Harvey Tool 826908-C3 Square End Mill 1/8 in 4 Flute Carbide

Product Description

The HARVEY TOOL 826908-C3 is a solid carbide square end mill designed for high-performance milling in ferrous and nonferrous materials. With a 1/8 inch cutting diameter, 1 inch length of cut, and four right-hand flutes, it delivers clean, accurate profiles in slot milling, contouring, and finishing passes. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. An aluminum titanium nitride (AlTiN) coating extends tool life in elevated-temperature applications. This end mill is a single-end, center-cutting design, allowing plunge entry as well as lateral cutting, making it a versatile choice for precision machining operations.

Suited for use in CNC machining centers, mill-drill setups, and manual knee mills, this end mill fits applications where a small-diameter, full-length carbide tool is required. Its 1/8 inch shank diameter allows direct mounting in standard collet chucks, end mill holders, and shrink-fit tooling without adapters. The AlTiN coating makes it a practical choice for cutting alloy steels, stainless steels, titanium, and hardened materials where heat buildup is a concern. Machinists and tool-and-die professionals working in precision mold, die, and aerospace component production will find this size and geometry appropriate for tight-tolerance work.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN coating for extended tool life at elevated cutting temperatures
• 4 right-hand flutes with right-hand cutting direction for efficient chip removal
• 30-degree helix angle reduces cutting forces and improves surface finish
• Center-cutting geometry allows direct plunge entry into workpiece material
• 1/8 inch shank matches cutting diameter for straightforward collet mounting

Compatibility

Designed as a direct-fit replacement or standard tooling selection for any machine spindle accepting a 1/8 inch collet or end mill holder. No specific OEM model compatibility was stated in the product data.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the collet, holder, and spindle are clean and free of chips or runout before seating the shank. Verify spindle RPM, feed rate, and depth of cut against the tool manufacturer's recommended cutting parameters for the workpiece material before starting the cut. Never exceed the rated length of cut, and avoid side loads that exceed the tool diameter to prevent deflection or breakage.
