RP, RK, RKA: Non-cylindrical surfaces, plane surfaces and cones (internal and external)


  • Applied force of tool in axial direction
  • Can be used in almost all machine tools
  • Either the tool or the work piece rotates depending on the type of machine
  • Processing of all metallic materials with a tensile strength of 1400 N/mm2 and a maximum hardness of HRC = 45

3D-View RKA



  • Reliable function; high precision
  • Large range of contours and combinations of diameters available
  • Economical due to extremely short primary processing time
  • Consistent machining results through optimum spring characteristics
  • Tool shanks available for all clamping systems
  • Simple replacement of wear parts

Basic construction

  • Tools are usually equipped with Morse taper, but can be fitted with cylindrical shanks to DIN 69880 (VDI shank) or shanks for other clamping systems. 
  • Lamination of the springs is optimally designed for each individual machining task. 
  • The roller head is specially matched to the dimensions of the work piece and purpose built.
