Accupro 12182488 Corner Radius End Mill 5/16 in 4 Flute

Product Description

The ACCUPRO 12182488 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It measures 5/16 inches in diameter with a 3/4 inch length of cut and a 0.01 inch corner radius, making it suited for producing controlled edge breaks and contoured profiles in a single pass. The micrograin carbide construction provides rigidity and wear resistance at elevated cutting speeds. This tool is installed and operated by machinists and tool-and-die professionals on CNC machining centers and manual mills. The single-end, centercutting design allows plunge and ramp entry without secondary tooling.

This end mill is appropriate for ferrous and non-ferrous machining applications where a small, consistent corner radius is required on finished workpiece edges. The bright, uncoated finish makes it suitable for use with cutting fluids in general-purpose milling of steel, cast iron, and aluminum. With a 2-1/2 inch overall length and 5/16 inch shank diameter, it fits standard collet and end mill holder setups without adaptation. The right-hand flute direction and right-hand cutting orientation are the standard configuration for conventional CNC spindle rotation.

Key Features

• 0.01 inch corner radius for controlled edge profiling and reduced stress concentrations
• Micrograin solid carbide construction for rigidity and extended tool life
• 4-flute spiral geometry with centercutting capability for plunge and ramp entry
• Bright, uncoated finish compatible with a wide range of cutting fluids and materials
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• 40-degree helix angle promotes chip evacuation during higher-feed passes

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills accepting a 5/16 inch shank end mill holder or collet.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's setup procedures. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the collet or end mill holder and torque the retention system to the tool holder manufacturer's specification. Verify runout with a dial indicator before commencing a cutting pass.
