Kennametal 2658446 Square End Mill 0.5in 3 Flute Carbide

Product Description

The KENNAMETAL 2658446 is a solid carbide square end mill designed for high-performance milling in metal cutting and general machining applications. With a 0.5 inch cutting diameter, a 2 inch length of cut, and a 3-flute geometry, this end mill is built for efficient material removal with a right-hand cut and right-hand flute orientation. The micrograin carbide construction delivers hardness and wear resistance suited to demanding cutting conditions. A 37-degree high helix angle promotes chip evacuation and surface finish quality. This tool is center-cutting, allowing plunge entry into the workpiece. It is typically installed and operated by machinists and CNC technicians in job shop, aerospace, automotive, and general manufacturing environments.

The 2658446 is part of the SFRHEC series, which is configured for extra coarse pitch applications. The 0.5 inch shank diameter matches standard ER and side-lock toolholders common in vertical and horizontal machining centers as well as manual mills. The bright uncoated finish makes it well suited for applications where coating interaction with the workpiece material or cutting fluid is a concern. Single-end configuration means the tool is run from one end only, with a 4.5 inch overall length providing clearance in most standard setups.

Key Features

• Solid micrograin carbide construction for hardness and extended tool life
• 3-flute, extra coarse pitch geometry for aggressive material removal
• 37-degree high helix angle promotes chip evacuation and reduces heat buildup
• Center-cutting design enables direct plunge and ramp entry
• Right-hand cut and right-hand flute orientation for standard spindle use
• Bright uncoated finish suitable for a wide range of workpiece materials and cutting fluids

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 0.5 inch shank toolholders used in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before inserting the end mill. Verify shank engagement depth meets the toolholder manufacturer minimum pull-out resistance specification. Do not exceed the manufacturer recommended cutting parameters for the material being machined.
