Harvey Tool 32308 Ball End Mill 1/8 in 3 Flute Carbide

Product Description

The HARVEY TOOL 32308 is a solid carbide, three-flute ball end mill designed for finishing operations in hard materials, steel, stainless steel, and cast iron. With a 1/8 inch cutting diameter and a 5/8 inch length of cut, this miniature end mill belongs to the Long Flute series, making it well suited for reaching into deeper pockets and profiled surfaces where standard-length tools fall short. The 20-degree variable helix geometry helps reduce chatter and improve surface finish during high-speed passes. At 0.02 pounds, the tool is light and precise, engineered for tight-tolerance work in demanding CNC applications.

This end mill is intended for use in CNC machining centers and high-speed milling setups where small-diameter, long-reach cutting is required. Its primary application is finishing passes on hard materials, including tool steels and stainless steel. The uncoated bright finish makes it a straightforward choice when coating is not required by the application or when the operator prefers an uncoated substrate. It is typically run by machinists in precision job shops, mold and die environments, and production machining operations requiring miniature tooling.

Key Features

• 1/8 inch cutting diameter with a matching 1/8 inch straight-cylindrical shank
• 5/8 inch length of cut for extended reach into pockets and contoured surfaces
• Three-flute variable helix design reduces chatter and improves surface finish
• Solid carbide construction provides rigidity and wear resistance in hard materials
• Single-end, right-hand cut with right-hand spiral flutes
• Bright/uncoated finish suitable for applications where coating is not specified

Compatibility

Designed as an OEM-style miniature ball end mill for use in CNC milling applications requiring a 1/8 inch shank and long-flute reach geometry. Part of the HARVEY TOOL Miniature End Mills - Ball - Long Flute series.

Installation Notes

Installation and use of this end mill should be performed by a qualified machinist familiar with CNC tooling setup and cutting parameters. Ensure the spindle and tool holder are clean and free of debris before seating the shank. Verify runout with a dial indicator before beginning cuts, as excessive runout accelerates wear on small-diameter carbide tools. Follow machine manufacturer guidelines and consult cutting data references for appropriate speeds, feeds, and depth of cut for the workpiece material.
