Accupro 12176889 Corner Radius End Mill 0.0469 in 4 Flute

Product Description

The ACCUPRO 12176889 is a solid carbide corner radius end mill designed for precision milling in demanding machining environments. It measures 0.0469 inches in diameter with a 0.005-inch corner radius and delivers a 0.625-inch length of cut. The four-flute, right-hand spiral geometry provides efficient chip evacuation and smooth surface finishes on ferrous and non-ferrous materials. An AlTiN coating improves heat resistance and extends tool life in high-speed cutting applications. This single-end, centercutting tool is suited for machinists and CNC operators working in job shops, aerospace, and precision manufacturing.

This end mill is used in vertical and horizontal milling operations where a corner radius profile is required to reduce stress concentrations and improve part durability. The 0.0469-inch diameter makes it well suited for fine detail work, tight pockets, and small-feature milling in hardened steels and high-temp alloys. The 1/8-inch shank diameter fits standard collet toolholders on CNC machining centers and manual mills. It is a single-end tool, so once the cutting end is worn, the tool is replaced rather than flipped.

Key Features

• 0.0469-inch mill diameter with 0.005-inch corner radius for controlled edge geometry
• AlTiN coating for elevated heat resistance and extended tool life in hard materials
• 4-flute right-hand spiral design for efficient chip removal and surface finish quality
• Centercutting geometry allows plunge milling capability
• Micrograin solid carbide construction for rigidity and wear resistance
• 1.5-inch overall length with 1/8-inch shank for compatibility with standard collet systems

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills using 1/8-inch collet toolholders requiring a corner radius end mill profile.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool changer or collet is properly released before inserting or removing the tool. Verify collet runout and toolholder cleanliness before seating the shank to maintain dimensional accuracy. Follow machine manufacturer guidelines and applicable shop safety procedures when setting tool length offsets and cutting parameters.
