Cut threads into most metal and plastic.

Use the extra-long shank to thread deep and hard-to-reach holes.

Often used for thread repair and occasional hand tapping, these carbon steel taps can thread holes in most metal and plastic, but they have a shorter tool life than standard taps.

Keep chips clear while tapping. Also known as gun taps, these have spiral-point flutes that push chips ahead of the tap and out of through holes.

Create oversized threads while keeping chips clear. These taps are sized for use in holes where the threads will shrink due to heat treatment or plating.

The spiral flute design pulls chips back toward the tap, so chips won't accumulate in closed-end holes.

Insert these taps directly into drills, power screwdrivers, and other tools that accept a 1/4" hex shank.

With a taper chamfer and bottoming chamfer at opposite ends, these taps start threads easily and are good for threading close to the bottom of closed-end holes.

Create threads sized for pipe and conduit.

Tap left-hand threads for pipe and conduit.

Also known as short-projection taps, these have fewer tapered threads at the tip than standard pipe taps, so you don't have to drive them as deep to produce full threads.

With a taper chamfer on one threading end and a bottoming chamfer on the other, these pipe and conduit taps can start threads easily, and they are able to thread close to the bottom of closed-end holes.

Restore bolt, hole, pipe, and conduit threading with this set of four files.

Repair rusted and damaged threads in pipe and conduit. These files are for use in most hole diameters.

With replaceable dies, these long-lasting tools can repair both screw threads and pipe and conduit threads. Use them for holes with an ID from 3/4" to 6".
