Harvey Tool 826862 Square End Mill 1/16 in 4 Flute Carbide

Product Description

The HARVEY TOOL 826862 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 0.0625-inch cutting diameter and a 0.5-inch length of cut, this tool removes material cleanly in small-profile features such as slots, pockets, and contours. The 4-flute geometry and 30-degree helix angle improve chip evacuation and surface finish compared to 2-flute tools. The bright, uncoated finish suits a broad range of ferrous and non-ferrous materials without added coating cost. This end mill is a single-end tool with right-hand cut and right-hand flute orientation. Licensed machinists and CNC operators are the primary users.

This end mill is suited for CNC machining centers and manual mills handling small-feature work where dimensional accuracy is critical. The 0.125-inch shank diameter fits standard collets sized for 1/8-inch tooling. At 2.5 inches overall length, it reaches into moderate-depth setups without excessive overhang. Typical applications include die and mold work, prototype machining, medical components, and precision aerospace parts where small-diameter tooling is required.

Key Features

• 0.0625-inch cutting diameter for fine-detail and small-feature milling
• Solid carbide construction for rigidity and wear resistance
• 4-flute design improves finish quality and feed rate potential
• 30-degree helix angle promotes efficient chip flow
• Centercutting capability allows plunge entry into workpieces
• Right-hand cut and right-hand flute, standard CNC orientation
• Bright, uncoated finish compatible with a wide range of workpiece materials

Compatibility

Designed for use in CNC machining centers and manual mills equipped with collets or tool holders accepting a 1/8-inch shank diameter.

Installation Notes

Installation requires a clean, properly sized collet or end mill holder rated for 1/8-inch shank tooling. Ensure the machine spindle is fully stopped and the tool path is programmed before engaging the workpiece. Verify runout with a dial indicator after seating the tool, as small-diameter carbide end mills are sensitive to collet concentricity. Follow the tool manufacturer and machine builder guidelines for speed and feed parameters appropriate to the workpiece material.
