Kennametal 5051858 Square End Mill 0.5in 3-flute Carbide

Product Description

The KENNAMETAL 5051858 is a solid carbide square end mill engineered for precision milling in metalworking and machining applications. Built from micrograin carbide, this single-end tool features a 0.5-inch cutting diameter, a 3-inch length of cut (LOC), and a right-hand spiral flute geometry with a 37-degree helix angle. The centercutting design allows direct plunge entry into the workpiece. Three flutes provide a balance of chip evacuation and surface finish quality. This tool is supplied uncoated (bright finish) and is intended for installation in CNC machining centers, knee mills, and manual milling machines by machinists and tool-and-die professionals.

The 5051858 is suited for peripheral and slot milling operations in ferrous and non-ferrous materials where tight tolerances are required. The 0.5-inch shank diameter provides secure tool holding in standard ER and straight-bore collet chucks. The 5-inch overall length (OAL) allows access to moderate-depth features. The AADE series designation identifies this as a standard-reach, general-purpose geometry within the KENNAMETAL solid carbide end mill lineup. Applications include profiling, contouring, pocketing, and full-slot milling.

Key Features

• Solid micrograin carbide construction for wear resistance and edge stability
• 37-degree right-hand spiral helix for efficient chip flow
• Centercutting capable for direct plunge milling
• Uncoated bright finish suitable for a broad range of base materials
• Shank diameter tolerance of +0.00000/-0.00043 inches for precise tool holding
• Mill diameter tolerance of +0.000/-0.002 inches

Compatibility

Designed as a standard 0.5-inch shank end mill compatible with ER collet chucks, straight-bore tool holders, and other standard milling tool-holding systems that accept a 0.5-inch round shank.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully powered down and locked before changing tooling. Seat the shank fully into the collet or tool holder to the recommended engagement depth before torquing the retention nut. Verify runout with a dial indicator after installation, as excessive runout will accelerate tool wear and reduce surface finish quality.
