JMD10
Features: Characterized by irregular, sharp crystals with relatively high impurity levels, this diamond exhibits excellent brittleness, strong self-sharpening ability, and an incomplete crystal structure that enhances retention.
Applications: Ideal for resin- and ceramic-bonded tools requiring extended service life, as well as low-demand electroplated tools. Widely used in machining steel, hard alloys, magnetic materials, polishing ceramics and stone, jewelry setting, dental grinding, and rubber sheet cutting.
