Harvey Tool 72045 Square End Mill 0.045 in 2 Flute Carbide

Product Description

The HARVEY TOOL 72045 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.0450-inch cutting diameter and a 0.135-inch length of cut, this tool is built for small-feature work where accuracy and rigidity are critical. The 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 1.5 inches overall length with a 0.125-inch shank diameter, it mounts into standard collets and tool holders used in CNC machining centers and manual mills. Installed by machinists and toolroom professionals, it ships in bright, uncoated finish ready for use.

This end mill is suited for light-to-medium milling passes on ferrous and non-ferrous materials in tight-tolerance applications. The 0.0450-inch diameter makes it appropriate for miniature slot milling, profiling, and detail work on small components. Its centercutting capability allows plunge entry into the workpiece. The 0.125-inch shank fits 1/8-inch collets commonly used on CNC routers, micro machining centers, and precision vertical mills used in mold, die, and prototype work.

Key Features

• 0.0450-inch cutting diameter for small-feature and miniature milling
• Solid carbide construction for rigidity and wear resistance at elevated speeds
• 30-degree helix angle promotes efficient chip evacuation and reduced chatter
• Centercutting design allows direct plunge entry into workpiece material
• Right-hand cut, right-hand flute configuration for standard spindle rotation
• Bright, uncoated finish suitable for a wide range of base materials

Compatibility

Designed as an OEM-style replacement or direct-use end mill compatible with 1/8-inch collet systems on CNC machining centers, CNC routers, and precision vertical mills requiring a 0.0450-inch square end mill.

Installation Notes

Installation should be performed by a qualified machinist familiar with tool holding and runout requirements. Ensure the spindle is fully powered down and at rest before inserting or removing the tool from the collet. Use an appropriately sized collet and tighten to the tool holder manufacturer's specified procedure to prevent tool pullout during cutting. Verify runout with a dial indicator before production use when working to tight tolerances.
