As you might expect, Pipe Taps are the types of thread taps used for tapping pipe threads. There are both straight and tapered pipe taps depending on whether the pipe thread is intended to be straight or tapered. The photo shows a typical NPT Thread Pipe Tap. You can see the taper of the NPT thread

Tap Fractional Drill Bit Number Drill Bit Letter Drill Bit Carbide Pipe Taps Regal Cutting ToolsTapping non-ferrous highly abrasive materials using carbo-clad taps give you the cutting performance of carbide and the shock absorbency of the high speed body. Strips of micrograin carbide are brazed in the body of a HSS tap and precision ground to assure superior thread quality and extremely long tool life. Select coatings can be applied to enhance the performance.

How To Use NPT Thread Gages - The Gage Store - The There are no recognized L2 or L3 or 6 step gages for NPT threads. The reason is that NPT threads are used with a sealing component like Teflon tape or pipe dope that makes up the leak proof seal. The NPT thread is more forgiving of the wrench tight check that is required on NPTF (dry seal) and the taper or crest check is again not specified.

Pipe and Conduit Thread Tapsfor 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 Taps are High Speed Steel cutting tools designed for the internal threading of pipes and pipe fittings. Ground thread provides tighter tolerances and better surface finishes. Various pipe tap models exist for various standards:NPT (American Standard Taper Pipe Threads), SAE (American Standard Short Projection Pipe Thread), NPTF (Dryseal American Standard Taper Pipe Threads), NPS (American Standard Straight Pipe Threads), BSPP (British Standard Pipe Pipe Thread Tap and Drill Size Chart ANSI NPT - Engineers National Pipe Thread Taper ( NPT ) is a U.S. standard for tapered threads used on threaded pipes and fittings . In contrast to straight threads that are found on a bolt, a taper thread will pull tight and therefore make a fluid-tight seal. Threaded pipes can provide an effective seal for pipes transporting liquids , gases , steam , and hydraulic fluid. These threads are now used in materials other than steel

Many are cutting tools; others are forming tools. A tap is used to cut or form the female portion of the mating pair (e.g. a nut). A die is used to cut or form the male portion of the mating pair (e.g. a bolt).

- UseApplicationsDetailsTypesTaps are used to cut internal threads in valves, couplings, unions or fittings that will be mated with threaded pipe or fittings to make a pressure tight joint. Selecting taps for cutting taper pipe threads requires some investigation to ensure two important requirements are met. First, to provide the correct mating threads in the assembly and secondly, choosing the right style tap to meet specifications and produce quality threaded parts in the quantity required. The most common American styles are NationPipe Taps Technical Information MSC Industrial Supply Co.Pipe Taps are used to cut internal threads in parts or fittings that will be mated with threaded pipe or fittings to make a pressure tight joint.Pipe threads require higher cutting forces than regular machine thread tapping because the threads require 100% thread depth. Most threads on tapered pipe taps
The thread tap limits are designated by the letter D (ground, high) above basic pitch diameter, or U (ground, low) below basic pitch diameter. As an example, in sizes M25 and smaller, a D1 tap has a size of .0005 over basic to tap max. P.D.; a D2 tap has a size of .001 over basic to tap max. P.D., (see Chart
