Accupro 12183367 Corner Radius End Mill 3/4in 4 Flute Carbide

Product Description

The ACCUPRO 12183367 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. With a 3/4 inch mill diameter, 3 inch length of cut, and a 0.02 inch corner radius, this tool is built for extended reach profiling, slotting, and peripheral milling where edge integrity and dimensional accuracy matter. The micrograin carbide construction supports higher feed rates and longer tool life compared to standard carbide grades. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces in ferrous and non-ferrous materials. This tool is installed and operated by machinists and CNC tooling professionals.

This end mill is suited for production and job-shop machining applications requiring extra long reach into deep pockets, cavities, or stepped features. The single-end, centercutting design allows direct plunge entry as well as conventional ramping operations. The right-hand cutting direction and right-hand spiral flute configuration make it compatible with standard CNC machining centers and manual vertical mills. The bright uncoated finish suits applications where coating reactions or aluminum adhesion are a concern, or where regrinding is anticipated.

Key Features

• 0.02 inch corner radius protects cutting edge and reduces workpiece stress concentration
• Micrograin solid carbide construction for extended tool life and wear resistance
• 40-degree helix angle for efficient chip evacuation in deep-cut applications
• Extra long length classification with 3 inch LOC and 6 inch OAL for deep reach
• Centercutting design allows plunge and ramp entry without pre-drilling
• Bright uncoated finish compatible with a wide range of workpiece materials and regrind programs

Compatibility

Designed as a direct-mount tooling solution for standard 3/4 inch collets, end mill holders, and shrink-fit toolholders used in CNC machining centers and manual vertical mills.

Installation Notes

Installation and setup should be performed by qualified machinists or CNC tooling personnel. Secure the shank fully in a clean, properly sized collet or end mill holder to the recommended engagement depth before operation. Verify spindle runout is within acceptable limits before cutting to avoid premature tool wear or breakage. Always confirm tool path programming accounts for the 0.02 inch corner radius geometry when dimensional tolerances are critical.
