12A2 Diamond Wheels

Product Overview

Braemar USA’s 12A2 Resin Bond Diamond Wheels are designed for precision grinding of carbide, ceramics, glass, quartz, sapphire, and advanced technical materials. The 12A2 dish profile provides controlled access for edge shaping, relief angles, and complex geometries. In addition, the resin bond system supports cool-cutting, low-force grinding with predictable wear behavior.

Wheel Geometry (12A2 Shape)

• Dish-style profile with relieved center

• Angled grinding rim for improved access

• Rigid structure for tight tolerance applications

• Supports end gash grinding, relief work, and profile shaping

Bond System – Resin Bond

• Cool-cutting action for reduced heat

• Lower grinding forces on brittle substrates

• Controlled diamond exposure for self-sharpening

• Stable surface finish across long grinding cycles

• Reduced risk of burning or micro-cracking
