Harvey Tool 826519 Thread Mill M2 X 0.40 2 Flutes Carbide

Product Description

The HARVEY TOOL 826519 is a solid carbide single profile thread mill designed to cut M2 x 0.40 metric threads in both internal and external applications. With a 1.5-inch cutting diameter and a 2-flute geometry, this tool produces precise thread forms in a single helical pass. It is suited for use on CNC machining centers capable of helical interpolation. The bright, uncoated finish makes it appropriate for a range of workpiece materials where coating-induced dimensional buildup is a concern. At 1.4961 inches overall length, it fits compact tooling setups without sacrificing reach.

This thread mill is used in precision machining environments where a single tool must handle both internal and external thread profiles on small-diameter features. The M2 x 0.40 pitch range is common in instrument manufacturing, medical device production, electronics enclosures, and other applications requiring fine metric fastener threads. It is installed by CNC machinists and toolroom technicians working to close tolerances on small part features.

Key Features

• Cuts M2 x 0.40 metric thread profile in both internal and external configurations
• 2-flute solid carbide construction for rigidity and wear resistance on small-diameter work
• 1.5-inch cutting diameter with a 0.9-inch neck diameter for clearance in confined bores
• Neck length of 0.2756 inches provides reach without excessive overhang
• Bright, uncoated finish suitable for materials sensitive to coated-tool dimensional variation
• Single profile geometry allows thread size adjustment through CNC cutter compensation

Compatibility

Designed as an OEM-style single profile thread mill for CNC machining centers capable of helical interpolation, compatible with M2 x 0.40 metric thread applications requiring internal or external thread forms.

Installation Notes

This tool is installed and operated by CNC machinists using helical interpolation cycles on 3-axis or higher machining centers. Ensure the tool is properly seated and torqued in the appropriate collet or toolholder before running. Verify CNC program cutter compensation values match the actual cutting diameter before cutting production parts. Inspect the cutting edges for chipping before each use, as carbide tooling is brittle and sensitive to improper handling.
