Long-Reach Chip-Clearing Taps for Through Holes

Clear chips while tapping deep and hard-to-reach holes. These taps have an extra-long shank for extended reach.

Taps for Aluminum, Brass, and Plastic

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

Taps for Hardened Steel and Iron

Tap threads into hardened steel and iron. These cobalt steel taps have straight flutes for high durability.

Taps for Nickel

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.

Taps for Titanium

A high helix angle provides the cutting strength needed to tap threads in titanium. These cobalt steel taps have an open flute design that keeps chips clear, so they don't need to be reversed to prevent buildup.

Pipe and Conduit Thread Taps
for Stainless Steel and Plastic

The spiral flutes on these pipe and conduit taps keep chips clear by drawing them back out of the hole, so there's no need to reverse the tap while cutting threads.

Pipe and Conduit Thread Taps for Hardened Steel

Use these taps on hardened steel pipe and conduit.
