A thread cutting die can be used to cut external metal threads. It is therefore the corresponding counterpart to the screw tap, which is used for cutting internal threads. The thread cutting die is usually made of high-speed steel, is cylindrical in shape and has several cutting parts with which the threads are cut evenly. Between these cutting edges are holes, so-called chip holes, through which the metal chips can roll off. Further holes for retaining screws are worked into the outer edge.
At thread cutting, the thread is first fixed before the thread cutting die is set at a right angle. Then it is turned - by hand or by machine - until the required total length of the external thread has been reached. Thread cutting dies are mainly used for pipes and lines that are required in the plumbing sector. To reduce wear during frequent use, we recommend using a cutting oil as a lubricant.
The common thread cutting die for standard threads are particularly popular for our customers, but we are equally large in the area of fine threads. Here we can offer you an enormous range of different tools designed for fine threads. This is mainly due to the fact that fine threads are used more frequently in certain areas, as they have decisive advantages.
Difference between metric regular and fine threads
Both metric threads are defined according to DIN 13 and have the same thread angle of 60°. The standard thread and the fine thread differ in the pitch, i.e. the distance from thread tip to thread tip. While the standard thread i.e. for M 10 always has a pitch of 1.5, fine threads can also have pitches of 0.5 / 0.75 / 1 or 1.25.
Advantages and disadvantages of the fine thread
Unfortunately, a fine thread is susceptible to contamination, defects or seizure. In addition, it is not suitable for high-speed assembly, as it quickly becomes wedged. On the other hand, it is stronger and ideally suited for precision connections.
The advantages are clearly the small thread depth, the narrow thread profile and the higher contact pressure. This means that products with fine threads can also be used in confined spaces. They are particularly popular in measurement technology.
Due to the higher self-locking, fine threads are ideal for critical connections that are exposed to vibrations or other high loads, for example. Fine threads can withstand more stress in most materials and enable a more stable connection. They do not loosen as quickly and can also be installed in hard materials. They also require less torque when cutting the thread.
Thread cutting dies for fine threads
Here you have the choice between different tap (hand taps, machine taps), forming taps, thread plug gauges and ring gauges as well as:
We stock both individual thread cutting dies and sets suitable for machining a wide range of materials.
Our thread cutting dies are ideal for general use on a variety of materials such as: Structural, free-cutting and case-hardened steels, unalloyed heat-treatable steels, copper, bronze or various plastics. The possible materials are explained in more detail in the respective product description.
In stock we have thread cutting dies according to DIN (tolerance 7e) and DIN 513 (tolerance 7e) in different dimensions, with which you can cut the most different external threads. Thread cutting dies according to DIN are metric buttress threads for fine threads and are available from us with a pitch of 0.8 mm to 1.5 mm. The metric buttress thread according to DIN 513 for general use is available with pitches from 2 mm to 3 mm. The two variants are suitable for general structural steels, case-hardening steels, unalloyed heat-treatable steels, pure copper and plastics, among others. In addition, we offer a thread cutting die according to Deckel standard 1.596.01. The special buttress thread is suitable, for example, for collets or sleeves on lid, tool and milling machines.
With us you will find a large selection of different screw taps and thread cutting dies for metric coarse threads and many other thread standards. We carry suitable sets from HSS thread cutting dies for normal applications in the Dimensions M3 to M12 - also for left-hand thread and stainless steels.
The thread cutting dies are suitable for these materials:
The sets for right-hand and left-hand thread are suitable for machining the following materials: e.g. for general structural steels, free-cutting steels or case-hardening steels, unalloyed heat-treatable steels, pure copper / low-alloyed copper, copper-tin alloys (bronze) as well as plastics (PMMA, POM, PVC).
The sets for stainless steels are suitable for machining stainless steels, difficult-to-machine materials up to N/mm² (the repair set up to 800 N/mm²) as well as for general use.

Have you also noticed the price differences when researching for a good thread cutting assortment? What is the reason that the thread cutting sets are either very cheap or perceived to be very expensive? Does a red metal cassette cost less than a blue or green one? Are the tools in the cassettes really all the same in terms of quality? What is the difference between WS and HSS tools?
Goto GSR to know more.
In this article, we want to get to the bottom of these questions and help you find the right threading assortment for you. Have fun reading!
Especially on the marketplaces like Amazon and Ebay, you can always find very cheap taps, dies or complete thread-stenoid assortments as well as sets. In the research, the pictures of the tools also all look the same or undercut only in the color of the cassettes. But the color of the cassettes can not explain the sometimes very high or low prices. Is it then due to the brand product? What is happening here?
