Accupro 14797537 Corner Radius End Mill 0.09in 2 Flute Altin

Product Description

The ACCUPRO 14797537 is a solid carbide corner radius end mill designed for precision milling of hardened and abrasion-resistant materials. It features a 0.09 inch cutting diameter with a 0.015 inch corner radius and a 0.4375 inch length of cut. The AlTiN coating provides thermal resistance and extended tool life at elevated cutting speeds. With two right-hand spiral flutes and a 30-degree helix angle, this end mill delivers efficient chip evacuation and smooth surface finishes. Machining professionals and tool-and-die shops use this style of end mill for finishing and semi-finishing passes where edge integrity and dimensional control are critical.

This end mill is sized for miniature-series applications where tight geometries and small part features demand reduced-diameter tooling. The 1/8 inch shank diameter makes it compatible with standard collet and tool-holder systems used on CNC machining centers, CNC mills, and high-speed spindles. It is suited for mold cavities, fine detail work, and contour milling in materials such as hardened steel, stainless, and cast iron where the AlTiN coating provides oxidation resistance. Single-end, centercutting geometry allows plunge entry as well as peripheral and slot milling operations.

Key Features

• 0.015 inch corner radius reduces stress concentration and extends part and tool life at milled edges
• AlTiN coating delivers high heat resistance and wear resistance for hard-material applications
• Micrograin solid carbide substrate provides rigidity and edge retention in miniature-diameter form factor
• Centercutting design permits plunge milling and ramp entry without a pre-drilled hole
• Right-hand cut, right-hand spiral with 30-degree helix for efficient chip removal and reduced chatter
• Single-end construction with 1/8 inch shank fits standard miniature collet systems

Compatibility

Designed as an OEM-style replacement or direct-use miniature corner radius end mill for CNC machining centers and manual mills equipped with 1/8 inch collet or tool-holder systems.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, locked-out state. Ensure the collet and tool holder are clean and free of chips before seating the shank to maintain runout tolerance. Verify that programmed feeds, speeds, and depth-of-cut values are appropriate for the workpiece material and this tool diameter before starting a cut. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when handling carbide tooling.
