes, but always follow safe tool-handling practices when working near energized equipment.
