Carmex S0250C5932UN Thread Mill 10-32 3 Flute Solid Carbide

Product Description

The CARMEX S0250C5932UN is a helical flute thread mill designed for cutting internal 10-32 UNF threads in precision machining applications. Built from solid carbide grade MT7 and coated with TiAlN for heat and wear resistance, this mini thread mill handles right-hand and left-hand flute direction cutting in a single tool. The 0.146-inch cutting diameter and 3-flute geometry allow smooth, controlled thread milling in confined bores. With an overall length of 2.5 inches and a 0.25-inch shank diameter, the tool fits standard collet and end mill holders used on CNC machining centers.

This thread mill is suited for job shops, aerospace, automotive, and general manufacturing environments where 10-32 UNF internal threads are required in ferrous and non-ferrous materials. The mini thread mill classification makes it appropriate for small-bore applications where standard-size thread mills cannot reach or fit. A licensed machinist or CNC programmer typically specifies and runs this tooling on vertical or horizontal machining centers with helical interpolation capability.

Key Features

• 10-32 UNF internal thread profile, 32 teeth per inch
• Solid carbide MT7 grade construction for rigidity and long tool life
• TiAlN coating improves heat resistance and surface hardness for extended runs
• 3-flute helical design reduces cutting forces and improves chip evacuation
• Left-hand and right-hand flute direction compatibility in one tool
• Mini thread mill classification suited for small-bore internal threading

Compatibility

Designed for use in CNC machining centers capable of helical interpolation for cutting 10-32 UNF internal threads. Compatible with standard 0.25-inch shank collet chucks and end mill holders.

Installation Notes

This tooling is installed and operated by qualified CNC machinists or tooling engineers. Ensure the tool holder is clean and properly torqued to manufacturer specifications before running. Program helical interpolation at the correct pitch for 10-32 UNF before engaging the cut. Coolant-through is not supported on this tool, so verify adequate external coolant or air blast is directed at the cutting zone during operation.
