T3 Torx Insert Bit for 1/4" Shank

The Tuff Stuff TX3100 is a single-ended T3 Torx insert bit designed for drills and screwdrivers that accept a 1/4" shank. It serves as a general-purpose fastener tool for tightening and loosening tasks around the home, shop, or garage. The one-inch length provides standard reach for common applications.

Replaces Worn or Missing T3 Bits

Swap this in when an existing T3 bit strips, rounds over, or goes missing from a set. The jump is worth it when the damaged bit risks rounding Torx fastener heads or when a job requires a fresh, precise tip profile. It restores positive engagement without needing a full kit replacement.

Fits 1/4" Hex Drive Tools Directly

The 1/4" hex shank seats in standard quick-change chucks, impact drivers, and drill drivers with no adapter required. Its single-ended design keeps the working tip clear for straight-line access in tight spots. The bit frees up a slot in an organiser by covering the T3 size alone.

Questions about this item

Will the 1/4" shank on this TX3100 bit fit my impact driver's chuck?

The 1/4" shank matches standard quick-change chucks on most drills and impact drivers, so it locks in without an adapter.

How do I seat the bit fully so it does not wobble during use?

Push the bit into the chuck until the shank bottoms out, then tighten the sleeve or trigger the auto-lock; a partial insert causes run-out.

When should I replace this T3 Torx bit instead of continuing to use it?

Replace it when the six-lobe tip shows rounding or stripped edges, because a worn tip damages fastener heads and reduces torque transfer.
