Harvey Tool 62878-C6 Square End Mill 5/64 in 5 Flute Carbide

Product Description

The HARVEY TOOL 62878-C6 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. With a 5/64 inch (0.0780 inch) cutting diameter and a 5/8 inch length of cut, this tool delivers tight tolerances in small-bore and detail work. Five flutes and a 44-degree variable helix geometry improve chip evacuation and reduce chatter, making it well suited for harder materials and finishing passes. An AlTiN coating adds heat resistance and surface hardness, extending tool life in ferrous and high-temp alloy cuts. Licensed machinists and CNC operators are the primary users of this end mill.

This end mill fits applications requiring a compact cutting diameter with a full 2-1/2 inch overall length for clearance in deeper setups. The 1/8 inch shank diameter suits standard collet and tool holder configurations used in vertical machining centers and CNC mills. Its right-hand cut and right-hand flute direction are consistent with conventional climb and conventional milling operations. The non-center-cutting design means it is intended for side milling, profiling, slotting, and peripheral cuts rather than plunge entry.

Key Features

• 5/64 inch (0.0780 inch) cutting diameter for fine detail and small-feature work
• 5 flutes with 44-degree variable helix for reduced chatter and improved chip flow
• AlTiN coating for elevated heat resistance in ferrous and high-temp alloy machining
• Solid carbide construction for rigidity and wear resistance
• 1/8 inch shank diameter compatible with standard collet systems
• Non-center-cutting, right-hand geometry for side milling and profiling operations

Compatibility

Designed for use in CNC vertical machining centers and manual mills equipped with 1/8 inch collets or tool holders; suitable for profiling, slotting, and peripheral milling in ferrous metals and high-temperature alloys.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine in a powered-down, locked-out state per OSHA lockout/tagout procedures. Ensure the collet and tool holder are clean and free of debris before seating the shank. Verify runout with a dial indicator before initiating a cutting program. Do not use this non-center-cutting end mill for plunge entry into a solid workpiece.
