Harvey Tool 14090-C3 Square End Mill 0.09 in 4 Flute Carbide

Product Description

The HARVEY TOOL 14090-C3 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.0900-inch cutting diameter and a 0.135-inch length of cut, this end mill is built for small-feature work where tight tolerances and sharp edges are critical. The 30-degree helix angle promotes efficient chip evacuation, and the AlTiN coating provides thermal resistance and hardness for extended tool life in ferrous and hardened materials. Four flutes deliver a balance of chip clearance and surface finish quality. The 0.125-inch shank fits standard 1/8-inch collets, and the 1.5-inch overall length suits compact setups and precision CNC applications.

This end mill is suited for finishing and profiling passes on small features in steel, stainless steel, cast iron, and similarly hard materials where an AlTiN-coated carbide tool performs at its best. Typical applications include slotting, side milling, and contouring on CNC machining centers and manual knee mills. The centercutting geometry allows for plunge entry, adding versatility in complex multi-operation programs.

Key Features

• 0.0900-inch cutting diameter for fine-detail and small-feature milling
• AlTiN coating for thermal and wear resistance in ferrous materials
• 30-degree helix angle promotes smooth cutting action and efficient chip removal
• Centercutting design allows direct plunge entry
• Four flutes for improved surface finish on finishing passes
• Solid carbide construction provides rigidity and dimensional stability

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with 1/8-inch collet systems. Suitable for machining ferrous metals, hardened steels, and similar materials where an AlTiN-coated solid carbide end mill is appropriate.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a safe, de-energized state. Seat the 0.125-inch shank securely in a matched collet or end mill holder and verify runout before cutting. Avoid overextending the tool beyond the recommended length of cut. Follow the tool manufacturer and machine tool builder guidelines for speeds, feeds, and depth of cut when programming or setting up cuts.
