Kennametal 3658902 Corner Radius End Mill 3/8 in 2 Flute

Product Description

The KENNAMETAL 3658902 is a solid carbide corner radius end mill designed for precision milling in non-ferrous metal applications. It features a 3/8-inch mill diameter, a 0.03-inch corner radius, and a 1-1/2-inch length of cut, making it well-suited for profiling and slotting operations where edge integrity and surface finish matter. The tool is centercutting, right-hand cut, right-hand flute, and carries a bright/uncoated finish from the AADF series. Submicron carbide grade provides the hardness and wear resistance needed for consistent tool life in aluminum, copper, and similar non-ferrous workpiece materials.

This end mill is intended for use in CNC machining centers and manual milling machines where non-ferrous metal stock is the primary workpiece material. It is classified as a roughing tool with a coarse pitch and high helix style, supporting efficient chip evacuation in softer, gummy materials. The long-length geometry, with a 4-inch overall length and 3/8-inch straight cylindrical shank, suits deeper reach applications. It is noted for use with HC-HSK Form A toolholding systems.

Key Features

• Solid submicron carbide construction for durability in non-ferrous metal cutting
• 0.03-inch corner radius reduces stress concentration and extends tool life at cutting edges
• Centercutting design allows plunge entry into workpiece material
• High helix, coarse pitch flute geometry promotes chip evacuation in aluminum and similar materials
• Bright/uncoated finish suited to non-ferrous applications where coating adhesion is unnecessary
• 2-flute configuration maximizes chip clearance in softer materials

Compatibility

Designed for use with HC-HSK Form A toolholding systems. Intended for non-ferrous metal workpiece materials as the primary application.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the end mill. Use an appropriate collet or toolholder that matches the 3/8-inch straight cylindrical shank diameter and confirm runout before cutting. Follow shop-standard feeds, speeds, and depth-of-cut guidelines for the specific workpiece material.
