Wiha 71546 T30 Torx Insert Bit 1/4 Inch Drive 10-pack

Product Description

The WIHA 71546 is a T30 Torx insert bit designed for 1/4 inch hex drive screwdrivers, bit holders, and power tool adapters. Built from steel with a standard 25 mm (approximately 1 inch) overall length, this bit fits the common insert-bit format used across HVAC, electrical, and general mechanical service work. The T30 Torx profile provides a high torque transfer with reduced cam-out compared to Phillips or slotted fasteners. Each package contains 10 bits, making it a practical choice for stocking a service van or tool crib.

This insert bit is suited for residential and light commercial service applications where T30 Torx fasteners are encountered. Common use cases include HVAC equipment panels, electrical enclosures, appliance service, and general equipment assembly or disassembly. The 1/4 inch hex shank is compatible with standard quick-change bit holders, magnetic extensions, and most cordless drill or impact driver chucks that accept 1/4 inch hex accessories. The 10-piece pack is appropriate for shops and technicians who go through bits regularly in high-cycle field work.

Installation Notes

Insert bits are installed and removed by hand into compatible 1/4 inch hex bit holders or chucks — no tools required for bit changes. When using with a power tool, confirm the driver torque setting is appropriate for the fastener size to avoid stripping T30 sockets. Inspect bits periodically for wear or rounding of the Torx lobes, and replace worn bits before they damage fastener heads.
