Tool solutions for renewable energies and traditional petrochemical industry



Renewable energies or classic petrochemicals - wind power plants, turbines or pipelines, we offer the right tool solutions to process the high-tech materials used and we have tools that are specifically tailored to the requirements of energy technology.

The materials used are mainly high-strength steels, aluminium and AlSi alloys, cast materials and fibre plastics.

Manufacturers of turbines have particularly large threads to produce, SPPW offers thread milling cutters that can reliably insert these threads into turbine materials.

For the production of rotor blades in wind power, we have solutions for processing fibre plastics and at the same time also the fillers used such as foam or honeycomb.

For the production of the connection of the individual components, i.e. rotor blade, hub, drive, gear, nacelle and tower, we offer a wide range of high-precision cutting tools for drilling, reaming, thread milling or deburring. They all create high-precision and burr-free surfaces so that assembly can be carried out without any problems.

We have special thread milling cutters and thread turning tools in our range for manufacturers of pipelines and pipelines, which comply with the relevant standards and can be used, for example, for the manufacture of self-sealing threads.

This also includes innovative solutions such as our micro milling cutters, which are used in the manufacture of fuel cells.


Self-sealing threads are required especially for pipelines and applications in the chemical and petrochemical industries.

Autoseal Threading Tools 



With this new generation of thread milling cutters it is possible to produce burr-free threads of high quality without previous chamfering and at the same time to manufacture the thread entrance. Deburring takes place automatically during thread milling.

This means a considerable time saving in production. Lower tool costs due to multiple use of one tool for different thread types round off the picture.

In addition, almost all materials, even those that are difficult to machine and high-strength, can be reliably machined.


The cutting length is indicated on the thread milling cutter and can also be found in the catalogue. The indicated length is the distance from the top of the workpiece to the bottom of the thread, including the deburred thread entrance.


  • For through holes

any standard Threadburr can be used, simply drive the tool so far into the hole that the deburring can be done. However, we always recommend using short thread milling cutters.



  • More tool life
  • Less runtime
  • Better surface finish
  • Fewer tools
  • burr-free thread
  • More process reliability



  • For blind holes

the thread milling cutter must correspond to the thread depth in order to also deburr. We offer various cutting lengths from 1.5xDC to 3xDC as standard. If no suitable length is available, we will shorten your cutter accordingly. Please note that the cutting length corresponds to the thread length plus 1 gear and that the cutting length must be divisible by the pitch.



Example :

M16x1.5 Thread length 24mm

ThreadBurr NB1212D2915ISO - cutting length of 29,25mm

24 + 1,5 = 25,5mm required cutting length incl. deburring step
29,25 -25,5 = 3,75mm Length to be shortened
3,75 / 1,5 = 2,5P

Number of threads to be shortened

2 x 1,5 = 3,0mm length to be shortened (multiple of P)
29,25 – 3,0 = 26,25mm Cutting edge length after shortening
26,25 – 1,5 = 24,75mm Resulting thread length


If you do not want to use the deburring function, you do not have to shorten the thread milling cutter.



With Twin-ThreadBurr, both sides of a thread can be deburred with plate material. This makes it possible to produce burr-free threads with deburred thread entry and exit. For this application we manufacture a special tool for you, as the distance between the two deburring steps depends on the thickness of your panel material.



M30x3 with thread length 40mm

40 / 3 = 13,3 Number of threads
13 x 3 = 39,0 mm Thread length


The required Twin-ThreadBurr (NBB2020D3930ISO) has a thread length of 39 mm, which includes the 2 deburring steps.



Fibre (reinforced) plastics are regularly used in the manufacture of rotor blades for wind turbines in order to save weight. They consist of the fibre (glass or carbon) and the plastic matrix, often epoxy resin. GRP and CRP are often used in combination, CFRP especially for stiffening, GRP for the rest of the structure, since GRP is the much cheaper material. This allows large parts to be produced without any problems. The GRP fibres are often disordered, while the CFRP fibres are oriented.

-> SPPW GRP milling cutters have a pyramid-shaped toothed cutting edge and are often coated with Dia.HC. The cutting edges are available in fine, medium and coarse profile shapes as well as different face geometries for the respective application. SPPW CFK milling cutters have many cutting edges with chip breakers and are Dia.HC or diamond coated.
Cutters with alternating spiral direction avoid delamination.


Honeycomb composites (WV) are used to improve the structural strength of rotor blades with the aim of reducing weight.
Alternatively, foams can also be used as filler materials.
Machining with normal tools is not possible as the honeycombs are crushed and cannot be cut. Honeycomb residues remain which have to be removed by hand.

-> SPPW Honeycomb milling cutters, also known as choppers or hoggers, have an extremely large number of small, spiky blades that divide the honeycomb structure and then peel it off.


Due to their high hardness, hardened steels are mainly used in mechanical engineering for wear parts.
Most hardened steels have hardnesses up to 54 HRc. They are mainly used for plastic injection moulds and in mechanical engineering.
Steels with hardness up to 62 HRc are mainly used for forming tools and heavy-duty machine parts, as well as for injection moulding of fibre plastics.
Steels with hardnesses above 62 HRc are used in the manufacture of tools for cold and hot forming, in toolmaking for spindle bearings, valves or other heavily stressed parts.
The focus is on tool life, high process speed and precision.

-> Most SPPW tools are designed as universal tools, i.e. suitable for machining a wide range of materials. We recommend the use of coated tools for steel machining. A suitable cutting material must be selected depending on the hardness of the material. From a tensile strength above 30 HRc (1000 MPa) we recommend the use of VHM tools, above 45 HRc only coated tools and for hardnesses above 54 HRc suitable special geometries.


Aluminium alloys (Mg, Si, Cu, Zn)
are very different in their machinability. For example, Al6061 is difficult to machine while Al7075 (AlZnMgCu1.5) is easy to machine.
Depending on the alloy, microstructural changes may occur during storage which cause changes in strength.

-> SPPW aluminium milling cutters have large grooves for optimum chip removal and between 1 and 3 cutting edges.
The cutter surfaces are often polished and coated (Dia.HC, Alu.Cut, Z.Cut) to prevent weld build-up.
