SHARPRO Ball Nose End Mill 4mm AlCrN Coated

Description

Product Overview

The SHARPRO ball nose end mill is engineered for precision CNC milling of a wide range of steels and cast irons. Featuring a 4mm diameter ball‑nose tip with an error margin of less than -0.02mm, the cutter delivers exceptionally smooth surface finishes. The tool is coated with AlCrN, a heat‑resistant ceramic layer that maintains cutting stability at high temperatures, reducing wear and extending service life. Constructed from high‑grade carbide, the end mill offers rigidity and durability for demanding machining operations. Model SPMB3200-2BS-1/8 complies with industry standards and includes a unique serial code for full traceability.

Usage

Designed for CNC milling machines, machining centers and conventional milling equipment, this ball nose end mill excels in plunge cuts, 3‑D contouring and complex geometry creation. It is ideal for fabricating molds, aerospace components, automotive parts and precision tooling where tight tolerances and fine finishes are required. The cutter performs consistently on alloy steels (HB 125‑430), stainless steels (HB 200‑300) and various cast irons (HB 155‑265), making it a versatile choice for manufacturers and prototypers alike.
