Accupro 12183497 Corner Radius End Mill 5/16 in 4 Flute Carbide

Product Description

The ACCUPRO 12183497 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 5/16 inch diameter, a 1/8 inch (0.1250 inch) corner radius, and a 4-flute spiral geometry that promotes chip evacuation and surface finish quality. The long-length design provides a 1 inch length of cut with a 4 inch overall length, making it well-suited for deeper pocket work and profiling passes. Right-hand cutting and flute direction are standard. This tool is installed and operated by machinists and tooling technicians using CNC mills, vertical machining centers, and manual knee mills.

This end mill is a single-end, centercutting tool, allowing it to plunge directly into material as well as perform peripheral and slot milling. The bright/uncoated finish and micrograin solid carbide construction make it appropriate for use in non-ferrous metals, aluminum, brass, and a range of engineering plastics. The long flute classification gives it additional reach for applications where standard-length tools cannot access the full depth of a feature. It is suited for production shops and job shops requiring consistent corner radius geometry across high-tolerance workpieces.

Key Features

• 5/16 inch mill diameter with a 0.1250 inch corner radius for controlled edge blending
• 4-flute spiral geometry in right-hand cut and right-hand flute direction
• Solid micrograin carbide construction for rigidity and wear resistance
• Centercutting design allows direct plunge entry into workpiece material
• Long-length classification with 1 inch length of cut and 4 inch overall length
• Bright/uncoated finish suitable for non-ferrous and general-purpose machining

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC and manual milling machines accepting a 5/16 inch shank diameter collet or end mill holder.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Secure the shank in a properly sized collet or end mill holder, verifying runout before beginning a cut. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Follow shop-standard feeds, speeds, and depth-of-cut parameters appropriate to the workpiece material and machine rigidity.
