Wiha 28529 Torx Torque Blade Bit T9 8.75 in

Product Description

The WIHA 28529 is a T9 Torx torque blade screwdriver bit designed for precision fastening applications where controlled torque delivery is critical. The bit measures 8.75 inches in overall length and features a 1/8 inch hex shank for compatibility with standard hex-drive handles and power tool adapters. This style of blade is commonly used when access depth or torque sensitivity is a factor, making it a practical choice for technicians working on equipment with Torx fasteners in confined or sensitive assemblies.

This bit is suited for trade professionals and technicians who regularly service equipment secured with T9 Torx fasteners. Typical applications include electronics-adjacent assemblies, HVAC control panels, appliance enclosures, and electrical equipment where small Torx fasteners are standard. The extended 8.75-inch length provides added reach in tight or recessed installations where a standard-length bit would be impractical.

Key Features

• T9 Torx drive for compatibility with small-headed Torx fasteners in trade equipment
• 8.75-inch overall length for extended reach in recessed or deep fastener locations
• 1/8 inch hex shank fits standard hex-drive bit holders and adapters
• Torque blade design helps prevent fastener and bit damage from over-torquing
• Lightweight at 0.07 pounds for easy single-hand use

Compatibility

Designed for use with standard 1/8 inch hex-drive bit holders, T-handles, and compatible power tool adapters that accept hex shank bits.

Installation Notes

This bit is installed by technicians and trade professionals using compatible hex-drive handles or adapters. Confirm the hex shank is fully seated in the holder before applying torque. Inspect the bit tip for wear before each use, as a worn Torx tip can strip small fasteners. Do not use impact drivers with this torque blade style bit unless the handle or adapter is rated for impact use.
