Accupro 12183371 Corner Radius End Mill 3/4 in 4 Flute

Product Description

The ACCUPRO 12183371 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. With a 3/4 inch diameter and a 0.09 inch corner radius, it produces clean, radiused cuts that reduce stress concentrations at part corners. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Running 4 right-hand spiral flutes in a right-hand cutting direction, this extra-long series end mill offers a 3 inch length of cut and a 6 inch overall length, making it suitable for deep-pocket and extended-reach applications. Machinists and CNC operators are the primary users of this tool.

This end mill is suited for use in CNC machining centers and manual mills working with ferrous and non-ferrous materials where a corner radius profile is required. The single-end, centercutting design allows plunge entry as well as lateral passes. The extra-long configuration accommodates workpieces or fixtures requiring clearance beyond what standard-length end mills can reach. The bright, uncoated finish makes it appropriate for applications where coating interaction with the workpiece material is a concern or where re-sharpening is planned.

Key Features

• 0.09 inch corner radius for stress-reducing radiused edges on machined parts
• Micrograin solid carbide construction for rigidity and wear resistance
• 40-degree helix angle promotes efficient chip evacuation during deep cuts
• Extra-long series with 3 inch LOC and 6 inch OAL for deep-pocket access
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Bright, uncoated finish compatible with a wide range of materials and re-sharpening workflows

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool for CNC machining centers and manual mills accepting a 3/4 inch straight shank end mill.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. The machine spindle must be fully stopped and the tool changer or spindle lock engaged before inserting or removing the end mill from the collet or tool holder. Verify that shank diameter tolerance and runout are within acceptable limits before operation, as improper seating can cause tool deflection or breakage. Follow applicable shop safety procedures and machine manufacturer guidelines for tool clamping torque and maximum RPM ratings for this diameter and reach.
