Tapping Bits | McMaster-Carr

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.

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.

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.

Taps with Two Threading Ends

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.

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 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.

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.

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.

Pipe and Conduit Thread Taps
with Two Threading Ends

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.

Combination Drill Bit/Pipe
and Conduit Thread Taps

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

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.

Pipe and Conduit Thread
Taps for Shallow Holes

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.

Pipe and Conduit Thread
Taps for Hardened Steel

Made of cobalt steel, these taps are for use on hard pipe and conduit material, such as hardened steel.

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 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.

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.

Thread Mills

Cut a range of thread sizes with a single tool. These thread mills can also produce both right-hand and left-hand threads.

Taps for Helical Inserts

Add threads to holes in preparation for installing helical inserts.

Garden Hose Thread Taps

Tap the unique size needed for garden hose thread (GHT) connections.

Compressed Gas Thread Taps

Also known as National Gas Outlet (NGO) taps, these tap threads in sizes used for compressed gas cylinders and valves.

Acme Thread Taps

Form general purpose Acme threads.

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.

Spark Plug Thread Taps

Use these high-speed steel taps to cut and repair threads in the sizes needed to accept spark plugs.

Tap Holding, Guiding, and Storing

T-Handle Tap Wrenches

Use with a tap to thread holes by hand. These wrenches are more compact than straight-handle tap wrenches, so they can be used to tap in tighter spaces.

Economy T-Handle Tap Wrenches

Connect a tap to these wrenches for occasional or light-duty hand tapping. All have a T-handle design, so they're more compact than straight-handle tap wrenches but provide less leverage.
