Accupro 14556357 Corner Radius End Mill 1/8 in 4 Flute

Product Description

The ACCUPRO 14556357 is a solid carbide corner radius end mill designed for high-performance milling in ferrous and non-ferrous metals. It carries a 1/8 inch cutting diameter with a 0.015 inch corner radius and a 1/2 inch length of cut, making it suited for fine detail work, slotting, and profiling where edge breakout and workpiece finish are critical. The AlTiN+ coating extends tool life in dry and semi-dry cutting conditions by improving heat resistance and reducing edge buildup. This tool is a single-end, center-cutting design with four flutes in a right-hand spiral configuration, turning right-hand direction. It is installed and used by machinists and CNC tool-and-die technicians.

This end mill is well suited for close-tolerance profiling, pocket milling, and finishing passes on hardened steels, stainless alloys, and cast iron. The 1/8 inch shank fits standard collet toolholders found on vertical machining centers and CNC mills. Its regular-length geometry and 40-degree helix angle promote chip evacuation and reduce chatter in shallow-to-mid depth cuts. The micrograin carbide substrate maintains edge integrity at elevated spindle speeds typical of high-speed machining operations.

Key Features

• 1/8 inch cutting diameter with 0.015 inch corner radius for controlled edge geometry
• AlTiN+ coating for extended tool life in high-heat cutting environments
• Four-flute right-hand spiral design promotes efficient chip evacuation
• Center-cutting capability allows plunge entry into workpiece material
• Micrograin solid carbide substrate for rigidity and edge retention
• 1/8 inch straight cylindrical shank fits standard collet holders

Compatibility

Designed as an OEM-style replacement for solid carbide corner radius end mills in the 1/8 inch diameter class; fits standard 1/8 inch collet toolholders on vertical machining centers and CNC milling equipment.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Always power down and lock out the spindle before changing tooling. Seat the shank fully in the collet and torque the collet nut according to the toolholder manufacturer specification. Inspect the corner radius and cutting edges under magnification before use to confirm no chips or coating damage occurred during handling.
