Harvey Tool 956825-C3 Square End Mill 0.025 in 4 Flute Carbide

Product Description

The HARVEY TOOL 956825-C3 is a solid carbide square end mill designed for high-precision milling in tight-tolerance applications. With a 0.0250-inch cutting diameter and a 0.075-inch length of cut, this tool is built for fine detail work in ferrous and non-ferrous materials. The 4-flute configuration paired with a 30-degree helix angle promotes efficient chip evacuation while maintaining a smooth surface finish. An AlTiN coating adds thermal resistance and extends tool life in harder materials. This end mill is installed and operated by machinists and tool-and-die professionals working on CNC milling centers and manual mills.

This end mill suits residential shop, job shop, and production floor environments where small-diameter precision cutting is required. The extended reach design, with a 0.125-inch reach length and a 0.125-inch shank diameter, allows access to recessed features and narrow slots. It is center-cutting, enabling direct plunging into material. Right-hand cut and right-hand flute direction make it compatible with standard CNC and manual milling setups. Typical applications include micro-slot milling, profiling, and contour work in tool steels, stainless, and aluminum.

Key Features

• 0.0250-inch cutting diameter for fine detail and micro-milling work
• Solid carbide construction for rigidity and wear resistance
• AlTiN coating provides elevated heat resistance and longer tool life
• 30-degree helix angle promotes smooth cutting action and chip flow
• Center-cutting design allows direct plunge entry into workpiece
• Extended reach with 0.125-inch reach length for access to recessed features

Compatibility

Designed as a standard replacement-style solid carbide square end mill for CNC milling centers and manual mills accepting a 0.125-inch (1/8-inch) shank diameter collet or end mill holder.

Installation Notes

Installation is performed by a qualified machinist. Ensure the milling machine spindle is fully powered down and locked out before loading or removing any end mill. Secure the shank fully within the collet or tool holder to the manufacturer-specified engagement depth before tightening. At 0.0250-inch diameter, this is an extremely fragile tool — use appropriate feed and speed parameters for the material and avoid side loads that exceed the tool's deflection limits.
