Accupro 14556352 Corner Radius End Mill 1/8 in 4 Flute

Product Description

The ACCUPRO 14556352 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. With a 1/8 inch cutting diameter and a 0.02 inch corner radius, this tool produces a controlled edge break that reduces chipping and extends part life in hardened and abrasive materials. The AlTiN+ coating provides high heat resistance and lubricity, making it well suited for dry or semi-dry cutting in ferrous metals, stainless steel, and high-temperature alloys. Machinists and CNC operators install this tool in standard 1/8 inch toolholders for finish and semi-finish passes where edge integrity is critical.

This end mill is used in precision CNC milling operations across job shops, tool-and-die, aerospace component machining, and medical part production. The stub length type and 1/4 inch length of cut make it appropriate for shallow-to-moderate pocket milling and profiling where rigidity is a priority. The single-end, centercutting design allows both plunge and peripheral cutting. Right-hand flute direction and right-hand cutting direction are standard for conventional CNC spindle rotation.

Key Features

• AlTiN+ coating for high heat resistance in ferrous and high-temperature alloy cutting
• 0.02 inch corner radius reduces edge chipping and improves surface finish
• 4 flutes with right-hand spiral for efficient chip evacuation and surface quality
• Centercutting geometry enables direct plunge entry without pre-drilling
• Micrograin solid carbide substrate for wear resistance and dimensional stability
• Straight-cylindrical shank fits standard 1/8 inch collets and toolholders

Compatibility

Designed as an OEM-style replacement or direct-use tool for CNC machining centers and manual mills equipped with 1/8 inch straight-bore collets or toolholders accepting a straight-cylindrical shank.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Always power down and lock out the spindle before inserting or removing tooling. Seat the shank fully into the collet or toolholder to the minimum grip depth before torquing the retention nut. Verify runout with a dial indicator after seating, as excessive runout on a 1/8 inch diameter tool accelerates premature wear and breakage.
