Harvey Tool 13945 Square End Mill 0.045 in 2 Flute Carbide

Product Description

The HARVEY TOOL 13945 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 0.045-inch cutting diameter and a 1.7 mm (0.067 inch) length of cut, this tool is built for fine detail work in hardened materials, mold components, and intricate part features. The 2-flute configuration and 30-degree right-hand helix promote efficient chip evacuation in confined cutting zones. A bright, uncoated finish keeps the tool at its true carbide hardness and suits a broad range of ferrous and non-ferrous materials. Machinists and tool-and-die professionals rely on this style of micro end mill for CNC milling operations where dimensional accuracy is critical.

This end mill is suited for small-feature milling in CNC machining centers and manual mills handling detailed work in metals, composites, and engineering plastics. The 1/8-inch (0.125-inch) shank diameter fits standard collets and end mill holders commonly found in tool rooms, mold shops, and precision job shops. At 1.5 inches overall length, the 13945 maintains rigidity and minimizes deflection, which is essential when cutting at diameters this small. It is a single-end, center-cutting tool, meaning it can be used for plunge cuts as well as peripheral milling passes.

Key Features

• 0.045-inch cutting diameter for micro and fine-detail milling operations
• Solid carbide construction for hardness, wear resistance, and thermal stability
• 2-flute design promotes chip clearance in small, confined cuts
• 30-degree right-hand helix for smooth cutting action and reduced chatter
• Center-cutting geometry allows direct plunge entry into workpiece material
• Bright, uncoated finish compatible with a wide range of workpiece materials

Compatibility

Designed as a standard replacement-style solid carbide square end mill for use in CNC machining centers and manual mills equipped with 1/8-inch collets or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist familiar with toolholder torque procedures and runout inspection. Always secure the shank fully within the collet or holder to the manufacturer-recommended engagement depth before beginning any cut. Inspect the cutting edges under magnification before use, as micro end mills at this diameter are sensitive to edge chipping. Follow all machine guarding and PPE requirements per your facility and applicable OSHA standards when operating CNC or manual milling equipment.
