Accupro 12182901 Square End Mill 0.3937 in 4 Flute Carbide

Product Description

The ACCUPRO 12182901 is a solid carbide square end mill designed for precision milling operations in metal cutting and machining applications. Built from micrograin carbide and finished with a titanium carbonitride (TiCN) coating, this tool delivers extended wear resistance and thermal stability at the cutting edge. It features a 4-flute spiral configuration with a 40-degree helix angle for efficient chip evacuation and smooth surface finishes. At 0.3937 inches in diameter with a 0.5512-inch length of cut, this stub-length end mill is well suited for high-rigidity setups where deflection control is critical. Licensed machinists and toolroom technicians are the primary users.

This end mill fits standard milling operations on CNC machining centers, knee mills, and manual milling machines. The stub length type and 2-3/4-inch overall length make it appropriate for applications requiring close-tolerance side milling, slotting, and profiling in ferrous and non-ferrous materials. The TiCN coating performs well on hardened steels, cast iron, and stainless alloys where tool life and finish quality are priorities. Right-hand cut and right-hand flute orientation are standard for conventional and climb milling setups.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiCN finish for improved hardness and thermal resistance at the cutting edge
• 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces
• Centercutting design allows plunge entry into the workpiece
• Stub length reduces overhang and maximizes rigidity in tight setups
• Right-hand cut, right-hand flute for standard milling machine spindle compatibility

Compatibility

Designed as a general-purpose replacement or toolroom-stock solid carbide square end mill for CNC and manual milling applications requiring a 0.3937-inch diameter, 10 mm shank, stub-length tool with TiCN coating.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Secure the shank fully into a collet or end mill holder to the recommended engagement depth before tightening. Verify spindle speed and feed rate settings match the workpiece material and coating specifications before initiating a cut. Inspect the cutting edges and coating for wear or chipping during scheduled tool changes.
