Accupro 14556362 Corner Radius End Mill 3/16in 4 Flute

Product Description

The ACCUPRO 14556362 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hardened materials. It features a 3/16 inch cutting diameter with a 0.02 inch corner radius that reduces stress concentration at the cutting edge and extends tool life compared to sharp-corner geometries. The 4-flute, right-hand spiral configuration delivers efficient chip evacuation and a quality surface finish. An AlTiN+ coating provides high-temperature oxidation resistance, making this tool well suited for dry or high-speed cutting applications. Licensed machinists and CNC operators are the primary users of this tool in shop and production environments.

This end mill is used in CNC machining centers and manual mills for slotting, profiling, and peripheral milling of steel, stainless steel, cast iron, and other hard materials. The stub-length design with a 3/8 inch length of cut and 2 inch overall length provides rigidity in applications where deflection must be minimized. The centercutting geometry allows plunge entry. The straight cylindrical shank diameter of 3/16 inch fits standard ER collet chucks and end mill holders of the matching bore size.

Key Features

• 0.02 inch corner radius reduces edge chipping and stress risers during interrupted cuts
• AlTiN+ coating resists heat buildup for extended tool life in high-speed and dry cutting
• 4-flute, right-hand spiral flute geometry for improved surface finish and chip flow
• Centercutting design permits direct plunge entry without pre-drilled pilot holes
• Micrograin solid carbide substrate for consistent hardness and wear resistance
• Stub-length proportions maximize rigidity and reduce deflection in tight setups

Compatibility

Designed as a direct-fit replacement for Series 6/44 corner radius end mills with a 3/16 inch straight cylindrical shank compatible with standard ER collet chucks and end mill holders of matching bore size.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully into the collet or holder to the recommended gauge-line depth and torque the retention nut per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut.
