Accupro 14788470 Corner Radius End Mill 3/16in 4 Flute

Product Description

The ACCUPRO 14788470 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hardened materials. It features a 3/16 inch (0.1880 inch) diameter with a 0.0600 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding cuts. The 4-flute spiral geometry and AlTiN+ coating provide thermal resistance and hardness at elevated cutting temperatures. With a 5/8 inch length of cut and 2 inch overall length, this single-end, centercutting tool is suited for slotting, profiling, and ramping in CNC machining centers operated by machinists and toolroom professionals.

This end mill is intended for use in CNC vertical and horizontal machining centers where corner radii are required on finished part geometry. The centercutting design allows plunge entry, making it suitable for pocket milling and interpolation operations. The right-hand cutting direction and AlTiN+ coating make it effective in dry or minimum-quantity lubrication cutting of alloy steels, stainless steels, and cast iron. It is a single-end tool, so the full tool is consumed before replacement.

Key Features

• 0.0600 inch corner radius reduces edge chipping and improves surface finish on milled corners
• AlTiN+ coating provides high-temperature hardness and oxidation resistance for dry or high-speed cutting
• 4-flute spiral geometry balances chip evacuation with rigidity for ferrous materials
• Centercutting design enables plunge milling and ramp entry without a pre-drilled pilot hole
• Solid carbide construction delivers greater rigidity and wear resistance compared to HSS tooling
• Right-hand cutting direction compatible with standard CNC spindle orientation

Compatibility

Designed as an OEM-style solid carbide corner radius end mill suitable for standard CNC toolholders accepting a 3/16 inch shank diameter.

Installation Notes

Installation is performed by machinists using a collet chuck or end mill holder rated for the shank diameter. Ensure the toolholder bore and collet are clean and free of chips before seating the tool. Confirm spindle speed and feed rate are set per the material being cut before initiating the program. Do not exceed the rated length of cut to avoid deflection or tool breakage.
