Harvey Tool 802662 Square End Mill 1/16 in 4 Flute Carbide

Product Description

The HARVEY TOOL 802662 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 1/16-inch (0.0625-inch) cutting diameter and four flutes, it delivers smooth chip evacuation and consistent surface finishes in ferrous and non-ferrous materials. The 30-degree helix angle improves cutting efficiency and reduces chatter. At 2.5 inches overall length with a 5/8-inch length of cut, this end mill is well-suited for work requiring extended reach in a small-diameter tool. It is centercutting, allowing plunge entry directly into the workpiece. The 1/8-inch shank diameter fits standard collets and tool holders commonly found in CNC machining centers and manual mills.

This end mill is used in precision machining environments where small-diameter milling is required, including aerospace, medical device, mold and die, and general metalworking applications. Right-hand cut and right-hand flute geometry follows standard tooling conventions, making it a straightforward drop-in for most CNC and manual setups. The uncoated carbide substrate is appropriate for a range of materials and can be used with or without coolant depending on the application and shop practice.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• Four flutes with 30-degree helix angle for efficient chip removal and reduced cutting forces
• Centercutting geometry allows direct plunge milling without pre-drilling
• Right-hand cut, right-hand flute — standard orientation for CNC and manual mill setups
• 1/8-inch shank diameter fits widely available collets and tool holders
• Uncoated finish suitable for use with standard cutting fluids or dry machining

Compatibility

Designed as a replacement-style solid carbide square end mill for use in any CNC machining center or manual vertical mill equipped with a 1/8-inch collet or tool holder accepting a 1/8-inch shank.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Power down the spindle and confirm the machine is in a safe state before inserting or removing tooling. Seat the shank fully into the collet to the recommended gauge depth and tighten to the tool holder specification using the appropriate spanner wrench. Inspect the end mill for chips or cracks before use, and do not exceed the manufacturer-rated speeds and feeds for the workpiece material.