The price differences may depend on the size of the set in the first step. Is it a 32-piece set or a 48-piece set? What thread diameters are covered in the assortment? What tools are all included in the set?
Most assortments cover the sizes M3 – M12. But there are also assortments up to M20 or also M24 or also inch thread types. Another difference is made by the holding tools, HSS twist drills, hand tap guides, die guides, etc.
It is important that you take a close look at the item description of manufacturers and dealers. This is because some dealers obscure the description so that you can’t necessarily tell at first glance what the tools are made of. Others use click-worthy keywords such as HSS drill bits in the article title. This is common practice on the relevant online marketplaces to list drilling as well as threading tools. In addition, it is very popular to write about HSS drills in the article description, which are not even included in the scope of delivery.
But what if the retailer or manufacturer does not even provide any information about this in the item description? If you want to be on the safe side, you should write directly to the manufacturer or dealer.
In the description of threading assortments, a closer look reveals the designation tool steel (WS) and high-speed steel (HSS). This is one of the main differences why prices vary so much.
Incidentally, this applies not only to the ranges but to all cutting tools, such as hand taps, machine taps, dies, drill bits, etc.
This is because taps made of tool steel are more suitable for re-tapping threads. Tapping of soft materials and low alloy structural steels is also well feasible with WS tools. However, you have to make concessions here in terms of thread tolerance.
With HSS tools, on the other hand, you can also cut threads in alloyed belly steels, free-cutting steels or even stainless steels.
Which set is better for you depends on the application. Do you cut rather infrequently and have to recut a thread in soft materials (plastic, aluminum, etc.)? Then you should take a look at the WS sets. Please note that the tolerance can be inaccurate here.
Do you frequently recut threads? Do you need an exact thread tolerance? Do you also want to cut threads in harder materials such as alloyed structural steels?
Then you should rather invest in a HSS thread cutting assortment. HSS threading tools are always more expensive and of higher value than WS tools.

Another price distinction arises when a threading tool is manufactured according to DIN standards. In this case, the tolerance is adhered to more precisely than in the case of tools manufactured to factory standards. Accordingly, DIN tools are somewhat more expensive, since higher quality is already assumed during production. Many manufacturers mark their tools with the DIN identification. If there is no marking, it is still very easy to recognize a tap or a die according to DIN by its workmanship. Pay attention to the shaping of the tip, the flutes, the profile and the run-out.
There are also significant differences in the outer packaging that influence the price. The wooden cassette is the most expensive variant here. Although these are very sustainable as well as optically very valuable, they are hardly offered, because a customer is not willing to pay the money compared to the cheaper metal and plastic boxes. On the various marketplaces you can find more and more assortments packed in plastic boxes and assortments in metal cassettes. The metal cassettes also differ in the material used and the sheet thickness. If the cassettes are manufactured and coated in Europe, they are correspondingly more expensive than if they come from other Asian countries.
The adjustable tap wrenches and die holders can also be manufactured according to factory standard or DIN. In addition, the manufacturing process plays a major role in the body as well as the toggles of the holding tools.
How can you recognise a good adjustable tap wrench?
Essentially, the new tools holders have a different body geometry that results in higher torque. If you take a closer look at the adjustable winch, for example, you will immediately notice the honeycomb shape on the handle holder. Another important point is the material used in the base body. Because not all zinc die casting is the same. The holding tools with honeycomb shape geometry always have the zinc die casting alloy Zamak-5 (EN ).
GSR Gustav Stursberg is the only manufacturer and supplier of these unique tool holders.
The price differences have primarily to do with the quality of the tools. When deciding on a purchase, you should therefore know beforehand for what purpose you need the tools. Is a thread only to be recut? Then the purchase of a WS thread cutting assortment in red or green cassette is sufficient. Do you only cut two threads in aluminum or zinc once a year? Then a WS set is also sufficient. But still pay attention to the quality of the tool! There are very many WS quality levels.
Are you an ambitious professional craftsman or metalworker? Do you cut threads often? Do you machine all kinds of materials from aluminum to quality structural steels, such as ST52, to stainless steels like ? Do you want to have fun with thread cutting?
Then we definitely recommend you to buy an HSS thread cutting assortment in a gray industrial cassette according to DIN.
The same is true for the individual threading tools. The more demanding and precise the project, the more you should rely on HSS manufactured tools.
