Brazed Diamond Grinding Pin with Vacuum Brazed Synthetic Diamond D80/100 Grit

Brazed Diamond Grinding Pin for Superior Wear Resistance Carbide Stone Glass Precision Grinding

The Brazed Diamond Grinding Pin is a high-performance mounted point engineered with vacuum-brazed synthetic diamond abrasive (D80/100 grit) on a precision-ground steel shank, delivering exceptional wear resistance and extended tool life for carbide, stone, glass, and ceramic grinding applications. Unlike electroplated diamond tools where abrasive particles sit on the surface, the vacuum brazing process creates a metallurgical bond that embeds diamond grains deep within the bond matrix, providing 5-10x longer service life and preventing catastrophic grain loss during heavy grinding operations.

Key Features

• Vacuum Brazed Diamond Abrasive Bond: Premium synthetic diamond particles (D80/100) are permanently fused to the steel substrate through a high-temperature vacuum brazing process. This creates a metallurgical bond far stronger than electroplated or resin bonds, ensuring diamond grains remain firmly anchored even under extreme grinding forces. The deep grain embedment means fresh diamond cutting edges are continuously exposed as the bond matrix slowly wears, delivering consistent material removal rates throughout the tool's full service life.
• Superior Wear Resistance: The brazed diamond bond eliminates the primary failure mode of conventional diamond tools—premature grain pull-out. Each diamond particle remains firmly embedded until fully consumed, maximizing abrasive utilization and delivering 5-10x longer tool life compared to electroplated diamond mounted points. This dramatically reduces tool change frequency and per-part grinding costs in production environments.
• Precision Surface Finishing: The D80/100 diamond grit combined with the R12.7 nose radius provides an optimal balance of material removal rate and surface finish quality. The precisely formed half-sphere tip geometry enables accurate profile grinding on complex carbide tool geometries, stone edge profiling, and glass bevel finishing with consistent results from first use to last.
• Multi-Material Versatility: The brazed diamond abrasive excels across diverse hard materials including tungsten carbide, engineering ceramics, natural and engineered stone, optical glass, and composite materials. The aggressive diamond cutting action with minimal heat generation makes this pin ideal for dry and wet grinding applications alike.
