Accupro 12182395 Square End Mill 0.138 in 4 Flute Carbide

Product Description

The ACCUPRO 12182395 is a solid carbide square end mill designed for precision milling operations in metal fabrication and machining applications. With a 0.138-inch (3.50 mm) cutting diameter and a 0.4724-inch length of cut, this tool delivers accurate material removal in ferrous and non-ferrous metals. The micrograin carbide construction provides superior hardness and edge retention compared to standard carbide grades. A TiCN (Titanium Carbonitride) coating reduces friction and increases surface hardness, extending tool life in abrasive cutting conditions. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action, making this end mill well suited for finishing and semi-finishing passes.

This end mill is intended for use in CNC machining centers and manual milling machines where tight tolerances and fine surface finishes are required. The regular length configuration suits typical pocket milling, slotting, and profiling operations in tool and die shops, production machining environments, and maintenance repair settings. The centercutting geometry allows plunge entry directly into the workpiece, adding versatility to the tool path options available to the operator. Right-hand cut and right-hand flute direction conform to standard spindle configurations found on most vertical machining centers.

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills accepting a 4.00 mm (0.1575-inch) shank diameter end mill holder or collet chuck.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before tool changes. Use a properly sized collet or end mill holder matching the shank diameter and torque the retention system per the machine tool manufacturer specifications. Verify runout with a dial indicator after installation before beginning a cut.
