Kennametal 3658841 Corner Radius End Mill 0.5in 3 Flute Carbide

Product Description

The KENNAMETAL 3658841 is a solid carbide corner radius end mill designed for material removal in non-ferrous metal applications. It carries a 0.5 inch mill diameter with a 0.06 inch corner radius, a 2.5 inch length of cut, and a 5 inch overall length. The three-flute, right-hand spiral geometry runs at a high helix angle of 37 degrees and is left in a bright, uncoated finish suited to the submicron carbide grade. The straight cylindrical shank measures 0.5 inches in diameter. This is a single-end, centercutting tool built for extra-long reach roughing passes in non-ferrous workpiece materials.

The 3658841 belongs to the KENNAMETAL AADE series, which targets high-performance roughing in non-ferrous metals such as aluminum and copper alloys. The extra-long length of cut makes it well suited for deep-pocket milling, profiling, and contouring operations where standard-length tooling cannot reach. It is intended for use with standard end mill toolholders in CNC machining centers and manual mills running right-hand cutting direction. The coarse pitch and high helix promote chip evacuation in gummy, stringy materials common to this workpiece category.

Key Features

• 0.06 inch corner radius reduces stress concentration at the cutting edge and improves surface finish in pocket corners
• Submicron solid carbide grade delivers edge strength and wear resistance in non-ferrous materials
• 37-degree high helix promotes efficient chip evacuation and reduces heat buildup
• Extra-long 2.5 inch length of cut enables deep-pocket and extended-reach machining
• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• Bright, uncoated finish maintains sharp edge geometry and is compatible with cutting fluids used in aluminum machining

Compatibility

Designed for use with standard end mill toolholders. Primary workpiece material is non-ferrous metal. Part of the KENNAMETAL AADE series.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the toolholder is clean and free of debris before seating the shank; the straight cylindrical shank requires proper collet or end mill holder engagement to the specified depth. Confirm spindle direction is set to right-hand rotation before operation. Review applicable machine tool documentation and shop safety standards before running at depth of cut.
