YG-1 56584TF Corner Radius End Mill 3/8 in 3 Flute

Product Description

The YG-1 56584TF is a single-end corner radius end mill machined from solid carbide and coated with TiAlN-Futura for extended tool life in ferrous materials. It features a 3/8-inch cutting diameter, a 1-inch length of cut, and a corner radius range of 0.0150 to 0.0200 inches. The three-flute, right-hand helical geometry with a coarse pitch is engineered for roughing operations, delivering aggressive material removal while managing heat and chip evacuation. This tool is intended for use by machinists and toolroom professionals running CNC milling equipment.

The 56584TF is suited for roughing and general-purpose milling in steel, stainless steel, and cast iron. Its 35-degree medium helix angle balances cutting forces across demanding workpiece materials. The straight cylindrical shank measures 3/8 inch in diameter, making it compatible with standard end mill holders on vertical and horizontal machining centers. This is a standard-length tool appropriate for most production and job-shop milling setups where reach extension is not required.

Key Features

• TiAlN-Futura CVD coating provides thermal resistance and extended tool life in steel and stainless steel
• Solid carbide construction delivers rigidity and wear resistance beyond high-speed steel tooling
• Corner radius geometry reduces stress concentration at the cutting edge and improves surface finish at part corners
• Three-flute coarse-pitch design optimized for roughing and aggressive material removal
• Center-cutting capability allows plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle rotation

Compatibility

Designed for use with standard end mill holders accepting a 3/8-inch straight cylindrical shank. Primary workpiece materials are steel and stainless steel; secondary application includes cast iron. Material grades and application codes P, M, and K are supported per the supplier specification.

Installation Notes

This tool is installed by a machinist or toolroom technician into an end mill holder on a CNC or manual milling machine. The machine spindle must be stopped and locked before tool changes. Confirm runout at the shank with a dial indicator before initiating cuts, as excessive runout accelerates edge wear on carbide tooling. Do not exceed the rated depth of cut or feed rate for the workpiece material without verifying tool and machine capability.
