ACCUCUT 3/16″ Carbide Square End Mill 4 Flute AlTiN Coated 45° Helix

Description

Product Overview

The ACCUCUT I4KES 3/16″ carbide square end mill is engineered for demanding machining environments where precision, speed, and durability are paramount. Constructed from European‑origin ultra‑fine grain carbide, the tool offers exceptional hardness and wear resistance. Its 4‑flute geometry, combined with a 45 degree helix, enables rapid material removal while maintaining a smooth surface finish. The AlTiN coating, applied at temperatures between 450°C and 475°C, provides superior oxidation resistance and lubricity, extending the life of the cutter even under high‑temperature conditions. With a 3/16″ diameter, 15/32″ cutting length, and a 2″ overall length, this end mill fits standard CNC routers and milling machines, delivering consistent performance across a range of metals including steel, forge steel, copper, and various alloys.

Usage

This square end mill excels in applications that require precise planar, step, groove, and forming operations. It is ideal for machining HRC materials below 50, making it suitable for pre‑hardened steels, stainless steels, and copper alloys. Whether you are producing aerospace components, automotive parts, or intricate molds, the cutter’s robust design ensures reliable performance. The tool’s 4‑flute configuration reduces chip load, allowing for higher feed rates without sacrificing accuracy. Users in manufacturing, prototyping, and repair shops will appreciate the tool’s versatility and the consistent finish it delivers across diverse workpieces.

FAQ

What materials can this end mill cut?

The cutter is suitable for steel, forge steel, carbon steels, alloy steels, pre‑hardened steels, hardened steels, stainless steel, copper, and copper alloys, as long as the material hardness is below HRC 50.

How does the AlTiN coating benefit the tool?

AlTiN provides a hard, oxidation‑resistant layer that reduces wear and friction, allowing the cutter to operate at higher speeds and temperatures without losing edge integrity.

What is the advantage of a 4‑flute design?

A 4‑flute cutter offers a higher chip load capacity, enabling faster feed rates and smoother finishes compared to 2‑flute designs, especially in tougher materials.

Can this end mill be used on CNC routers?

Yes, the 3/16″ shank and overall length are compatible with standard CNC routers and milling machines, making it a versatile choice for a wide range of machining setups.

What warranty does ACCUCUT provide?

ACCUCUT offers a limited warranty that covers manufacturing defects and ensures replacement or repair of the tool if it fails under normal operating conditions.
