Wiha 74556 T27 Torx Power Screwdriver Bit 2.75 in 10-pack

Product Description

The WIHA 74556 is a T27 Torx power screwdriver bit designed for use with power drivers and electric screwdrivers in demanding trade and industrial applications. With an overall length of 2.75 inches and a 0.25-inch drive size, this bit delivers the reach and engagement needed for fastening in recessed or hard-to-access locations. Constructed from steel, it is built to withstand the torque demands of power tool use. This package contains 10 bits, making it a practical choice for crews that go through tooling regularly or need consistent replacements on hand.

This bit is suited for electrical, HVAC, plumbing, and general mechanical trades where T27 Torx fasteners are commonly encountered. The 2.75-inch overall length provides additional reach compared to standard-length insert bits, useful when working inside panels, equipment enclosures, or tight mounting configurations. The 10-piece pack format supports tool crib stocking and job-site replenishment without repeated individual ordering.

Compatibility

Designed as a power screwdriver bit for use with standard 0.25-inch hex shank power drivers and electric screwdrivers that accept T27 Torx bits.

Installation Notes

Verify the power driver is powered off and the bit holder is fully seated before inserting the bit. Confirm the bit shank is fully engaged in the chuck or magnetic holder before applying torque. Inspect bits regularly for wear or deformation and replace any bit that shows signs of stripping or rounding to avoid fastener damage.
