Harvey Tool 32215 Ball End Mill 0.015 in 3 Flute Solid Carbide

Product Description

The HARVEY TOOL 32215 is a miniature solid carbide ball end mill designed for precision finishing operations in hard materials. With a 0.015-inch mill diameter, a 0.078-inch length of cut, and a 3-flute variable-helix geometry, this tool removes material cleanly at small scale without deflection or chatter. The 0.0075-inch nose radius produces accurate ball-end profiles. It is intended for machinists and tooling technicians running CNC milling operations where tight tolerances and fine surface finish are required on hardened steels, stainless steel, and cast iron.

This end mill is sized for miniature and micro-machining applications in mold-making, die work, medical component manufacturing, and precision part production. The long-flute configuration and 2.5-inch overall length allow access to deeper cavities and contoured features that standard-length tools cannot reach. Suitable for use in vertical machining centers and high-speed CNC spindles capable of holding a 0.125-inch straight cylindrical shank. Primary workpiece materials are hard materials, with secondary suitability for steel, stainless steel, and cast iron.

Key Features

• 0.015-inch ball diameter with 0.0075-inch nose radius for precise profile milling
• 3-flute variable-helix design reduces harmonic vibration during light finishing cuts
• Solid carbide construction provides rigidity and wear resistance in hard and abrasive materials
• Long-flute series with 0.078-inch reach length for deep-cavity and contour access
• Bright uncoated finish suitable for applications where coating adhesion or material reactivity is a concern
• Right-hand cut and right-hand flute direction, single end configuration

Compatibility

Designed for CNC milling machines accepting a 0.125-inch straight cylindrical shank. Intended for finishing operations in hard materials, steels, stainless steels, and cast irons per Harvey Tool series designation Miniature End Mills - Ball - Long Flute.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Secure the shank in a precision collet or end mill holder rated for the shank diameter tolerance class h6 to maintain runout control. Ensure the spindle and tool holder are clean and free of chips before seating the tool. At this diameter, tool breakage risk is high if feed rates, speeds, or depth of cut are not dialed in carefully for the workpiece material.
