Harvey Tool 14045 Square End Mill 0.045 in 4 Flute Carbide

Product Description

The HARVEY TOOL 14045 is a solid carbide square end mill designed for precision milling in tight-tolerance applications. With a 0.045-inch cutting diameter and a 0.067-inch length of cut, this tool is built for micro-milling work where dimensional accuracy is critical. The 4-flute geometry and 30-degree helix angle promote smooth chip evacuation and stable cutting action. The 1/8-inch shank diameter makes it compatible with standard collet systems used across CNC machining centers and high-speed spindles. Machinists and tool-and-die professionals working on small-feature workpieces will find this end mill suited for slotting, profiling, and pocketing operations requiring fine detail.

This end mill is intended for use in light-to-moderate material removal on small-scale features. The centercutting design allows plunge entry directly into the workpiece, expanding its versatility in CNC milling setups. At 1.5 inches overall length with a 0.045-inch diameter, it is well suited for fine detail work in mold making, die work, medical component machining, and precision prototype fabrication. The uncoated carbide construction is appropriate for applications where coating buildup or heat transfer into the substrate is a concern.

Key Features

• 0.045-inch cutting diameter for micro and fine-detail milling operations
• Solid carbide construction for rigidity and wear resistance in precision applications
• 4-flute configuration with 30-degree helix angle for smooth cutting and chip flow
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute geometry for standard CNC spindle compatibility
• Uncoated finish suitable for applications where substrate heat management is a priority

Compatibility

Designed as an OEM-style replacement-grade solid carbide square end mill for use in CNC machining centers and manual mills equipped with 1/8-inch collet or chuck systems accepting standard shank end mills.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling procedures. Ensure the spindle is fully powered down and at a complete stop before inserting or removing the end mill from the collet. Verify collet cleanliness and proper torque on the drawbar or collet nut before beginning a cut. At 0.045-inch diameter, this tool is extremely fragile — use appropriate feed and speed calculations for the specific workpiece material to avoid tool breakage.
