1. ANSI / ISO Code Breakdown
FBN: Manufacturer grade prefix identifying the specific Solid PCBN formulation optimized for high-speed machining.
R (Shape): Round profile, which maximizes edge strength and allows for variable depth of cut.
N (Clearance): 0° negative relief angle, giving the insert a robust structure to withstand high cutting forces.
M (Tolerance): Medium precision tolerance class standard across heavy-duty turning and milling inserts.
12 (Size): Inscribed Circle (IC) of 12.70 mm (equivalent to a 1/2" ANSI size).
04 (Thickness): Thickness of 4.76 mm (equivalent to 3/16").
00 (Radius): Full round profile (the entire perimeter functions as a continuous radius without localized corners).
2. Technical Characteristics
Substrate Material: Solid PCBN instead of a tipped or brazed corner format. This allows the user to rotate the entire round perimeter to access dozens of fresh cutting positions.
Thermal Performance: Retains extreme structural hardness at elevated operating temperatures exceeding 1,000°C. This enables dry machining workflows by converting intense cutting friction into chip softening heat.
Surface Finish Capacity: The naturally large radius acts as a built-in wiper edge, resulting in superior surface finishes that can eliminate the need for subsequent industrial grinding processes.
3. Industrial Applications
Workpiece Types: Hardened steels (50–64 HRC), high-chromium cast irons, hardened tool steel dies, sintered powder metals, and heat-treated automotive parts.
Target Components: Large industrial brake discs, bearing races, automotive transmission gears, heavy-duty pumps, rolls, and stamping dies .
