T4 Torx Insert Bit

The Tuff Stuff TX4100 is a single-ended Torx bit tip sized #T4. It is built for general-purpose fastening tasks in the home, workshop or garage. The accessory fits any drill or screwdriver that accepts a standard 1/4 inch shank.

Critical specification

The defining detail is the #T4 Torx tip profile; only fasteners with a matching T4 recess will engage correctly. Using this bit on other Torx sizes or drive types will damage both the bit and the screw head.

Build integration

The 1/4 inch shank locks directly into quick-change chucks and standard drill chucks without an adapter. Its one inch overall length keeps the working tip close to the chuck for better control in tight spaces. The bit is not suited for impact drivers rated above the bit's torque limit or for recessed fasteners requiring a longer reach.
