Accupro 12181687 Square End Mill 15/32 in 2 Flute Solid Carbide

Product Description

The ACCUPRO 12181687 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 15/32 inch (0.4688 inch) mill diameter, a 5/8 inch length of cut, and a 1/2 inch shank diameter with an overall length of 2-1/2 inches. The micrograin carbide substrate and TiCN coating deliver hardness and lubricity for improved tool life in demanding cutting environments. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces. This is a stub-length, centercutting tool, making it suitable for both plunge and peripheral milling operations.

This end mill is used in CNC machining centers, knee mills, and manual milling setups where tight tolerances and surface finish matter. The stub-length geometry increases rigidity and reduces deflection, making it well suited for shallow-to-moderate depth-of-cut applications in tool rooms, job shops, and production environments. It is installed and operated by machinists and CNC operators working with steel, stainless, cast iron, and similar materials where TiCN coating provides a wear advantage.

Key Features

• Solid micrograin carbide construction for high rigidity and wear resistance
• TiCN finish provides surface hardness and low friction for extended tool life
• 40-degree right-hand spiral flute promotes efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece material
• Stub-length (2-1/2 inch OAL) geometry minimizes deflection in tight setups
• Mill diameter tolerance of +0.000 / -0.002 inches for consistent fit and finish

Compatibility

Designed as a standard shank replacement end mill for use in any milling spindle or collet chuck accepting a 1/2 inch straight shank. No specific compatible machine models were provided in the product data.

Installation Notes

This tool is installed by qualified machinists or CNC operators. Ensure the spindle and collet are clean and free of chips before seating the shank to achieve proper runout. Follow the machine tool manufacturer guidelines for collet torque and tool stick-out. Always verify spindle speed and feed rate parameters against the coating and substrate recommendations before running the first cut.
