Harvey Tool 989832 Ball End Mill 1/2 in 3 Flute Carbide

Product Description

The HARVEY TOOL 989832 is a solid carbide ball end mill engineered for high-performance milling in aluminum alloys, non-ferrous metals, steel, stainless steel, and cast iron. It features a 1/2 inch cutting diameter, a 1-1/2 inch length of cut, and a 42-degree variable helix angle that reduces chatter and improves chip evacuation during aggressive material removal. With three flutes and a spiral flute geometry, it is suited for roughing operations where chip load and cutting efficiency are priorities. Machinists and tool-and-die professionals use this end mill in CNC machining centers where surface finish and dimensional accuracy are critical.

This end mill is designed for material-specific applications, particularly aluminum alloys and non-ferrous metals, though its carbide substrate also handles steel, stainless steel, and cast iron. It is part of the HARVEY TOOL Variable Helix End Mills for Aluminum Alloys - Ball series. The single-end, straight-cylindrical 1/2 inch shank makes it compatible with standard ER and end mill holders. It is used in both roughing passes and contour work where the ball nose profile is required for 3D surface work.

Key Features

• Variable helix angle at 42 degrees reduces harmonics and chatter during deep cuts
• 3-flute spiral geometry optimized for efficient chip evacuation in aluminum and non-ferrous materials
• Ball nose profile with 0.25 inch nose radius enables 3D contouring and profiling operations
• Solid carbide construction provides rigidity and wear resistance across a broad range of workpiece materials
• Bright/uncoated finish suitable for use with or without coolant in standard machining environments
• Right-hand cut and right-hand flute direction; single-end design with no extended reach

Compatibility

Designed for use in CNC machining centers with standard straight-cylindrical shank tool holders. Compatible with workpiece materials including aluminum alloys, non-ferrous metals, steel, stainless steel, and cast iron per ISO material codes P, M, K, and N. Part of the HARVEY TOOL Variable Helix End Mills for Aluminum Alloys - Ball series.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or changing tooling. Use a calibrated torque wrench and the appropriate collet or end mill holder to secure the 1/2 inch shank to the specified clamping torque for the holder in use. Verify runout with a dial indicator after tool installation to maintain dimensional accuracy and tool life.
