What are the 3 different taps?
There are 3 main taps you should be familiar with and they are: Taper, Plug, and Bottoming tap. The taper tap can be identified by the visible and pronounced tapering of the cutting edges. This provides a very gradual and less aggressive cutting action.
What taps for stainless steel?
Titanium Carbonitride (TiCN) is harder and more wear resistant than TiN. It is used on stainless steels, cast iron and aluminum alloys.
What are the three taps for each diameter and thread series?
Hand taps are usually provided in sets of three taps for each diameter and thread series. Each set contains a taper tap, a plug tap, and a bottoming tap. The taps in a set are identical in diameter and cross section; the only difference is the amount of taper (see figure 12-27).

What is a second tap used for?
They are used to produce threads close to the bottom of blind holes. SECOND TAPS have a lead of 3-5 threads at 8 degrees per side. They are the most popular and can be used for through holes, or blind holes where the thread does not need to go right to the bottom.
Which tap do you use first?
There are times when a Plug tap can be used to start a thread without using a taper tap first if the Plug tap is started with a guiding center or fixture. In blind hole applications, Plug taps are used after a Taper to get closer to the bottom of the hole.
What is first second and third tap?
The one with the longest lead is referred to as the taper or the first tap. The second or intermediate tap and the third which has a very short lead, as the bottoming or plug tap. The bottoming tap (plug) is used to finish the threads of a blind hole to the correct depth.
What do the numbers on taps mean?
They are the grooves or valleys cut into the body of the tap. Higher numbers of flutes increase the strength of the tap and reduce space or chip flow. Thread size is the number of Threads Per Inch (TPI) which is measured along the length of the tap.

Is it hard to tap stainless steel?
Though noted for its strength, stainless steel does not rank among the hardest materials you are likely to encounter in your metal work. The problem is that many stainless steels – 304 and 316 in particular – can get harder and tougher to cut as you work if the cutting tools are improperly applied.
Can you machine stainless steel with HSS?
Either high speed steel, (HSS), (wrought or sintered), or cemented carbide tools can be used for machining stainless steels. Either tungsten or molybdenum HSS can be used.
Will HSS cut stainless steel?
To drill through stainless steel, you need an HSS (High-Speed Steel) drill bit. HSS drill bits have sharp edges that can cut into the tough metal. To cut into hardened stainless steel, you will require a drill bit with a large point angle of at least 130 degrees.
Can you drill stainless steel with HSS?
HSS or High-Speed-Steel bits are designed for use on stainless steel and can be used for hand and machine drilling. It is recommended to use an HSS bit that is TiN tipped as the Titanium Nitride reduces friction which in turn reduces work hardening caused by excessive heat and minimises flank and crater wear.

Flange taps are located 1 inch upstream and 1 inch downstream of orifice plates for pipe sizes greater than 2″, and cannot be used for pipes smaller than 1.5″ diameter, but not recommended below 2″.
Where are vena contractive taps located?
Vena-contractive taps. Vena-contractive taps are located 1 pipe upstream and the downstream tap is located at the point of minimum pressure to ensure a maximum differential pressure. These taps are for small pipe diameters and they are similar to flange taps.
What is a radius tap?
Radius taps are more standardized taps that keep one radius of a pipe up to one diameter of pipe upstream, but the downstream tap is located 1/2 of a pipe diameter downstream. Both vena-contractive and radius taps are recommended for pipes 6″ or larger.
What is an orifice plate pressure tap?
They are used to allow the transmitter to tap into the pipe to measure the high and low pressure sides of the flow.
How many pipe diameters should an orifice plate be?
Orifice plates should generally be installed at least 4-5 pipe diameters from a bend or elbow. You can purchase straightening veins to minimize straight-run requirements. Orifice plates are easy to install and maintain. They are used with a wide variety of pipe diameters, and can be accurate.
Do elbow taps have an orifice plate?
Elbow taps. Elbow taps do not use an orifice plate. They rely on differential pressure when fluid flows around an elbow. These taps are highly inaccurate, but are cheap to purchase and easy to install.

What is the difference between 316L and 316L?
Differences Between 316 and 316L. 316 stainless steel has more carbon in it than 316L. This is easy to remember, as the L stands for "low.". But even though it has less carbon, 316L is very similar to 316 in almost every way. Cost is very similar, and both are durable, corrosion-resistant, and a good choice for high-stress situations.
What is 316 stainless steel?
Type 316 steel is an austenitic chromium-nickel stainless steel that contains between two and 3% mol ybdenum. The molybdenum content increases corrosion resistance, improves resistance to pitting in chloride ion solutions, and increases strength at high temperatures.
Why is 316L used for welding?
Consequently, 316L is used when welding is required to ensure maximum corrosion resistance.
Is 316L stainless steel good for welding?
316L, however, is a better choice for a project that requires a lot of welding because 316 is more susceptible to weld decay than 316L (corrosion within the weld). However, 316 can be annealed to resist weld decay. 316L also is a great stainless steel for high-temperature, high-corrosion uses, which is why it's so popular for use in construction ...
Is 316L the cheapest?
Neither 316 nor 316L is the cheapest option. 304 and 304L are similar but lower-priced. And neither are as durable as 317 and 317L, which have higher molybdenum content and are better for overall corrosion resistance.
How many threads does a blind hole tap need?
In some cases the lead of the tap is reduced to as little as 1.5 threads. This greatly increases torque and reduces tap life.
How many threads does a chamfer tap have?
For a specific tap recommendation for your application, please consult your tap supplier. With 6 to 8 Threads Chamfer Length or Lead. These taps do not transport the chips out of the hole. For this reason, they should not be used for deep hole tapping.
What is the relief angle on a gage thread?
The relief angle effects true to gage thread cutting, and also the free cutting ability and life of the tap. It has an effect on how the tap is guided when it enters the hole. If the relief angle is too great pitch guidance and self centering of the tap can not be guaranteed especially in soft materials. In materials like stainless steel or bronze the relief angle should be larger to allow free cutting and to allow more lubrication to reach the cutting and friction surfaces. A bigger relief angle can allow higher tapping speed provided the tap is guided concentrically into the hole by the machine and tap holder.
What is the best rake angle for a tap?
The best rake angle for a tap depends on the material. Materials that produce long chips normally require a tap with greater rake angle. Materials that produce short chips require a smaller rake angle. Difficult materials like Titanium or Inconnell require a compromise between greater rake angle for longer chips and smaller rake angle ...
Why is the relief angle smaller on taps for blind holes than on taps for through holes?
The relief angle is smaller on taps for blind holes that on taps for through holes so that the chip root can be sheared off when the tap reverses without breaking the taps cutting edge.
Why are the chips curled up in flutes?
These taps push the chips forward. The chips are curled up to prevent logging in the flutes. They are used for through holes.
What material can be cut with a small relief angle?
Harder materials like stainless steel can be cut easier with a tap having a greater relief angle which reduces the friction. Tough materials like Inconnel and nickel can be cut more easily with an even greater angle.
