Accupro 12185049 Square End Mill 7/16 in 2 Flute Carbide

Product Description

The ACCUPRO 12185049 is a double-end square end mill designed for precision milling operations in metal and composite materials. Built from solid carbide with a micrograin grade substrate, it carries an AlTiN finish that extends tool life in high-heat cutting environments. The cutter measures 7/16 inches in diameter with a 7/8 inch length of cut, mounted on a 1/2 inch shank, and runs an overall length of 4 inches. Two spiral flutes at a 40-degree helix angle promote efficient chip evacuation and reduce cutting forces. This tool is centercutting, allowing plunge entry without a pre-drilled hole.

This end mill is suited for milling operations in job shops, tool rooms, and production machining environments handling ferrous and non-ferrous materials. The AlTiN coating makes it a strong choice for dry or semi-dry cutting of hardened steels and stainless alloys where heat resistance is critical. The double-end configuration provides two usable cutting ends, extending the service interval before replacement. It is sized for use in standard milling machines, machining centers, and CNC routers accepting a 1/2 inch collet or end mill holder.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance
• AlTiN finish for high-temperature and hard-material cutting performance
• Double-end design provides two cutting ends per tool
• 40-degree helix spiral flute for efficient chip evacuation
• Centercutting capable — supports direct plunge milling
• Right-hand cut and right-hand flute configuration

Compatibility

Designed as a standard replacement or production-grade cutting tool for milling machines and CNC machining centers equipped with a 1/2 inch collet, ER chuck, or end mill holder accepting a 1/2 inch shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully in a properly sized collet or end mill holder and verify runout before cutting. Ensure the machine spindle is fully stopped before tool changes. Follow shop safety protocols and applicable OSHA machining guidelines when operating rotating cutting tools.
