Harvey Tool 882122 Thread Mill M2.5 X 0.45 2 Flute Carbide

Product Description

The HARVEY TOOL 882122 is a single profile thread mill designed to cut M2.5 x 0.45 threads in both internal and external configurations. Built from solid carbide with a bright, uncoated finish, this tool offers the rigidity and wear resistance required for precision threading in a range of workpiece materials. It features 2 flutes and a cutting diameter of 1.9 inches, with an overall length of 1.4961 inches. The neck diameter measures 1.14 inches and the neck length is 0.2283 inches. Machinists and CNC operators use single profile thread mills like this one when threading small-diameter features where standard taps cannot reliably enter or exit.

This thread mill is suited for CNC machining centers performing small-format threading operations. The M2.5 x 0.45 profile covers both internal bores and external forms in a single tool, reducing the number of tools required on the machine. The 3.00 mm shank diameter fits standard ER collets and small-bore tool holders commonly found on vertical machining centers and multi-axis equipment. This tool is appropriate for prototype work, short-run production, and precision component manufacturing where thread quality and repeatability are critical.

Key Features

• Cuts M2.5 x 0.45 threads in both internal and external applications with a single tool
• Solid carbide construction provides rigidity and dimensional stability at cutting speed
• 2-flute geometry suited for small-diameter threading with chip clearance in confined bores
• Bright, uncoated finish compatible with a wide range of cutting fluids and workpiece materials
• 3.00 mm shank fits standard ER collet systems and small-bore tool holders
• Overall length of 1.4961 inches keeps the tool compact for tight-clearance setups

Compatibility

Designed for use in CNC machining centers with tool holders accepting a 3.00 mm shank diameter. Suitable for threading M2.5 x 0.45 features in materials compatible with uncoated solid carbide tooling.

Installation Notes

Installation and operation of this thread mill should be performed by a qualified CNC machinist or tooling technician. Ensure the spindle is fully stopped and the machine is in a safe state before loading the tool into the holder. Verify runout at the collet before cutting, as excessive runout at small diameters accelerates tool wear and degrades thread quality. Program helical interpolation per the tool manufacturer's recommended parameters and confirm thread form with a go/no-go gauge after the first part.
