Metal Wheel for Super-Hard Main Groove Grinding “Dress-less Metal (MDL)”

Machining the main grooves and gashes of round tools requires deep cutting and produces a lot of heat. As a result, resins with low heat tolerance will soften and lose their abrasiveness, becoming unable to cut.
Metal, on the other hand, has high heat tolerance and can retain its grain, but often exhibits poor initial cutting performance because of poor dressability.
Dress-less Metal offers the high performance of metal with the dressability of resin, making highly efficient machining easy to perform.


  • Dress-less Metal offers the same heat tolerance and high grain retention as other metals, so it keeps its sharpness well and exhibits less wear, enabling highly efficient machining with longer adjustment intervals.
  • Dress-less Metal has good dressability on par with resin, exhibiting good sharpness from the start and enabling highly efficient machining.


Ideal for grinding grooves and blades for super-hard drills, cermet drills, and endmills.
