What is formtapping?
For many engineers, the concept of “Form” tapping or cold forming can be a stumbling block in itself, simply because it is an entirely unfamiliar way of producing a thread.
Forming taps however provide multiple advantages. For ductile work materials, thread forming can provide better size control and stronger threads while improving tool life and productivity.
Unlike thread cutting, no material is removed during thread forming. Rather, the process displaces the material to generate the thread form.
Since the metal's structure is cold worked along the thread profile, the threads produced are generally stronger and have a smooth, burnished surface finish. Cold forming taps can be operated at higher speeds and feeds than conventional taps.
Cold forming technology has been used to produce threads for more than 100 years. Tap designs have changed considerably in that time. This combined with the newest coatings guarantees a very long tool life in most applications.
Forming taps must be applied in materials that cold form well. This includes steels, stainless steels, light metals, light metal alloys and other materials with tensile strength to 1200 N/mm². Generally, materials that produce a continuous chip when drilling are good candidates for thread forming.
In combination with Formdrill, thread forming will boost quality and throughput.

An extremely versatile range of Roll Form - or Forming - Taps, each of which can be used for producing both through and blind holes. Designed to accurately and cost effectively produce an internal thread by deformation of the component material, this process produces no chips, resulting in a stronger thread that is capable of withstanding increased load-bearing capabilities. They can also be operated at higher speeds than conventional thread cutting taps, resulting in increased productivity:
- HSS Roll Form Taps
- HSCo Roll Form Taps
- Solid Carbide Roll Form Taps

Our roll forming taps (Flowtaps) are made of high quality high-speed steel and can be ordered with lubrication grooves and coatings for special applications. The square shaft at the end is optimally designed to transfer the required torque to form the threads.
Flowtaps are available in
- American Standards
- Pipe Standard
- Metric Standards
Lubrication grooves and special coatings are also available

The ECO thread former Protodyn Cap from Walter Prototyp has been developed to guarantee optimal internal coolant supply. The innovative, front face radial coolant outlets mean the tool has a higher degree of stability in comparison to conventional thread formers with internal cooling.
ECO thread former Protodyn CAP
Significantly increased tool life in terms of external coolant supply, particularly with greater thread depths.
Equally suitable for use in blind and through holes.
Optimised for wet machining, but minimum quantity lubrication is also possible.
Greater tool life due to the TIN-coating that has been specially modified for thread formers.
The HSS-E thread former PROTODYN S Synchrospeed has been specially developed for use in machines with synchronous spindle. The tool is particularly suitable for producing threads in all ductile materials with a strength of up to 1200 N/mm² or at least 10% expansion.
Synchrospeed-thread former Protodyn S Synchrospeed
Universal use (through holes and blind holes)
High tool life through HSS-E
High accuracy to gauge thanks to pointed polygon profile
High process reliability thanks to short thread component and special geometry
High degree of efficiency thanks to special surface treatment

Thread forming with centertap offers the exact same advantages as flow punch forming. It is a chip- less process in which the material is rendered flowable and displaced from the thread root into the crests. It is similar in principle to the rolling of external threads. centertap is available for all common thread sizes.
Advantages of Thread Forming
Non-cutting manufacturing process
Reinforced orientation of the material fibers results in threads that can withstand high drawing forces
Highly accurate threads, therefore miscutting is not possible
Low wear after multiple connections due to increased hardness
3 to 10 times faster than thread cutting
Increased life due to special TiN coating
Reduced friction, less burr formation and scoring
Can be automated

Always in Top Form with EMUGE InnoForm
With the publication of the new EMUGE Catalogue 130, EMUGE became
the first threading tool manufacturer worldwide to introduce a programme
of cold forming taps specially designed for the machining of specific materials or material groups. While this was common only for cutting
tools in the past, we have now succeeded in designing cold forming
taps especially for the special properties of single material groups,
partially increasing performance in a dramatic way.
Conventional cold forming taps were made for the use in all ductile materials: potential performance features in defined applications were simply wasted
in the process.
EMUGE has made painstaking investigations into the mechanisms of cold
forming, and developed a perfectly new tool generation from the results.
With 7 basic geometries, all of them available in different designs, we
want to make sure that performance can be increased noticeably.
