Accupro 14797579 Corner Radius End Mill 1/8 in 4 Flute

Product Description

The ACCUPRO 14797579 is a solid carbide corner radius end mill designed for precision milling in demanding metalworking applications. It features a 1/8 inch diameter with a 0.0300 inch corner radius and four right-hand spiral flutes, delivering smooth cutting action and improved surface finish on hardened and abrasive materials. The AlTiN coating provides high heat resistance and extended tool life at elevated cutting speeds. With a 1/2 inch length of cut and 1-1/2 inch overall length, this miniature single-end tool is suited for tight-tolerance work in die, mold, and aerospace component machining. Machinists and tool-and-die professionals are the primary users.

This end mill fits applications where small-diameter, high-accuracy profiling and slotting are required. The miniature series designation makes it appropriate for fine detail work in mold cavities, micro-features, and intricate contour milling on ferrous and non-ferrous metals. The centercutting geometry allows direct plunge entry, adding flexibility in programming and setup. The 30-degree helix angle supports chip evacuation in shallow-to-moderate depth-of-cut passes. This tool is used in CNC machining centers and high-speed spindle setups.

Key Features

• 0.0300 inch corner radius reduces stress concentration and improves edge durability on workpiece corners
• AlTiN coating enhances heat resistance and wear life in dry or high-speed cutting conditions
• 4-flute right-hand spiral design provides good surface finish and rigidity in profiling cuts
• Centercutting geometry allows plunge milling without a pre-drilled entry hole
• Micrograin solid carbide substrate offers consistent edge integrity at small diameters
• Miniature series with 1/8 inch shank matches common small-bore collets and tool holders

Compatibility

Designed as an OEM-style replacement or direct-use miniature end mill for CNC machining center setups requiring a 1/8 inch shank, 4-flute corner radius geometry, and AlTiN coating.

Installation Notes

Installation is performed by qualified machinists following standard CNC tooling procedures. Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before changing tooling. Seat the 1/8 inch shank fully in a matching collet or end mill holder and torque to the tool holder specification. Verify runout with a dial indicator before initiating the first cut to protect the small-diameter cutting edge.
