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.

Hex Shank Taps for Drills and Screwdrivers

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

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.

Pipe and Conduit Thread Taps

Create threads sized for pipe and conduit.

Long-Reach Pipe and Conduit Thread Taps

With an extra-long shank, these taps have extended reach for tapping deep and hard-to-reach areas in pipe and conduit.

Left-Hand Pipe and Conduit Thread Taps

Tap left-hand threads for pipe and conduit.

Economy Carbon Steel Pipe
and Conduit Thread Taps

Use these carbon steel taps for thread repair and occasional tapping of pipe and conduit. They can tap threads into most metal and plastic, but they have a shorter tool life than standard taps.

Chip-Clearing Pipe and Conduit Thread Taps

Also known as interrupted-thread taps, these have extra space between the cutting threads, so large chips fall without packing and high amounts of lubricant can flow between the tap and the workpiece.

Combination Drill Bit/Pipe and Conduit Thread Taps

Drill and thread holes for pipe and conduit without switching tools.

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 Aluminum, Copper, and Brass

The cutting teeth are shaped to cut smooth threads in soft pipe and conduit material.

Pipe and Conduit Thread Taps for Hardened Steel

Use these taps on hardened steel pipe and conduit.

European Conduit Thread Taps

Cut threads in PG thread sizes commonly used for European conduit.

JIS Thread Taps

Produce metric threads that meet Japanese Industrial Standards.

Taps for Helical Inserts

Add threads to holes in preparation for installing helical inserts.

Coil Thread Taps

The coil-style threads produced by these taps are shallower and more widely spaced than standard thread sizes. Use them for quick threading action with compatible fasteners.

Threading Sets

Tap Sets

These taps are for use on most metal and plastic.

Left-Hand Tap Sets

For start-to-finish tapping of left-hand threads, these sets include one taper-, one plug-, and one bottoming-chamfer tap.

Chip-Clearing Tap Sets for Through-Holes

Sets include multiple tap sizes for threading different hole diameters.

Hex-Shank Tap Sets for Drills and Screwdrivers

Multiple tap sizes allow tapping a range of hole diameters. Connect these taps directly to drills, power screwdrivers, and other tools that accept a 1/4" hex shank.

Pipe and Conduit Tap Sets

Create pipe and conduit threads in a range of hole diameters.

Tap and Drill Bit Sets

Drill and tap a variety of hole sizes. These taps and drill bits are for use on metal and plastic.

Chip-Clearing Tap and Drill
Bit Sets for Through-Holes

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

Hex-Shank Tap and Drill Bit
Sets for Drills and Screwdrivers

All taps and drill bits have a hex shank for direct connection to tools such as drills and power screwdrivers.

Hex-Shank Combination Drill Bit/Tap
Sets for Drills and Screwdrivers
