T40 Torx Insert Bit for 1/4" Shank Tools

The Tuff Stuff TX40100 is a single-ended Torx bit sized for T40 fasteners and built to fit any drill or driver that accepts a 1/4" shank. It serves technicians and DIY users who need a dependable bit for everyday tightening and loosening tasks around the home, shop or garage.

Build integration: 1/4" shank compatibility

Because the bit uses a standard 1/4" shank, it slots directly into the chuck of most cordless drills, impact drivers and pneumatic screwdrivers without an adapter. This frees up space in a tool bag by removing the need for dedicated T40 drivers and lets the user switch between drilling and driving with one tool.

Sustained use: durable tip geometry

The hardened tip geometry resists rounding when driven repeatedly into stubborn or corroded fasteners, so the bit keeps its grip over long sessions rather than stripping after a few high-torque impacts. It is not suited for buyers who need longer reach beyond the 1" length or who require a double-ended design for rapid tip changes.
