Tap and Die Set Metric and Standard [with Sizes Chart]

Tap and die sets are a way to cut and copy your designs into different materials easily. Tap and die sets also have the capacity to include the number of layers you want to use.

And so, you can easily switch out one layer for another without having a hard time with the designs.

According to Tameson, “A tap and die set consists of taps, dies, and drill bits of different sizes for various applications. The collection also consists of screw extractors and charts to determine the correct drill and taps to match the thread size and pitch.”

In this article, we compiled all information that you need to know about Metric Tap and Die Set Charts.

Types of Tap

There are many types of tap and die sets available on the market. You can find something that suits you and your budget. Some sets come with a storage bag, and some do not. If you’re not sure which one to choose, check out some tips to help you choose wisely.

Types of Taps

Taper Tap

Thread cutting with tapered taps is used on the butt cut, top section cut, and shears. The default depth of cuts can be adjusted using the depth setting. For additional information, refer to the Cutting Guides.

Second Tap

You can easily increase the speed of cutting with a second tap. A second tap cuts at the same depth as the first tap but is applied more quickly. This allows you to cut more quickly and with less material; you also need less pressure when cutting.

When the thread is cut, a second tap is placed on the topmost cutting surface to increase the depth of the cut. This helps to maintain the pitch of the thread at its original pitch and prevents the migration of threads after cutting.

Plug Tap

Plug taps are used to produce clean results at the hole’s end. A plug tap is a device used in the hole’s end of a pipe. It has a hammer and a bolt driven into the hole to allow for proper pressure distribution. The hammer strikes the pipe while the bolt is released from it.

Types of Die Sets

Circular Dies

A circular die is essentially a small machine that spins, or rotates, on itself. This makes it possible to produce threads in a single operation. You can use a circular die for everything from making the thread, to sewing, on buttons and zippers.

Two-Piece Adjustable Dies

Two-piece adjustable dies are used in order to make longer threads. Two-piece dies are used in manufacturing thread that is used in a range of different products and fields, such as sewing machines and all types of knitting. The quality of the thread depends on the quality of the dies.

How to Measure a Tap & Die Bit

The process of measuring for a die is usually done with a tape measure. To minimize the chances of error, it is important to know the various measurements that are associated with tap and die measurements. Here are the steps you may follow.

Step One

You will find that whether you are dealing with a screw or a bolt, the threads have a very important role in making a good product. The thread is important for being able to create a strong bond between the parts that makes it possible for them to fasten together. It is also important that you get the right thread size for your application.

Step Two

Count threads per inch. The thread count is a measurement that tells you how many threads of a given kind per inch are in a piece of fabric. The higher the thread count, the more thread per inch. In clothing, it’s important to know if a particular fabric has a very high thread count, which makes the fabric feel heavy when you wear it.

Step Three

There are two types of threads: National Fine and National Coarse. A fine thread measures 20-25 feet per inch, while a coarse thread measures 40 feet per inch.

Step Four

Take a look at the number you just collected. Compare it to the numbers written on the taps and dies. The 1/4-20 N.C. tap is a standard soldered thread that’s a great way to measure fasteners and other mechanical parts, but it’s also a great tool for measuring items with 20 National Coarse threads per inch.

The use of metric taps and measuring devices is required in most engineering and construction works. A metric taps and measuring device ensures accurate measurements. It can be used anywhere, anytime, regardless of the soil, water, air, and atmosphere conditions.

Metric Die Set Chart

A metric die set chart is a tool for measuring thickness. It is a measurement of the thickness of steel, from which you can get a rough idea of the thickness of the steel.

The die set chart helps you determine how thick a steel sheet stock should be, and it also lets you know how much a certain thickness of steel will cost.

Correct Way To Use Tap and Die Set with Chart

A tap and die set is a crucial tool in any design studio. It helps you control the piece’s dimensions and cut out shapes and modify parts of your designs. There is a lot of confusion about how to use tap and die, so we’ll try our best to simplify it for you.

A tap and die set chart is a chart that shows the location and dimensions of a die in relation to the size of its holes. This allows you to quickly and easily trace a line or other shape in the dies, which you’ll need for most die-cut designs.

How to Calculate Tap Drill Size To Use

How to Calculate Tap Drill Size To Use

Tap-drill diameter equals nominal diameter minus thread pitch. For example, drill size for a 3/8-16 thread is 0.375 0.0625 (pitch) = 0.312 in.

What do tap and die sizes mean?

To compute, take diameters less than 1/4-inch are numbered according to the wire gauge sizes of machine screws. For example, a die marked 10-32 NF will cut threads for a No. 10 machine screw with 32 fine threads per inch.

What is the big difference between drilling and tapping?

Drilling and Tapping

Drilling is a process that uses a drill to penetrate through the surface of the rock. The more holes are drilled, the bigger the hole will be.

Tapping is a more controlled process that creates shallow cuts on top of the surface of the rock. This method is used when there is no drilling equipment available.

The drill is the process of drilling through the ground. Drilling is used for development purposes. The difference between the two is that drilling produces a hole in the ground whereas tapping does not.


A Metric Tap and Die Set Chart is a visual aid to help you determine the number of parts needed to complete a job.

The chart is based on the relationship between parts and tool sizes. Tap and Die sets and charts are the most versatile design tool available.

They allow you to get creative, change your mind, and get to work on an assignment without having to stop.
