Accupro 14799520 Corner Radius End Mill 1/4 Inch 2 Flute Carbide

Product Description

The ACCUPRO 14799520 is a solid carbide corner radius end mill designed for precision milling operations requiring a controlled edge radius and tight dimensional tolerances. Built from micrograin solid carbide with a bright/uncoated finish, this tool delivers consistent performance in ferrous and non-ferrous materials. It features a 0.25 inch mill diameter, a 0.0100 inch corner radius, and a 2-flute right-hand spiral configuration with a 30-degree helix angle. The single-end, centercutting design allows plunge entry and side milling in a single setup. Machinists and tool-and-die professionals working with miniature components and fine-detail milling will find this tool well suited to close-tolerance work.

This end mill is engineered for miniature-series milling applications where small diameters and precise corner geometry are required. It is used in CNC machining centers and manual mills for slotting, profiling, and contouring in tight-clearance workpieces. The 0.75 inch length of cut and 2.5 inch overall length make it appropriate for shallow-to-medium depth passes in small-part production, mold work, and precision component fabrication. The right-hand cutting direction is compatible with standard spindle rotation on conventional machining equipment.

Key Features

• 0.0100 inch corner radius for controlled edge break and reduced stress concentration at milled corners
• Micrograin solid carbide construction for hardness and wear resistance
• 2-flute right-hand spiral design with 30-degree helix for efficient chip evacuation
• Centercutting geometry allows direct plunge entry without pre-drilling
• Bright/uncoated finish suitable for a broad range of workpiece materials
• Single-end configuration optimized for miniature-series precision milling

Compatibility

Designed as an OEM-style replacement and standard tooling option for miniature-series corner radius milling applications on CNC machining centers and manual mills accepting a 0.25 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist familiar with end mill toolholding practices. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Verify collet or toolholder bore matches the 0.25 inch shank diameter and that runout is within acceptable limits before beginning a cut. Follow shop safety procedures and machine manufacturer guidelines for speeds, feeds, and depth of cut.
