Now, you must not sway yourself by the eloquence of the sellers. Learn the ropes of buying a tap and die set and choose a top-notch one yourself. We are here for you to go into deep analysis to help you get to the best one regardless of whether you are a pro mechanic or DIY user.


Tap and Die Set buying guide

Whether you are a pro or a home user, you have to have the knowledge of appropriation when it comes to buying a tap and die set. Knowing what would be best is never easy. That is why proper study material is required. This is where we come to help you become familiar with the yes’s and no’s of a tap and die set.


Construction Quality

Carbon steel always has the upper hand in terms of strength. Next comes alloy steel with the additional advantage of less price but compromising durability. Having checked them, go for coated materials since corrosion and rust are common foes you’ll find while dealing with nuts and bolts.

Diversity of Parts

Focus on the sizes of the dies and taps your field of application requires. Getting more parts expending the same often means the lower material quality or misaligned cuts. So no need to hanker after multifarious kits if smaller ones suffice your project. The money would worth the most by grabbing a set featuring a variety of ratchets.

Size Measurement System

The size of the taps and dies are defined by two types of measurement systems- metric and SAE. Metric is the European measurement system while SAE characterizes the US measurement system. A set where both of the systems are available surely packs a punch.

Part Count Inflation

Many manufacturing companies will include extra parts like screwdrivers and nut drivers to inflate the part count. If you really need that extra piece, it’s recommended to buy that separately.  But if you seldom have its usage, you may go for it if the price is within budget.

Tap variety

The varieties of taps you will come across while buying a set are- taper, bottoming and plug types. You will at most get two of these types in a set, but not all. Taper taps make it easier for you to start threading as they require the least force.

Bottoming taps are on the other side of the pole as they are much harder to start for beginners. But the threads that will be produced will be of high quality. Plug taps combine features from both of the other two taps. They feature tapered threads at the beginning but not as easy as taper taps to start.


A wrench helps you hold the tap rigidly and distribute forces equally while threading. During tapping, a certain procedure may invoke chances of snapping. Ratchet wrenches help the most as they allow to make reversing even in confined places. But to get top tier premium quality end products, buying separate wrenches would be the finest option


Lubricants are a must for metal cutting operations. Lubricants like oil, water or wax deliver quick removal of chips and protect the parts from quick wear and tear. They play a vital role in lengthening tool life. Always make sure you use the right amount of lubricant before the start of threading or other cutting operations.

Storage Case

The storage and carrying cases are usually made of plastic or metal. Metallic ones increase bulk but are profoundly manufactured to fit the tools into places. On the other hand, plastic made storage cases are light and easy to transport. If your workplace is too jammed with sharp objects, even cumbersome metal storage should be the best choice.

Frequently Asked Questions

Here are some frequently asked questions and their answers.

What can you do with a tap and die set?

Taps and dies are tools used to create purpose screw threads, which is called threading. 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).

What do the numbers on a tap and die set mean?

Taps and dies with 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.

Who makes good quality taps?

Bathroom Taps are what we are known best for, here you will find the most reputable brands of mixer taps available in the UK including Bristan, Crosswater, Hudson Reed, Ultra and Roper Rhodes with newer exciting brands like Flova Uk, all made from the highest quality materials.

How do I choose a tap?

What is the first tap to be used when tapping?

When processing threads with machinery, -Plug taps are commonly used for through hole tapping with metal working machinery without using a starter Taper tap. -If using metal working machinery, you can start blind hole tapping with a bottoming tap without using a Taper and Plug tap first.

Which tool is used to turn taps?

tap wrench
A tap wrench is a hand tool used to turn taps or other small tools, such as hand reamers and screw extractors.

How do you use tap die?

Why the hand taps are chamfered at the lead?

The primary purpose of the chamfer is to allow the first few cutting teeth to make progressively deeper cuts. This reduces the force the user requires in order to spin the tap as well as reducing wear on the tool. It also acts to help align the tap within its pilot hole.

What is bottoming tap?

: a hand tap cutting a full thread to the bottom of a hole.

Does a tap cut external threads?

External threads, such as for bolts and studs, are made by using a tool called a DIE, which is applied to a specific diameter of rod for the size and pitch of the threads you want to cut. Both taps and dies can be used to either cut new threads or repair damaged threads.

Why do taps break?

Usually if a tap breaks going in, it’s a lack of chip room below the tap. Helical flute taps or open holes will cure that. But braking on the way out is nearly always the flute being full of a long corkscrew chip, and trying to back out of the hole with that chip still in the flute.

How do you read a tap size?

Example: 1/4 – 20NC The 1/4 represents the diameter of the thread in inches. The 20 represents the number of threads per inch or TPI. Standard taps are either standard coarse series threads NC (1/4-20), fine series threads NF (1/4-28) or extra fine series NEF (1/4-32).

Can you hand tap stainless steel?

Stainless steel possesses a few other traits that affect the way it should be drilled and tapped: … They “give” or yield to a drill’s pressure before the tool’s cutting edges can gain purchase. This makes it difficult for the tool to break off chips.

Q; Can I use a tap and die set to remove a broken bolt?

Ans: Yes, you can. First, you need to drill the hole using a drill bit. Later you use a tap and cut into the bolt. Finally, use a lubricant and start drawing the bolt out.

Q: What is the measuring criteria for taps?

Ans: The Strength of a tap depends on the number of flutes. Thread size is usually measured along the length of the tap.

Q: Can stainless steel be tapped?

Ans: You will need high-speed steel tools to cut through stainless steel. But HSS tools are not much available in the market.


Bringing a sledgehammer to crack a nut is not going to get you anywhere. Your damaged tool is made of light material but you use a set of taps and dies made from high carbon steel on them, that would be a waste.
