McMaster-Carr

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 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.

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
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.

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

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.

European Conduit Thread Taps

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

Internal Pipe and Conduit
Thread Repairing Files

Repair rusted and damaged threads in pipe and conduit. These files are for use in most hole diameters.

Threading Sets

Tap and Die Sets

Use a single set for many sizes of internal and external threads. All sets include tap and die wrenches.

Tap, Die, and Drill Bit Sets

Cut and repair threads and drill holes in many different sizes. Tap and die wrenches are included.

Pipe and Conduit Tap Sets

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

Tap Valves

Also known as saddle valves and humidifier valve clamps, these self-piercing valves allow you to tap existing copper tubing lines to redirect a small amount of liquid for on/off control of a secondary line.
