SRDM – Surface Roughed Diamond Micropowder
20+ Years Experience
Ultra-Precision Quality
Customized Solutions
SRDM is a surface-roughed diamond micropowder engineered for electroplated tools and high-hold-force bonded systems where strong grit retention and long tool life are critical. Through controlled surface etching, each diamond particle develops a micro-pitted texture that enhances mechanical interlocking with binders while preserving core crystal strength, resulting in stable cutting performance and a smoother scratch profile in precision grinding and polishing applications.
