Harvey Tool 41470 Single Profile Thread Mill 4 Flute Carbide

Product Description

The HARVEY TOOL 41470 is a solid carbide single profile thread mill designed for cutting both internal and external threads across a range of 12 to 32 TPI, covering 1/2-12 through 1/2-32 thread sizes. With a cutting diameter of 0.388 inches, a 0.5 inch shank diameter, and a 3 inch overall length, this tool is built for precision threading operations on CNC machining centers. The 4-flute geometry and bright uncoated finish make it suitable for a wide range of workpiece materials where a general-purpose threading solution is required. Machinists and toolroom operators rely on single profile thread mills for their ability to cut any thread pitch within range using a single tool and helical interpolation.

This thread mill is applicable in job shops, production machining, and maintenance environments where both internal and external thread forms are required in a single tool. The ability to mill threads from 12 to 32 TPI with one tool reduces tooling inventory and changeover time. It is well-suited for use in materials such as aluminum, steel, and non-ferrous alloys on 3-axis CNC mills or machining centers capable of helical interpolation. Installation and use require a compatible toolholder sized for a 0.5 inch shank.

Key Features

• Single profile design cuts any thread pitch from 12 to 32 TPI with one tool
• Machines both internal and external thread forms
• Solid carbide construction for rigidity and wear resistance
• 4-flute geometry for efficient chip evacuation
• Bright uncoated finish suitable for general-purpose threading applications
• Neck diameter of 0.25 inches with a 1.25 inch neck length for reach into bores

Compatibility

Designed for use in CNC machining centers capable of helical interpolation, accepting a 0.5 inch shank diameter toolholder. Compatible with thread sizes from 1/2-12 to 1/2-32 as specified by the tool geometry.

Installation Notes

This tool is installed and operated by machinists or CNC programmers on milling equipment capable of helical interpolation. Ensure the spindle and toolholder are properly cleaned and torqued before use. Program thread depth and lead per the specific thread standard being cut. Single profile thread mills require a correctly programmed helical toolpath and should not be used in a standard drilling or boring cycle.
