12A2 CBN Wheels
12A2 CBN Wheels Resin Bond are engineered for precision grinding applications that demand exceptional edge stability, cool-cutting performance, and superior surface finish on hardened steels and high-alloy materials. The 12A2 profile features a dish-shaped, reinforced structure that provides excellent rigidity and clearance—making it ideal for sharpening, tool room grinding, jig grinding, and profile grinding of ferrous materials.
Built with premium CBN abrasive and advanced resin bond matrices, Braemar 12A2 wheels deliver clean, fast cutting with reduced heat generation, minimal burning, and consistent form accuracy across long production runs.
Key Features & Performance Advantages
Optimized for Hardened Steels & High-Alloy Metals
CBN is the abrasive of choice for ferrous materials, delivering unmatched grinding efficiency on:
High-speed steel (HSS)
M2, M35, M42 cobalt steels
D2, A2, S7 tool steels
Powder-metal steels
Bearing steels (52100)
Heat-treated alloy steels
Nickel-based superalloys
Resin bond holds the CBN abrasive securely while providing controlled breakdown to expose new, sharp cutting edges.
Cool-Cutting Resin Bond Technology
Braemar’s resin bond system provides:
Lower grinding forces
Reduced heat and burning
Smoother cutting action
Longer wheel life in precision environments
Excellent surface finish with minimal micro-fracture
These characteristics make the 12A2 ideal for grinding delicate geometries and heat-sensitive tool edges.
