Harvey Tool 34647 Square End Mill 3/64 in 3 Flute Carbide

Product Description

The HARVEY TOOL 34647 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 3/64 inch (0.047 inch) cutting diameter and a 0.071 inch length of cut, this tool is built for small-feature work where accuracy is critical. The three-flute geometry with a 30-degree helix angle balances chip evacuation with cutting efficiency. Center-cutting capability allows direct plunging into workpiece material. This end mill is uncoated and suited for machinists and toolroom operators working with non-ferrous metals, plastics, and similar materials at small scales.

This end mill fits CNC machining centers and manual mills where a 1/8 inch shank is used. The 2.5 inch overall length provides enough reach for most small-part milling operations while maintaining rigidity at this diameter. The 3/8 inch reach length supports light profiling and slotting in shallow-to-moderate-depth features. Right-hand cut and right-hand flute orientation match standard spindle rotation on most machines. This tool is appropriate for precision shops, mold making, prototype work, and instrumentation manufacturing.

Key Features

• 3/64 inch (0.047 inch) cutting diameter for fine-feature milling
• Solid carbide construction for rigidity and wear resistance at small diameters
• Three-flute design with 30-degree helix for balanced cutting and chip flow
• Center-cutting geometry allows direct plunge entry
• Right-hand cut and right-hand flute for standard spindle compatibility
• Uncoated finish suited for non-ferrous and plastic workpiece materials

Compatibility

Designed for use in CNC machining centers and manual mills equipped with a 1/8 inch collet or toolholder. No specific compatible machine models were provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is in a safe, de-energized state before changing tooling. Seat the 1/8 inch shank fully and concentrically in the collet to minimize runout at this small diameter. At 3/64 inch diameter, even minor runout or side loading can cause tool breakage, so verify collet condition and clamping torque before operation.
