Harvey Tool 12745 Square End Mill 0.045 in 3 Flute Carbide

Product Description

The HARVEY TOOL 12745 is a square end mill designed for precision milling operations in metal, composites, and other hard materials. It features a 0.0450-inch cutting diameter with a 0.225-inch length of cut, making it well-suited for fine detail work and tight-tolerance slot and profile milling. The tool is ground from solid carbide for rigidity and wear resistance. A 30-degree right-hand helix and right-hand cut geometry promote efficient chip evacuation and smooth cutting action. The bright, uncoated finish is standard for general-purpose carbide tooling. This end mill is installed and operated by machinists and tool-and-die professionals on CNC and manual milling equipment.

This end mill is used in applications requiring small-diameter, high-precision cuts. The 0.0450-inch diameter makes it appropriate for micro-milling, engraving, fine slot cutting, and detail work on small components. The 0.125-inch shank diameter fits standard 1/8-inch collets and tool holders common on CNC machining centers, mini mills, and precision benchtop equipment. The 2.5-inch overall length provides adequate clearance for most setups without sacrificing rigidity at this diameter. It is a single-end tool sold individually.

Key Features

• 0.0450-inch cutting diameter for precision micro-milling and fine detail work
• Solid carbide construction for rigidity and extended tool life compared to HSS
• 3-flute geometry balances chip load and surface finish in small-diameter applications
• 30-degree right-hand helix promotes efficient chip evacuation
• Centercutting design allows plunge entry into the workpiece
• Bright, uncoated finish suitable for general-purpose non-ferrous and ferrous milling

Compatibility

Designed for use with standard 1/8-inch collets and tool holders on CNC machining centers and manual milling equipment accepting square end mills with a 0.125-inch shank diameter.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully stopped and the machine in a safe, locked-out state. Ensure the collet and tool holder are clean and free of chips before seating the shank. Verify runout with a dial indicator after clamping, as even minor runout is critical at this cutting diameter. Do not exceed the recommended depth of cut for small-diameter carbide tooling, as solid carbide is brittle and susceptible to breakage under side load at this size.
