Harvey Tool 41455 Single Profile Thread Mill 5/16-18 to 5/16-48

Product Description

The HARVEY TOOL 41455 is a solid carbide single profile thread mill designed to cut both internal and external threads across a wide range from 5/16-18 to 5/16-48, covering 18 to 48 TPI in a single tool. With a 0.24-inch cutting diameter, a 1/4-inch shank, and a 2.5-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 well suited for threading a variety of materials where coating buildup is not a concern. Machinists and tooling professionals rely on single profile thread mills for flexibility across thread pitches without changing tools.

This thread mill is used in production and job shop environments where a single tool needs to cover multiple thread specifications. It handles both internal and external thread forms, making it appropriate for threaded bores and external threaded features on the same workpiece. The 0.16-inch neck diameter and 0.75-inch neck length provide clearance for threading in confined or deep-pocket applications. It is suited for use in CNC machining centers running standard helical interpolation routines.

Key Features

• Covers 18 to 48 TPI in a single tool, reducing changeover for multi-pitch jobs
• Machines both internal and external thread forms
• Solid carbide construction for rigidity and wear resistance
• 4-flute design for efficient chip evacuation during threading
• Bright uncoated finish suitable for a range of base materials
• 0.16-inch neck diameter with 0.75-inch neck length for clearance in tight applications

Compatibility

Designed for use in CNC machining centers with helical interpolation capability; compatible with 1/4-inch toolholders and collet chucks. Cuts thread sizes from 5/16-18 through 5/16-48 on both internal and external features.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with CNC thread milling routines. Secure the shank in a properly sized collet or toolholder rated for the spindle speed and feed rate required. Verify helical interpolation parameters in the CNC program before cutting to avoid tool deflection or thread form errors. Inspect the cutting edges before each use; solid carbide tools are brittle and should not be dropped or subjected to side impact loads.
