KOMET  DIHART®  MicroSet System

Reaming with adjustable inserts

The new reamers from  KOMET®  which boast individually adjustable inserts are an alternative to the ready-to-use ground tool variants. These reamers also feature multiple blades and offer maximum flexibility, reduce logistics with regard to retipping and enable cost savings thanks to the favourably priced inserts which are available from stock. The single-blade inserts are screwed in place and setto a diameter and tapering using a newly developed fine adjustment system for indexable inserts with μm accuracy. This makes hole tolerances of M IT5 easily achievable. The reference dimension is provided by two measuring blocks. Only 14 inserts for the diameter range of 40 to 140 mm. Maximum flexibility in terms of fields of application, availability and variety of cutting materials and coatings are features of this tool, because certain components, tolerances, volumes, etc., often determine which combinations are used.



  • Diameter range of 40–140 mm
  • Hole tolerances of ≥ IT5
  • Applications in casting, solutions for steel, stainless steels, aluminium and other materials follow
  • The tool concept can be used in special and stepped tools


Benefits to you

  • Maximum flexibility
  • Reduces logistics with regard to retipping
  • Cutting inserts available ex stock
  • Individually adjustable cutting inserts
  • Easy to handle when adjusting and replacing the cutting inserts

Precision and productivity

Even when the demands on a component are particularly high and the highest precision is required, the  KOMET  DIHART®  MicroSet system gives you a special advantage: The tools can be readjusted at any time. All that needs to be done is to readjust the indexable inserts in the precision adjustment system to the required diameter. Only when the cutting edges are worn do they need to be replaced.

The special strengths of the  KOMET  DIHART®  MicroSet system can truly be seen when used with special tools, especially with stepped tools that the user can design themselves. Thanks to the variety of possible combinations, the user can quickly put together a reaming tool that is ideally suited to the component with regard to its materials, tolerances and volumes.

The MicroSet tool shown uses this advantage perfectly and meets the application requirements better than the previously used brazed PCD tools. An inability to correct the brazed PCD inserts, particularly in the second stage, results in operating times of different lengths and erratic repairs.

Having the standard indexable inserts available ex stock (tipped with PCD in this case) eliminates long repair cycles and increases not only the flexibility of the system but also the productivity and the profitability of an application.
