1A1 CBN Wheels are engineered for precision grinding of hardened steels, high-alloy tool steels, and ferrous materials where heat control, surface finish, and edge integrity are critical. The 1A1 flat-profile wheel design delivers exceptional rigidity and stability, making it ideal for surface grinding, cylindrical grinding, OD/ID grinding, and high-accuracy tool manufacturing.
Built using premium synthetic CBN abrasives and advanced resin bond systems, these wheels provide a fast, cool-cutting action that maintains sharp cutting edges throughout the wheel’s life. Braemar USA’s resin matrix is formulated for controlled breakdown—continuously exposing fresh CBN grains for consistent performance, reduced heat, and superior surface quality.
CBN is the optimal abrasive for ferrous materials because it will not chemically react with iron.
Braemar 1A1 CBN wheels excel in grinding:
High-speed steel (HSS)
M2, M35, M42 cobalt steels
Tool steels (D2, A2, S7, O1)
Powder-metal steels
Bearing steels (52100)
Heat-treated alloy steels
Nickel-based alloys
