Harvey Tool 59462-C3 Ball End Mill 1/16 in 3 Flute Altin

Product Description

The HARVEY TOOL 59462-C3 is a miniature solid carbide ball end mill designed for precision milling in steel, stainless steel, and cast iron. With a 1/16 inch (0.0620 inch) cutting diameter and a 3/32 inch length of cut, this stub-flute, long-reach tool delivers both roughing and finishing capability in tight geometries. The AlTiN (aluminum titanium nitride) PVD coating improves heat resistance and tool life in ferrous materials. Three flutes and a 30-degree right-hand helix balance chip evacuation with surface finish quality. A 1/8 inch straight-cylindrical shank fits standard collet chucks used across CNC machining centers and manual mills alike.

This end mill is built for miniature and intricate milling work where standard tooling cannot reach. The extended reach design — 1-1/4 inch reach length and 1.157 inch neck length — makes it well suited for deep pocket milling, rib machining, and contour work in mold and die, medical component, and precision aerospace applications. It operates as a single-end tool with right-hand cutting direction. Machinists working ferrous alloys, hardened steels, and cast iron will find the AlTiN coating particularly effective for maintaining edge integrity at elevated cutting temperatures.

Key Features

• 1/16 inch ball nose diameter with a nose radius of 0.0310 inch for precise contour and radius milling
• AlTiN PVD coating rated for steel, stainless steel, and cast iron applications
• Long-reach, stub-flute geometry — 1-1/4 inch reach with 3/32 inch length of cut
• 3-flute, 30-degree right-hand spiral helix for balanced chip removal and finish quality
• Solid carbide construction for rigidity and dimensional stability in precision cuts
• Single-end design with straight-cylindrical 1/8 inch shank for standard collet compatibility

Compatibility

Designed for use in CNC machining centers and mills accepting a 1/8 inch straight-cylindrical shank. Recommended for roughing and finishing operations in steel, stainless steel, and cast iron workpiece materials as specified by the manufacturer.

Installation Notes

Installation is performed by machining professionals using a collet or end mill holder rated for 1/8 inch shank tooling. Verify collet runout before seating the tool — excessive runout accelerates wear on miniature-diameter end mills. Confirm spindle RPM and feed rate parameters are appropriate for a 1/16 inch diameter carbide tool before engaging the cut. Do not use coolant through this tool; it is not designed for through-spindle coolant delivery.
