Accupro 14505812 3/8 Inch 4 Flute Solid Carbide Square End Mill

Product Description

The ACCUPRO 14505812 is a solid carbide square end mill designed for precision milling in metalworking and machining operations. It features a 3/8-inch cutting diameter, a 5/8-inch length of cut, and a stub-length 2-inch overall length that keeps the tool rigid and reduces deflection at higher feed rates. The AlTiN+ coating provides elevated heat and wear resistance, making this end mill well-suited for harder ferrous materials. With four spiral flutes and a 40-degree helix angle, it promotes efficient chip evacuation and smooth cutting action. A licensed machinist or CNC operator is the typical end user.

This end mill is built for right-hand cutting with right-hand flute direction and is centercutting, allowing it to plunge directly into workpieces. It is a strong candidate for slotting, profiling, and finish milling in both manual and CNC machining centers. The micrograin carbide substrate and straight-cylindrical shank ensure consistent tool runout and secure collet retention in standard ER or similar toolholding systems. Typical applications include ferrous and hard alloy milling in job shops, production machining, and toolroom environments.

Key Features

• Solid micrograin carbide construction for high rigidity and extended tool life
• AlTiN+ coating for superior heat resistance and wear performance in harder materials
• 4-flute spiral design with 40-degree helix for efficient chip evacuation
• Centercutting geometry allows direct plunge entry into the workpiece
• Right-hand cut and right-hand flute direction for standard spindle compatibility
• Stub length (2-inch OAL) reduces deflection and improves rigidity during aggressive cuts

Compatibility

Designed as a Series 6/44 stub-length square end mill compatible with standard straight-cylindrical toolholders and collet systems accepting a 3/8-inch shank diameter.

Installation Notes

Installation and tool changes should be performed only with the machine spindle fully stopped and the control in an e-stop or tool-change mode. Ensure the collet and toolholder bore are clean and free of chips before seating the shank. Verify runout with a dial indicator after clamping to confirm proper seating. Always follow the machine manufacturer and tooling guidelines for speed and feed parameters when commissioning a new tool.
