Accupro 14788572 Square End Mill 3/8 Inch 4 Flute Solid Carbide

Product Description

The ACCUPRO 14788572 is a solid carbide square end mill designed for precision milling operations in metal fabrication, tool and die, and general machining applications. With 4 helical flutes and a centercutting geometry, this end mill can plunge directly into workpiece material, making it suitable for slot milling, profiling, and pocketing. The mill diameter is 0.375 inches (3/8 inch) with a matching 0.375-inch cylindrical shank. The length of cut is 1.0 inch and the overall length is 4.0 inches. Solid carbide construction delivers hardness and wear resistance well beyond high-speed steel alternatives, making it appropriate for production environments and harder workpiece materials.

This end mill is suited for use in CNC machining centers, manual knee mills, and toolroom setups handling ferrous and non-ferrous materials. The helical flute design improves chip evacuation and reduces cutting forces during peripheral and slot milling passes. The centercutting capability eliminates the need for a pre-drilled pilot hole when entering solid material. It is installed and operated by machinists, tool and die makers, and CNC operators working in job shops, manufacturing facilities, and maintenance machine shops.

Key Features

• Solid carbide construction for high hardness and extended tool life
• 4 helical flutes for efficient chip evacuation and smooth surface finish
• Centercutting geometry allows direct plunge entry into solid material
• 3/8 inch mill diameter with 1.0 inch length of cut
• Cylindrical shank for standard collet and end mill holder compatibility
• 4.0 inch overall length suits standard toolholding setups

Compatibility

Designed as a direct-fit replacement end mill for standard 3/8 inch collets, end mill holders, and shrink-fit toolholders used in CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down and lock out the machine spindle before inserting or removing the end mill from the toolholder. Ensure the shank is fully seated and the collet or set screw is torqued according to the toolholder manufacturer specifications. Inspect the cutting edges for chips or damage before each use and replace the tool if wear is visible.
