Harvey Tool 974247-C3 Ball End Mill 0.0469 in 2 Flute Carbide

Product Description

The HARVEY TOOL 974247-C3 is a single-end ball end mill designed for precision milling in hardened and abrasive materials. Built from solid carbide, it delivers the rigidity and wear resistance required for tight-tolerance work in die, mold, and detail machining. The cutting diameter measures 0.0469 inches (3/64 inches), with a 0.04 inch length of cut and an AlTiN coating that extends tool life under high-heat cutting conditions. The 1/8 inch shank fits standard collets and tool holders used in CNC machining centers and high-speed spindles. This tool is specified by machinists and tooling professionals working in aerospace, medical, and precision mold applications.

This end mill is suited for finishing and semi-finishing passes in ferrous metals, hardened steels, and heat-resistant alloys where a small-diameter ball profile is required. The right-hand flute direction and right-hand cutting geometry are standard for conventional CNC milling setups. The 0.0625 inch neck length and 0.0290 inch neck diameter allow access to tight pockets and detailed contours without deflection from the shank. Overall length is 1.5 inches, keeping the tool compact and stable at high RPM. Professional CNC machinists and toolroom operators are the primary installers and users of this tool.

Key Features

• Solid carbide construction for rigidity and wear resistance in hardened and abrasive materials
• AlTiN coating reduces heat buildup and extends tool life in ferrous and high-temp alloy cutting
• 0.0469 inch (3/64 inch) ball diameter for fine detail and small-radius contour work
• 2-flute geometry balances chip evacuation and cutting edge strength at small diameters
• Right-hand cut, right-hand flute — standard orientation for CNC machining centers
• Compact 1.5 inch overall length minimizes overhang and reduces vibration at high spindle speeds

Compatibility

Designed as an OEM-style solid carbide ball end mill compatible with standard 1/8 inch collets and tool holders on CNC machining centers and high-speed milling spindles.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom operator. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the 1/8 inch shank fully into the collet or tool holder and torque the retention mechanism per the tool holder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, especially at this diameter, as even minor runout will affect tool life and surface finish.
