Harvey Tool 993930-C3 Thread Mill 8-32 to 8-36 Solid Carbide

Product Description

The HARVEY TOOL 993930-C3 is a single profile thread mill designed to cut internal and external threads in the 8-32 to 8-36 size range, covering 32 to 36 threads per inch (TPI). Built from solid carbide and coated with AlTiN for heat and wear resistance, this tool is suited for high-speed threading operations in ferrous and non-ferrous materials. The cutting diameter measures 0.12 inches with a 1/4 inch shank diameter and an overall length of 2.5 inches. Four flutes provide clean chip evacuation and stable cutting action. Machinists and CNC operators use this tool for precision threading in production and job shop environments.

This thread mill is used in CNC machining centers for both internal and external thread milling in a wide range of workpiece materials. Its single profile design allows one tool to handle multiple thread pitches within the 32 to 36 TPI range, reducing the need for multiple taps or dies. The 0.07 inch neck diameter and 0.75 inch neck length allow access to threads in blind holes and tight clearance conditions. Typical applications include threaded holes and fastener features in precision machined components across general manufacturing, aerospace, and defense work.

Key Features

• Single profile design covers 8-32 through 8-36 thread sizes in one tool
• Cuts both internal and external threads for versatile application
• Solid carbide construction for rigidity and long tool life
• AlTiN coating provides oxidation resistance and reduces friction at elevated temperatures
• Four-flute geometry supports efficient chip removal during continuous threading passes
• 0.07 inch neck diameter with 0.75 inch neck length enables access to confined and deep thread features

Compatibility

Designed for use in CNC machining centers capable of helical interpolation; compatible with standard 1/4 inch collet or end mill holders. Cuts threads in the 8-32 to 8-36 range on workpieces where standard tapping is not practical.

Installation Notes

Thread milling requires a CNC control with helical interpolation capability. Secure the tool in a properly sized collet or shrink-fit holder to minimize runout before cutting. Verify spindle speed and feed rate calculations for the specific workpiece material prior to threading. Always confirm tool projection and clearance in the holder before engaging the workpiece to avoid interference.
