Kennametal 3658833 Corner Radius End Mill 1/2 in 3 Flute Carbide

Product Description

The KENNAMETAL 3658833 is a solid carbide corner radius end mill designed for high-performance material removal in non-ferrous metal applications. It features a 1/2-inch diameter, a 1-1/4-inch length of cut, and a 0.03-inch corner radius that reduces stress concentration at the cutting edge and improves surface finish. With 3 flutes and a high-helix spiral geometry, the tool promotes efficient chip evacuation and smooth cutting action. This is a single-end, centercutting design, meaning it can plunge directly into workpiece material. It is suited for machinists and toolroom professionals working on CNC mills and machining centers.

This end mill is intended for use in non-ferrous metal machining, including aluminum, copper, brass, and similar materials where aggressive material removal and fine edge geometry are required. The coarse pitch and submicron carbide grade make it well suited for roughing passes in production and job-shop environments. It mounts in standard straight-bore end mill toolholders with a 1/2-inch bore. The 3-inch overall length provides adequate reach for most standard milling setups without sacrificing rigidity.

Key Features

• Solid submicron carbide construction for rigidity and wear resistance in non-ferrous cutting
• 0.03-inch corner radius reduces edge chipping and improves corner durability
• 3-flute, high-helix spiral geometry promotes efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece material
• Bright/uncoated finish optimized for non-ferrous metals where coating adhesion is not required
• Coarse pitch, right-hand flute and cutting direction for standard CNC milling operations

Compatibility

Designed for use with standard straight-bore end mill toolholders accepting a 1/2-inch shank diameter. Part of the KENNAMETAL AADE series, intended for non-ferrous metal roughing applications on CNC mills and machining centers.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping specifications. Always ensure the machine spindle is fully stopped and locked out before changing tooling. Verify runout with a dial indicator after seating the shank in the toolholder to confirm concentricity before operation. Coolant-through is not supported on this tool, so external coolant or air blast should be directed at the cutting zone as needed.
