Sumitomo Electric Hard Metal Sumidia Binderless Ball End Mill

Although it is made of 100% diamond, it does not have the anisotropy of single crystal diamond, so it exhibits less uneven wear and excellent wear resistance.
Due to its polycrystalline structure, it does not have the cleavage characteristic of single crystal diamonds and has excellent chipping resistance.
The cutting edge is made of nano-polycrystalline diamond, which is harder than single-crystal diamond.
It enables direct engraving of cemented carbide, which was not possible with existing single crystal or polycrystalline diamonds.
Ideal for finishing hard and brittle materials such as cemented carbide, achieving high precision machining and a long tool life.
Standard finish NPDBS type significantly reduces processing costs.
For finishing of cemented carbide and hard brittle materials.
