Harvey Tool 72090 Square End Mill 3/32 in 2 Flute Carbide

Product Description

The HARVEY TOOL 72090 is a solid carbide square end mill designed for precision milling in demanding machining environments. With a 3/32-inch (0.090 inch) cutting diameter and a 17/64-inch (0.270 inch) length of cut, this tool is built for slotting, profiling, and peripheral milling in tight geometries. The 1/8-inch shank diameter keeps it compatible with standard collets and tool holders used on CNC mills and manual milling machines. At 1-1/2 inches overall length and weighing approximately 0.01 pounds, it is suited for work in confined spaces or on small workpieces. Machinists and toolroom operators working in production or prototype environments are the primary users.

This end mill is used in applications requiring accurate square-shoulder cuts and clean floor finishes. The 30-degree helix angle and two-flute geometry provide efficient chip evacuation, making it appropriate for milling aluminum, plastics, and softer non-ferrous materials as well as light cuts in steels. The centercutting design allows plunge entry, giving operators flexibility in toolpath programming. The uncoated finish makes it straightforward to inspect for wear and suitable for applications where coating residue could be a concern.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision milling
• 3/32-inch cutting diameter for fine-detail and small-feature work
• 17/64-inch length of cut suits shallow-to-medium depth slotting and profiling
• 30-degree helix angle promotes efficient chip flow and smooth cutting action
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute configuration - standard orientation for CNC and manual mills
• Uncoated surface finish for easy wear inspection and broad material compatibility

Compatibility

Designed for use in standard 1/8-inch collets and compatible tool holders on CNC machining centers and manual milling machines requiring a square end mill with a 3/32-inch cutting diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the 1/8-inch shank in a properly sized collet or end mill holder, torquing the collet nut per the tool holder manufacturer specification. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Verify runout with a dial indicator after seating to protect both the tool and the workpiece from premature wear or dimensional error.
