Carmex Solid Carbide Double Radius Cutter - 4 Flute - 8.5mm x R1.5

The Carmex Solid Carbide Double Radius Cutter is a precision end-mill designed for radius filleting on a wide range of materials. With an 8.5 mm diameter and a 1.5 mm radius (R1.5) in a double-radius geometry, this 4‑flute cutter delivers consistent, smooth fillets and reliable edge quality on complex contours. It uses a cylindrical DIN 6535-HA shank and a next-generation PVD-coated ultra-fine carbide grade, delivering exceptional hardness, toughness, and wear resistance for demanding machining.

Built for engineers, machinists, hobbyists, and production shops, it offers straightforward setup, dependable performance, and predictable results in everyday milling tasks.

• Double-radius geometry for precise, smooth fillets: Delivers clean, accurate radii on complex contours, reducing post-processing and improving part fit.
• 4-flute solid carbide with advanced PVD coating: Combines efficient material removal with high edge stability and wear resistance for longer tool life, even in tougher materials.
• DIN 6535-HA shank for secure, repeatable seating: Standardized cylindrical shank ensures reliable clamping, easy tool changes, and compatibility with a wide range of holders.

This cutter helps you streamline milling workflows by producing consistent radii on the first pass, minimizing finishing steps and rework. The hard, tough carbide and protective coating resist wear, so you can rely on repeatable performance across jobs. With easy setup and secure clamping, you’ll experience less downtime and faster throughput in daily milling tasks.
