Harvey Tool 893062-C6 Ball End Mill 1/16 in 4 Flute Carbide

Product Description

The HARVEY TOOL 893062-C6 is a 4-flute solid carbide ball end mill engineered for high-temperature alloy machining. It carries a 1/16 inch (0.062 inch) cutting diameter with a 0.1860 inch reach length and a 1-1/2 inch overall length. The AlTiN Nano PVD coating provides heat and oxidation resistance suited to the extreme cutting temperatures generated when working superalloys and titanium. A 34-degree variable helix geometry reduces harmonic chatter and improves chip evacuation, making this tool appropriate for aggressive roughing strategies in difficult materials. Licensed machinists and tool-and-die professionals specify this geometry when surface finish and tool life in exotic alloys are both priorities.

This end mill is designed for primary use in superalloys and titanium (ISO material code S) and is also rated for secondary applications in steel, stainless steel, cast iron, and hard materials (ISO codes P, M, K, and H). Typical install scenarios include 3-axis and 5-axis CNC milling centers running high-temp alloy aerospace components, medical device parts, and precision die work. The single-end, straight-cylindrical 1/8 inch shank fits standard ER and end mill holders without adapters.

Key Features

• Variable helix design at 34 degrees reduces chatter and improves stability in tough alloy cuts
• AlTiN Nano PVD coating delivers high heat resistance and extended tool life in superalloys and titanium
• Solid carbide construction maintains rigidity at small diameters where high-speed steel would deflect
• Ball nose geometry enables contoured 3D surface milling and full-radius profiling
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility
• Rated for roughing material removal in high-temp alloys per series designation

Compatibility

Designed as an OEM-specified solid carbide ball end mill for CNC milling applications in superalloys, titanium, steel, stainless steel, cast iron, and hard materials. Compatible with standard 1/8 inch straight-cylindrical shank toolholders.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with CNC tooling setup and high-temperature alloy cutting parameters. Secure the 1/8 inch straight shank in a clean, undamaged collet or end mill holder and verify runout before engaging the cut. Power down and lock out the spindle before changing tooling. Do not exceed the tool reach or axial depth of cut beyond what the machine and workholding setup can rigidly support, as deflection at small diameters can cause tool breakage.
