Tap threads for left-hand threaded fasteners.

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

With a drill bit point to drive into the workpiece, these taps can drill and tap holes in a single step. A 1/4" hex shank connects them directly to tools such as drills and power screwdrivers.

Drill holes and cut threads without switching tools.

Coated with chromium carbide or titanium carbonitride (TiCN), these cobalt steel taps cut smoothly through soft material to produce accurate threads.

To tap nickel and other hard material, these cobalt steel taps have high cutting strength. Their flutes are designed to keep chips clear, so they don't need to be reversed to prevent buildup.

Add threads to holes in preparation for installing helical inserts.

Form general purpose Acme threads.
