Accupro 12183456 Corner Radius End Mill 3/16 in 4 Flute

Product Description

The ACCUPRO 12183456 is a solid carbide corner radius end mill designed for precision milling operations in metal fabrication and machining environments. It features a 3/16 inch cutting diameter with a 0.06 inch corner radius, a 1 inch length of cut, and a 4-inch overall length. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action in a wide range of materials. With four flutes and a bright/uncoated finish, this tool is suited for high-tolerance profiling and finishing passes. It is installed and operated by machinists and tool-and-die professionals working on CNC mills and manual milling machines.

This end mill is appropriate for applications requiring a controlled corner radius in ferrous and non-ferrous materials. Its micrograin carbide grade and long-length configuration make it well suited for reaching into deeper pockets and cavities. The single-end, centercutting design allows plunge entry as well as peripheral and slot milling. Typical use cases include die work, mold work, and precision part profiling where sharp internal corners must be broken to a specific radius specification.

Key Features

• 0.06 inch corner radius with a tolerance of plus or minus 0.00150 inches for precise radius control
• Solid micrograin carbide construction for extended tool life and dimensional stability
• 40-degree helix angle promotes efficient chip flow and reduces cutting forces
• Centercutting design allows direct plunge entry without a pilot hole
• Right-hand flute direction and right-hand cutting orientation for standard CNC mill setup
• Bright/uncoated finish suitable for use with cutting fluids in a variety of workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC and manual milling machines accepting a 3/16 inch shank diameter collet or end mill holder.

Installation Notes

Installation is performed by a qualified machinist. Ensure the milling machine spindle is fully powered down and the tool holder is clean and free of debris before seating the shank. Use a properly sized collet or end mill holder rated for a 3/16 inch shank diameter and torque the drawbar or clamping nut according to the tool holder manufacturer specifications. Verify runout with a dial indicator before commencing cuts to protect both the tool and the workpiece.
