Harvey Tool 13990 Square End Mill 0.09 in 2 Flute Carbide

Product Description

The HARVEY TOOL 13990 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 0.09-inch cutting diameter and a 0.135-inch length of cut, this tool is built for fine-detail work in tight tolerances. The two-flute geometry provides efficient chip evacuation and is well-suited for slotting, profiling, and peripheral milling operations. The 30-degree helix angle balances cutting forces and surface finish quality. The bright, uncoated finish makes it appropriate for use in a wide range of workpiece materials where coating interaction is a concern. Machinists and CNC operators are the primary users of this tool.

This end mill fits standard 1/8-inch shank tool holders and collet systems commonly found on CNC machining centers and manual mills. The 1.5-inch overall length keeps the tool rigid during operation, minimizing deflection at this small diameter. It is suited for precision work in mold making, die work, aerospace components, medical part machining, and other applications that require small-diameter, high-accuracy cutting tools. Its centercutting capability allows for plunge entry into the workpiece.

Key Features

• 0.09-inch cutting diameter for fine-detail and small-feature milling
• Solid carbide construction for rigidity and wear resistance
• 2-flute design promotes chip clearance in slotting and profiling cuts
• 30-degree right-hand helix angle for balanced cutting action
• Centercutting capable - supports plunge milling operations
• Bright/uncoated finish suitable for a broad range of material types

Compatibility

Designed for use in standard 1/8-inch shank collet chucks and tool holders on CNC machining centers and manual milling machines requiring small-diameter solid carbide end mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator familiar with small-diameter tooling. Ensure the machine spindle is fully powered down and locked out before loading or changing tooling. Secure the shank fully within the collet or tool holder to the recommended engagement depth to minimize runout and deflection. At this diameter, excess overhang or improper seating significantly increases the risk of tool breakage.
