Accupro 12182444 Square End Mill 7/32 in 4 Flute Carbide

Product Description

The ACCUPRO 12182444 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 7/32 inch (0.2188 inch) mill diameter, a 5/8 inch length of cut, and a 1/4 inch shank diameter, with an overall length of 2-1/2 inches. The AlTiN coating provides thermal resistance and extended tool life in high-speed applications. The 40-degree helix angle promotes efficient chip evacuation, and the spiral flute geometry delivers consistent surface finishes. This tool is installed by machinists and toolroom professionals on CNC machining centers and manual mills.

This end mill is suited for general-purpose profiling, slotting, and peripheral milling in shop and production environments. The centercutting design allows for plunge entry, expanding its range of applications without requiring a pre-drilled pilot hole. With four flutes and a right-hand cut and right-hand flute configuration, it is well-matched for finishing and semi-finishing passes on both conventional and CNC setups. The micrograin carbide substrate provides rigidity and wear resistance at elevated cutting speeds.

Key Features

• Solid micrograin carbide construction for wear resistance and rigidity
• AlTiN finish for thermal protection in high-speed and dry cutting applications
• 40-degree helix angle for improved chip flow and reduced cutting forces
• Centercutting design allows direct plunge entry into workpiece material
• Four-flute spiral configuration suited for finishing and semi-finishing passes
• Right-hand cut and right-hand flute direction for standard spindle compatibility

Compatibility

Designed as a standard shank end mill for use in collet chucks, end mill holders, and shrink-fit tooling systems that accept a 1/4 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists. Ensure the spindle is fully stopped and the machine is in a safe state before loading or unloading the tool. Seat the shank fully into the holder and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning cuts to protect both the tool and the workpiece.
