Taps

General Purpose Taps

Cut threads into most metal and plastic.

Long-Reach General Purpose Taps

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

Left-Hand General Purpose Taps

Tap threads for left-hand threaded fasteners.

Oversize General Purpose Taps

Sized to cut oversized threads, these tools are often used to tap holes where the threads will shrink due to heat treatment or plating.

Economy Carbon Steel Taps

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.

Carbide Taps

Use these taps on hard and abrasive material, such as heat-treated metal, nickel, and fiberglass.

Chip-Clearing Taps for Through Holes

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.

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.

Oversize Chip-Clearing Taps for 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.

Left-Hand Chip-Clearing Taps for Through Holes

These taps cut left-hand threads while keeping chips clear.

Chip-Clearing Taps for Closed-End Holes

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

Chip-Free Forming Taps

Also known as cold-forming and fluteless taps, these press threads into material without cutting it, so no chips are created.

Hex Shank Combination Drill
Bits/Taps for Drills and Screwdrivers

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.

Combination Drill Bit/Taps

Drill holes and cut threads without switching tools.

Taps for Steel and Stainless Steel

These taps are made of cobalt steel for higher strength and wear resistance than standard taps. Their flutes are designed to keep chips clear, so they don't need to be reversed to prevent buildup.

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.
