Value Collection 723-4577 Roughing End Mill 1 in 3 Flute Cobalt

Product Description

The VALUE COLLECTION 723-4577 is a single-end roughing end mill designed for aggressive material removal in milling applications. Built from M42 cobalt high-speed steel with a bright, uncoated finish, it measures 1 inch in diameter with a 1-inch shank diameter, a 3-inch length of cut, and a 5.5-inch overall length. The 3-flute geometry paired with a high helix style produces faster chip evacuation and lower cutting forces compared to standard 4-flute designs. This tool is center-cutting, allowing plunge entry directly into the workpiece. Installed by machinists and tool-and-die professionals, it suits manual mills and CNC machining centers running ferrous and non-ferrous materials at elevated feed rates.

This roughing end mill is suited for roughing passes in general-purpose milling on ferrous metals, stainless steels, and high-temperature alloys where cobalt tooling provides thermal resistance and edge retention. Its right-hand cut and right-hand flute direction follow standard milling conventions. The single-end configuration concentrates tool mass at one cutting end, which benefits rigidity in deeper-reach applications. No extended reach geometry is present, keeping the tool profile compact for standard knee-mill and machining-center setups.

Key Features

• M42 cobalt high-speed steel construction for heat and wear resistance
• 3 flutes with high helix style for efficient chip evacuation and reduced cutting forces
• Center-cutting design allows direct plunge entry without a pre-drilled hole
• 1-inch diameter with 1-inch shank for direct collet or end mill holder mounting
• 3-inch length of cut accommodates moderate-depth roughing passes
• Right-hand cut and right-hand flute direction compatible with standard spindle rotation

Compatibility

Designed as an OEM-style replacement or standard tooling option for manual knee mills and CNC machining centers accepting 1-inch shank end mill holders or ER collet systems.

Installation Notes

Installation is performed by a qualified machinist. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the holder to the recommended engagement depth per your machine tool manufacturer guidelines. Verify spindle rotation direction matches the right-hand cut specification before initiating a cut.
