Kennametal 6754936 Square End Mill 1 in 5 Flute Solid Carbide

Product Description

The KENNAMETAL 6754936 is a solid carbide square end mill engineered for high-performance material removal in aluminum and non-ferrous applications. Part of the KOR5 series, it features a 1 inch cutting diameter, 5 spiral flutes with a 35-degree helix angle, and a chipbreaker geometry that reduces cutting forces and improves chip evacuation. The single-end, right-hand cut configuration with a bright uncoated finish suits applications where coating compatibility with aluminum is a priority. At 5.5 inches overall length with a 3 inch length of cut, it provides reach suitable for deeper pocketing and profiling operations. Machining professionals and tool crib operators handling production aluminum work will find this a direct-specification tool.

This end mill is designed primarily for cutting aluminum and non-ferrous metals, where its uncoated solid carbide substrate and high helix angle promote free cutting and reduce built-up edge. The 1 inch shank diameter provides rigid clamping in standard end mill holders, collet chucks, or shrink-fit tooling. It is suited for CNC milling centers running high spindle speeds and aggressive feed rates typical of aluminum aerospace, automotive, and general machining operations. The KOR5 series geometry is optimized for finishing and semi-finishing passes in these material families.

Key Features

• Solid carbide construction, material grade K600, for rigidity and wear resistance in non-ferrous cutting
• 5 spiral flutes with 35-degree helix angle for efficient chip evacuation in aluminum
• Chipbreaker geometry reduces cutting forces and helps control chip length
• Bright uncoated finish compatible with aluminum and non-ferrous workpiece materials
• Right-hand cut, right-hand flute, single-end configuration
• Center-cutting capable, allowing plunge entry

Compatibility

Designed as an OEM-specification tool within the KENNAMETAL KOR5 series, optimized for aluminum and non-ferrous workpiece materials (ISO material code N). Fits standard 1 inch bore end mill holders, collet chucks, and shrink-fit toolholders used on CNC vertical and horizontal machining centers.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state per facility lockout procedures. Ensure the shank seating surface and toolholder bore are clean and free of chips or burrs before clamping. Torque toolholder fasteners according to the toolholder manufacturer specifications, not this tool. Verify runout with a dial indicator after clamping before initiating a cut to protect both the tool and the workpiece.
