Accupro 12183146 Corner Radius End Mill 3/4 in 4 Flute Ticn

Product Description

The ACCUPRO 12183146 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 0.75 inch mill diameter, a 2.25 inch length of cut, and a 0.03 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding applications. The TiCN coating provides high surface hardness and reduced friction, making this tool well-suited for cutting ferrous and non-ferrous alloys. It is a single-end, centercutting design with right-hand flute direction and right-hand cutting action. Machinists and toolroom professionals are the primary users of this tool in CNC vertical and horizontal milling applications.

This end mill is built for long-reach roughing and finishing passes where a standard-length tool cannot reach. The 5 inch overall length and 0.75 inch shank diameter support rigid setups in deep-cavity milling, die and mold work, and profile machining. The micrograin carbide substrate maintains edge integrity at elevated spindle speeds and feeds. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action across a range of workpiece materials.

Key Features

• 0.03 inch corner radius reduces edge chipping and stress on workpiece corners
• TiCN coating for increased surface hardness and wear resistance
• Micrograin solid carbide substrate for consistent edge retention
• 40-degree helix angle promotes efficient chip evacuation
• Centercutting design allows plunge entry into the workpiece
• Single-end, right-hand cutting with long-length classification for deep-reach applications

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC milling machines and machining centers accepting a 0.75 inch round shank. No specific OEM model compatibility was stated in the product data.

Installation Notes

Installation requires a compatible collet, end mill holder, or shrink-fit toolholder sized for a 0.75 inch shank. Ensure the machine spindle is fully powered down and locked before changing tooling. Verify runout at the tool tip after seating to maintain dimensional accuracy. Follow the tool manufacturer and machine manufacturer guidelines for speed and feed selection based on workpiece material.
