Accupro 312182 Square End Mill 1/2 in 5 Flute Solid Carbide

Product Description

The ACCUPRO 312182 is a solid carbide square end mill designed for high-performance milling operations in ferrous and non-ferrous metals. It features a 1/2 inch diameter with a 5/8 inch length of cut and runs five flutes with a 38-degree helix angle for aggressive chip evacuation and smooth surface finishes. The AlTiCrN coating provides heat resistance and extended tool life in demanding cutting conditions. A variable index geometry reduces harmonic vibration during cuts. Machinists and tool-and-die professionals install this end mill in CNC machining centers and manual mills requiring a rigid, single-end cutting tool in a 1/2 inch shank configuration.

This end mill is suited for applications where high material removal rates and fine finishes are required in a single-end configuration. The extended reach of 1.5 inches allows access to deeper pockets and stepped features without tool changes. The right-hand flute direction and right-hand cutting orientation are standard for conventional CNC spindle setups. It is part of the ACCUPRO HS series, which targets production machining environments where tool consistency and coating durability are priorities. The centercutting capability allows direct plunge entry without pre-drilling.

Key Features

• Solid carbide micrograin substrate for rigidity and wear resistance
• AlTiCrN coating for high-heat and abrasion resistance in ferrous materials
• 5 flutes with 38-degree helix angle for efficient chip evacuation
• Variable index flute spacing reduces chatter and vibration
• Centercutting design allows direct plunge milling
• Extended reach of 1.5 inches for deep pocket and stepped feature access

Compatibility

Designed as an OEM-style replacement for solid carbide square end mills in the 1/2 inch shank class, compatible with standard ER collet chucks, shrink-fit holders, and side-lock holders accepting 1/2 inch shank tooling.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols and machine tool manufacturer guidelines. Secure the shank to the minimum recommended insertion depth in a clean, burr-free collet or tool holder before tightening. Verify spindle RPM and feed rate against the material being cut before engaging the workpiece. Never exceed the rated depth of cut for the flute length.
