Accupro 12182796 Corner Radius End Mill 1/4in 4 Flute Carbide

Product Description

The ACCUPRO 12182796 is a solid carbide corner radius end mill designed for precision milling operations in metal and hard material applications. With a 1/4 inch mill diameter and a 0.02 inch corner radius, this single-end tool produces smooth corner transitions and reduces stress concentrations in milled pockets and profiles. The 4-flute configuration supports efficient chip evacuation while maintaining surface finish quality. A 40-degree helix angle promotes smooth cutting action and reduces chatter. This tool is installed and operated by machinists and tool-and-die professionals on CNC and manual milling equipment.

This end mill suits stub-length applications where rigidity is a priority over reach. The 3/8 inch length of cut and 2 inch overall length make it well-suited for shallow pocket milling, contour profiling, and finish passes in ferrous and non-ferrous materials. The bright/uncoated finish is appropriate for general-purpose use and compatible with a range of cutting fluids and dry cutting setups. The 1/4 inch shank diameter fits standard ER and end mill holders commonly found in production and job-shop environments.

Key Features

• Solid micrograin carbide construction for wear resistance and dimensional stability
• 0.02 inch corner radius reduces corner chipping and stress risers in workpiece geometry
• 4-flute, right-hand spiral design supports both slotting and peripheral milling
• 40-degree helix angle promotes smooth cutting and reduced vibration
• Centercutting capable, allowing plunge entry without a pre-drilled hole
• Bright/uncoated finish suitable for general-purpose milling across a wide range of materials

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for standard 1/4 inch shank end mill holders and collet chucks used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by qualified machinists using appropriate end mill holders or collet chucks rated for the 1/4 inch shank diameter. Ensure the machine spindle is fully stopped and locked out before tool changes. Confirm runout and tool projection before beginning a cut. Follow applicable shop safety standards and manufacturer feed and speed recommendations for the workpiece material.
