Accupro 930-01032 Thread Mill 10-32 Internal 3 Flute Carbide

Product Description

The ACCUPRO 930-01032 is a helical flute thread mill designed for cutting internal 10-32 UNF threads in a single helical pass. Built from micrograin solid carbide, it delivers the rigidity and edge retention needed for consistent thread quality in hardened and abrasive materials. The tool features a 0.1200 inch cutting diameter, a 1/2 inch length of cut, and a TiAlN coating that extends tool life under high-heat cutting conditions. With 3 flutes and 32 teeth per inch, it produces clean thread forms with efficient chip evacuation. Machinists and toolroom professionals use this mill on CNC machining centers where interpolation capability is available.

This thread mill is suited for internal threading operations on CNC mills and machining centers in both production and prototype environments. Its 1/4 inch shank diameter makes it compatible with standard collet chucks and end mill holders commonly found in job shops and manufacturing facilities. The UNF thread standard and 10-32 size are common in instrument panels, electronics enclosures, and light mechanical assemblies where fine-pitch threads are required in steel, aluminum, and similar machinable alloys.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• TiAlN coating reduces heat buildup and extends tool life in ferrous materials
• 3-flute helical design promotes efficient chip removal during thread milling
• 0.1200 inch cutting diameter sized for 10-32 UNF internal threads
• 1/2 inch length of cut accommodates standard thread depth requirements for this size
• No coolant-through design — compatible with flood or mist coolant delivery from the outside

Compatibility

Designed for use in CNC machining centers capable of helical interpolation; accepts standard 1/4 inch collet chucks and end mill holders. Cuts 10-32 UNF internal threads per the Unified National Fine thread standard.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with CNC thread milling cycles and helical interpolation programming. Ensure the spindle is fully stopped and the machine is in a safe state before installing or removing the tool from the holder. Verify runout at the collet before threading operations, as excessive runout will degrade thread quality and reduce tool life. Follow the machine tool manufacturer guidelines for feed rate and spindle speed when programming the helical interpolation path.
