Harvey Tool 72047 Square End Mill 3/64 in 2 Flute Carbide

Product Description

The HARVEY TOOL 72047 is a miniature square end mill designed for precise milling operations in tight geometries. Built from solid carbide, it delivers the rigidity and wear resistance required for cutting ferrous and non-ferrous materials at small diameters. The 72047 measures 0.047 inches in cutting diameter with a 9/64-inch (0.141 inches) length of cut and a 1/8-inch shank diameter, making it well suited for fine detail work, slotting, and profiling in die, mold, and precision component machining. The 30-degree helix angle promotes smooth chip evacuation, and the centercutting geometry allows plunge entry into the workpiece.

This end mill is intended for use in CNC machining centers, high-speed spindles, and manual knee mills capable of holding close tolerances at micro diameters. Typical applications include mold cavity finishing, micro-slot milling, and detail profiling in aluminum, brass, tool steel, and similar materials. Right-hand cut and right-hand flute orientation follow standard industry convention. The uncoated solid carbide construction makes it a practical choice when coatings are unnecessary or when the application calls for re-sharpening.

Key Features

• 0.047-inch (3/64-inch) cutting diameter for fine detail and micro-milling applications
• Solid carbide construction for superior rigidity and tool life at small diameters
• 30-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute - standard CNC and manual mill orientation
• Uncoated finish suitable for a broad range of materials and re-sharpenable

Compatibility

Designed as a replacement-style solid carbide square end mill for CNC machining centers and manual mills equipped with 1/8-inch collets or matching tool holders.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the 1/8-inch shank fully into the collet or tool holder and torque the retention nut per the machine or toolholder specification. At micro diameters, run-out control is critical - verify TIR at the collet before production cuts to avoid premature tool breakage.
