Harvey Tool 945578 Square End Mill 0.0780 in 3 Flute Carbide

Product Description

The HARVEY TOOL 945578 is a solid carbide square end mill engineered for precision milling in metalworking and machining applications. With a 0.0780-inch cutting diameter and a 0.125-inch shank diameter, this tool handles tight-tolerance slotting, profiling, and peripheral milling in small-envelope work. The 3-flute geometry paired with a 30-degree helix angle provides a balance of chip evacuation and cutting stability. At 2.5 inches overall length with a 0.117-inch length of cut, this end mill is suited for machinists and tooling technicians working in CNC milling environments where dimensional accuracy is critical.

This end mill is intended for use in CNC machining centers and manual milling machines where fine-feature work demands a small-diameter, extended-reach tool. The 0.312-inch reach length and center-cutting capability allow plunge entries and full-slot operations in confined areas. The bright, uncoated finish makes it suitable for a range of ferrous and non-ferrous materials where coating chemistry is not required. Tooling technicians and machinists performing precision work in mold making, die work, or complex part profiles will find this geometry appropriate for their needs.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• 0.0780-inch cutting diameter for fine-feature and small-envelope machining
• 3-flute design with 30-degree helix for efficient chip evacuation and smooth cutting action
• Center-cutting capable — supports direct plunge entry without pre-drilling
• Extended reach with 0.312-inch reach length for access in confined or deep features
• Bright, uncoated finish for broad material compatibility

Compatibility

Designed as an OEM-style replacement or standard tooling option for CNC milling applications requiring a 0.125-inch shank diameter collet or tool holder with a 5/64-inch cutting diameter end mill.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the collet or tool holder to the recommended engagement depth and verify runout before beginning a cut. Do not exceed the rated length of cut or apply side loads that exceed the tool geometry specifications.
