Accupro 14788589 Corner Radius End Mill 1/2 in 4 Flute Carbide

Product Description

The ACCUPRO 14788589 is a solid carbide corner radius end mill designed for precision milling in demanding metalworking applications. Built with 4 spiral flutes and a 0.1300-inch corner radius, it produces smooth, radiused transitions on workpiece edges while maintaining tight dimensional tolerances. The AlTiN+ coating provides high heat resistance and extended tool life in ferrous and hardened materials. With a 1/2-inch cutting diameter and 1-1/2-inch length of cut, this single-end, centercutting tool handles slotting, profiling, and plunging operations. It is installed and run by machinists and CNC operators in job shops and production environments.

This end mill is suited for CNC machining centers and manual milling machines operating on steel, stainless steel, cast iron, and similar hard materials. The centercutting geometry allows direct plunge entry, making it versatile for pocket milling, contouring, and finishing passes where a controlled corner radius is required. The 1-inch shank diameter and 6-inch overall length accommodate setups that require extended reach without sacrificing rigidity.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN+ coating enhances heat resistance and extends tool life in ferrous applications
• 0.1300-inch corner radius reduces stress concentrations and improves surface finish at part edges
• Centercutting design allows direct plunge entry for pocket and slot operations
• 4 spiral flutes provide efficient chip evacuation and smooth cutting action
• Right-hand cutting direction compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC machining centers and manual mills accepting a 1-inch straight shank tool holder.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Secure the shank fully in a collet chuck or end mill holder to the recommended engagement depth before tightening. Verify spindle speed and feed rate are appropriate for the workpiece material and tool diameter before running. Inspect the cutting edges for chips or wear before each use and do not exceed the rated length of cut.
