PCD Bottom Radius Form Milling Cutter – Model PCD-FMC-BR | Aoshiji® Custom Tool
Overview
The PCD Bottom Radius Form Milling Cutter (Model PCD-FMC-BR) is engineered for high-precision profile milling where a defined bottom radius (R-corner) is required. Manufactured with polycrystalline diamond (PCD) cutting edges, this tool delivers superior wear resistance, extended tool life, and mirror-like surface finishes in non-ferrous materials and composites. Optimized for high-speed CNC machining, it maintains tight dimensional control on radius features while ensuring smooth chip evacuation.
Applications
Precision form milling with bottom radius geometry
Automotive and aerospace components requiring radius-controlled features
Mold and die machining with bottom corner R-profiles
High-speed machining of aluminum, magnesium, composites, and plastics
Custom radius forming: R0.2 – R5.0 or per drawing
Key Features
Defined bottom radius forming – Produces accurate R-corner geometry for higher part quality
PCD cutting edges – Maximum wear resistance and superior edge integrity
High accuracy – Maintains tight tolerances on form and radius geometry
Custom geometry – Flute count, shank style, and R-size tailored to specifications
Optimized chip flow – Stable performance in high-speed machining
Benefits
Improved form accuracy and dimensional consistency
Extended tool life compared to carbide or HSS alternatives
Reduced cycle time with fewer tool changes
Lower cost per part in mass production
Superior surface finish, reducing polishing or secondary finishing
