Accupro 14556351 Corner Radius End Mill 1/8 in 4 Flute Carbide

Product Description

The ACCUPRO 14556351 is a solid carbide corner radius end mill designed for precision milling in ferrous and hard materials. With a 1/8 inch cutting diameter and a 0.015 inch corner radius, this tool produces controlled edge breaks and smooth floor-to-wall transitions in tight-tolerance applications. The AlTiN+ coating provides high heat resistance and extended tool life in dry or semi-dry cutting conditions. Featuring 4 flutes in a right-hand spiral configuration, this single-end, centercutting tool is suited for machinists and tool-and-die professionals running CNC milling operations where dimensional accuracy and surface finish are critical.

This end mill is used in CNC vertical and horizontal machining centers for slotting, profiling, and finishing cuts in steel, stainless steel, and other hard alloys. The stub-length geometry keeps deflection low during aggressive cuts. The straight-cylindrical shank mounts directly into standard collets and end mill holders accepting 1/8 inch shanks. It is well suited for die and mold work, fixture machining, and precision part production where corner radius consistency is required.

Key Features

• AlTiN+ coating for high-temperature resistance and extended tool life in hard materials
• 0.015 inch corner radius with a tolerance of plus or minus 0.001 inch for consistent edge geometry
• 4-flute right-hand spiral design for efficient chip evacuation and smooth surface finish
• Centercutting capability allows plunge entry without a pre-drilled hole
• Micrograin solid carbide construction for rigidity and wear resistance
• Stub-length flute geometry reduces deflection in precision finishing applications

Compatibility

Designed as an OEM-style replacement or standard tooling option compatible with CNC milling setups using 1/8 inch straight-cylindrical shank collets or end mill holders. Part of the ACCUPRO Series 6/44 corner radius end mill lineup.

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC tooling setup procedures. Ensure the spindle is fully powered down and the machine is in a safe state before loading or removing tooling. Verify collet size and runout with a dial indicator before committing to a production run. Follow the machine tool manufacturer and cutting tool manufacturer guidelines for speeds, feeds, and depth of cut for the specific workpiece material and coating type.
