FANAR MASTERMILL R440N Solid Carbide End Mill 8mm with 0.5mm Corner Radius, 4-Flute, TiAlN-Coated, 19mm Cutting Length, 63mm Overall Length

With a 45° helix angle and h6 tolerance on both cutting and shank diameters, this FANAR MASTERMILL R440N end mill delivers precision in high-performance machining of hardened steels up to 60 HRC, stainless steels, cast iron, and exotic alloys. The TS coating—a high-performance TiAlN-based layer—enhances wear resistance and thermal stability, ensuring extended tool life even under demanding conditions.

Overview

The FANAR Carbide End Mill FI 8.0 R0.5 19/63 Z4 HA8 VHM TS R440N MASTERMILL is a solid carbide (VHM) cutting tool engineered for high-speed, high-feed milling operations. Its 8.0 mm cutting diameter, 0.5 mm corner radius, and 4-flute design provide an optimal balance between chip evacuation and surface finish. The cylindrical HA shank with 8 mm diameter ensures secure clamping and concentricity in standard collets and hydraulic chucks.
