Accupro 14556440 Square End Mill 1/2 in 4-flute Solid Carbide

Product Description

The ACCUPRO 14556440 is a solid carbide square end mill designed for precision milling in ferrous and non-ferrous materials. It features a 0.5-inch mill diameter, a 2-inch length of cut, and a 4-inch overall length with a straight cylindrical shank. The four-flute, spiral-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. An AlTiN+ coating provides enhanced heat resistance and extended tool life in demanding cutting environments. Machined from micrograin carbide, this end mill delivers the rigidity and edge retention required for high-feed milling operations. It is centercutting, allowing plunge entry into the workpiece.

This end mill is suited for use in CNC machining centers and manual mills performing slotting, profiling, and peripheral milling operations. The long-length configuration with a 2-inch length of cut makes it appropriate for applications requiring additional reach, such as deep pocket milling or step milling in medium-to-hard materials. Right-hand cut and right-hand flute geometry match standard spindle rotation on conventional machining equipment. It belongs to the ACCUPRO Series 6/44 lineup, which targets general-purpose and production milling applications.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• AlTiN+ coating for elevated heat resistance and extended tool life
• 40-degree helix angle with spiral flute geometry for efficient chip evacuation
• Centercutting design allows direct plunge entry
• Right-hand cut, right-hand flute for standard spindle compatibility
• Mill diameter tolerance of +0.000 to -0.002 inches for consistent fit and finish

Compatibility

Designed as a direct-fit replacement or production tooling option for CNC and manual milling machines accepting a 0.5-inch straight cylindrical shank. Part of the ACCUPRO Series 6/44.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and the spindle fully stopped. Secure the shank in a compatible collet or end mill holder torqued to the machine tool manufacturer's specification. Inspect the shank and collet for wear or runout before mounting. Follow applicable shop safety procedures and machine guarding requirements during setup and operation.
