Richards RCH-0.075-1/8-4F-CARBIDE-EXT End Mill

Richards RCH-0.075-1/8-4F-CARBIDE-EXT End Mill is a solid carbide milling cutter with a 0.075-inch cutting diameter and a 1/8-inch (0.125") shank, configured as a four-flute end mill. Crafted from carbide, this tool combines hardness and wear resistance to support precise milling operations and consistent edge life under appropriate cutting conditions. The model designation places it in Richards’ RCH line of carbide end mills, with the EXT suffix indicating an extended-length variant within that family. The four-flute geometry provides a balance between chip evacuation and material removal efficiency, helping to maintain stability and finish quality on small-diameter profiles. This end mill is suitable for precision contouring, pocketing, and profiling tasks where a compact cutter must navigate tight radii and confined features, making it a practical choice for small-scale machining, prototyping, and instrument-grade components where exact tolerances matter. In use, this cutter would typically be selected when a small-diameter carbide option is required to achieve clean, accurate profiles in suitable materials, while offering the rigidity and wear resistance characteristic of carbide tooling.
