Harvey Tool 13915 Square End Mill 1/64 in 2 Flute Carbide

Product Description

The HARVEY TOOL 13915 is a solid carbide square end mill engineered for precision milling in tight-tolerance applications. With a 1/64 inch (0.0150 inch) cutting diameter and a 0.022 inch length of cut, this tool is built for micro-scale work where accuracy and tool rigidity are critical. The 1/8 inch shank diameter and 1-1/2 inch overall length make it compatible with standard collet chucks and small-footprint machining centers. Two flutes provide a balance of chip evacuation and wall finish at this scale. The 30-degree helix angle promotes smooth cutting action, and the centercutting geometry allows plunge entry into the workpiece.

This end mill is suited for finishing and light profiling operations in ferrous and non-ferrous materials where part features are extremely small. Typical applications include mold and die detail work, medical device components, electronics hardware, and precision instrument parts. Machinists running high-speed machining centers or CNC mills with capable spindle speeds will get the best results from this tool. The uncoated carbide substrate is appropriate for applications where coating buildup clearance is not acceptable or where re-sharpening is anticipated.

Key Features

• 0.0150 inch (1/64 inch) cutting diameter for micro-scale milling operations
• Solid carbide construction provides rigidity and wear resistance at small diameters
• 2-flute geometry balances chip clearance and surface finish
• 30-degree helix angle promotes smooth cutting and reduced cutting forces
• Centercutting design allows direct plunge entry
• Right-hand cut, right-hand flute configuration

Compatibility

Designed for use in CNC machining centers and manual mills equipped with 1/8 inch collets or collet chucks capable of holding small-diameter end mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Seat the shank fully into the collet and torque the collet nut according to the collet manufacturer's specification. At this diameter, runout control is critical — use a precision collet system and verify runout before cutting.
