Accupro 14556358 Corner Radius End Mill 1/8 in 4 Flute

Product Description

The ACCUPRO 14556358 is a solid carbide corner radius end mill designed for precision milling in demanding metalworking applications. With a 1/8 inch cutting diameter and a 0.03 inch corner radius, it generates a controlled radius on workpiece edges and pockets while reducing stress concentrations at corners. The AlTiN+ coating extends tool life in high-temperature cutting environments, making it well suited for hardened steels, stainless, and heat-resistant alloys. Four flutes and a 40-degree helix angle optimize chip evacuation and surface finish. This tool is installed and operated by machinists and CNC programmers in job shops, production facilities, and toolrooms.

This end mill fits standard 1/8 inch collets and is used in vertical machining centers, CNC mills, and manual mills for slotting, profiling, and finishing passes where a radiused corner is required. The centercutting geometry allows plunge entry into the workpiece. It is a single-end tool from the Series 6/44 line, intended for regular-length reach applications. Typical materials include ferrous metals, tool steels, and similar hard or abrasive workpiece materials where AlTiN+ coating performance is advantageous.

Key Features

• Solid carbide micrograin substrate for rigidity and wear resistance in hard materials
• AlTiN+ coating provides thermal protection and extended tool life in high-heat cuts
• 0.03 inch corner radius reduces edge chipping and workpiece stress risers
• Four right-hand spiral flutes with 40-degree helix for efficient chip evacuation
• Centercutting design allows direct plunge entry without a pre-drilled hole
• Straight cylindrical shank fits standard 1/8 inch ER collets and end mill holders

Compatibility

Designed for use in CNC machining centers and manual mills equipped with a 1/8 inch collet or end mill holder accepting a straight cylindrical shank.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into a clean, undamaged collet or holder and torque the retention nut to the tool holder manufacturer specification. Verify runout with a dial indicator before initiating a cutting program, as excessive runout on a small-diameter end mill accelerates tool wear and can cause breakage.
