The Tuff Stuff TW3100 is a single-ended Tri-Wing insert bit sized at #3 with a 1-inch overall length. It fits any drill or driver that accepts a 1/4-inch hex shank. The bit is manufactured for general-purpose fastening tasks in home, shop and garage environments. It is supplied as a new, individual piece.

DIY users and light trade work

This bit suits anyone driving or removing Tri-Wing #3 fasteners with a standard 1/4-inch hex chuck. It is not intended for high-volume production lines or impact-rated applications that demand hardened impact bits. Buyers who need a different tip size, a longer reach or a double-ended design should look at other options.

1/4-inch hex shank compatibility

The 1/4-inch hex shank is the single specification that determines whether this bit fits your tool. Verify that your drill, driver or bit holder accepts 1/4-inch hex shanks before purchasing.

Questions about this item

How long is the Tuff Stuff TW3100 bit and will it reach deep-set fasteners?

The bit measures 1 inch overall, so it reaches only shallow or surface-level screws; deeper recesses need a longer bit.

Does the 1/4-inch shank bit generate noticeable heat during extended driving?

It is a simple steel insert bit with no moving parts, so heat build-up is minimal and only comes from friction in the fastener.

What drive tool must I already own to use this Tri Wing #3 bit?

You need a drill, driver or bit holder that accepts a standard 1/4-inch hex shank.
