Harvey Tool 74362-C3 Ball End Mill 0.062 in 4 Flute Carbide

Product Description

The HARVEY TOOL 74362-C3 is a miniature solid carbide ball end mill designed for precision milling in steel, stainless steel, and cast iron. With a 0.062-inch cutting diameter and a 30-degree helix angle, it delivers a combination of roughing and finishing capability in a single-end configuration. The AlTiN PVD coating improves heat resistance and extends tool life in ferrous materials. Four helical flutes provide efficient chip evacuation in tight-tolerance slots, contours, and pockets. This tool is used by machinists and tool-and-die professionals working on CNC vertical machining centers and similar equipment.

This end mill is suited for small-feature work in production and prototype environments. Its 0.186-inch reach length and 1.5-inch overall length make it appropriate for shallow-to-moderate depth passes where rigidity matters. The 0.125-inch straight cylindrical shank fits standard ER collet chucks and end mill holders common in CNC setups. Primary workpiece materials include steel, stainless steel, and cast iron, making it well matched to ferrous component machining in aerospace, mold-and-die, and general metalworking applications.

Key Features

• 0.062-inch ball nose diameter with a 0.031-inch nose radius for precise contour and 3D surface work
• AlTiN PVD coating provides elevated heat resistance for dry or near-dry cutting in ferrous materials
• 4 helical right-hand flutes support both roughing and finishing passes
• 30-degree helix angle balances cutting forces and chip flow in steel and stainless steel
• Solid carbide construction maintains rigidity and dimensional stability at miniature diameters
• Standard length geometry with no extended reach or chipbreaker for maximum core strength

Compatibility

Rated for primary use in steel, stainless steel, and cast iron (material codes P, M, and K). Fits 0.125-inch straight-cylindrical shank toolholders including ER collet chucks. No coolant-through capability; intended for external or flood coolant delivery.

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC tooling setup and runout tolerance requirements. Ensure the spindle and toolholder are clean and free of debris before seating the shank. Verify collet chuck torque and tool projection length before initiating a cut. At miniature diameters, even slight runout significantly reduces tool life and surface finish quality, so confirm TIR with a dial indicator before production runs.
