Fixed diameter honing tools - easy application, perfect diameter

Fixed diameter honing tools are high-precision, very sturdy honing tools for honing in diameter ranges of 6mm to approx. 100mm. 

Fixed diameter honing tools have preset diameter and machine (ream hone) a bore with a one-time in-and-out movement (double stroke). Different honing allowances can be achieved in the different operations depending on the tool design and surface requirements. 

The fixed diameter honing tool guarantees the best possible correction of roundness and bore size, especially for interrupted bores (such as hydraulic housings or valve manifolds). 

Fixed diameter honing tools are especially well-suited for milling centres, turning centres or general machining centres and are designed in different shapes for each specific application. 

  • Ream honing in diameter ranges from 6mm to over 100mm 
  • Honing stone mounted on the base body of the tool
  • Tools are produced with all conventional connections (e.g. HSK, collet, hydraulic chucks, floating chucks, etc.)

Our application engineers establish the appropriate tool principle depending on part geometry and bore requirements. For queries please contact werkzeug(at)
