Frequently Asked Questions

What is the OSG Thread Mill 1664700509 used for?

The OSG Thread Mill 1664700509 is designed for threading aluminum and non-ferrous materials. Its helical flute and DLC-IGUSS coating reduce built-up edge, making it ideal for high-speed CNC machining of 1/4"-20 UNC threads in automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG Thread Mill 1664700509?

This OSG thread mill has a 1/4"-20 UNC thread size, 2 flutes, helical flute geometry, and DLC-IGUSS coated carbide. It features coolant-through capability for improved chip evacuation and tool life. The manufacturer part number is 1664700509, and it is designed specifically for aluminum and non-ferrous materials.

Where to buy the OSG Thread Mill 1664700509 worldwide?

3G Electric supplies the OSG Thread Mill 1664700509 worldwide. As a global industrial equipment distributor since 1990, we handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we source and deliver this thread mill to any country.

How to select the correct OSG thread mill for aluminum?

For aluminum threading, choose a thread mill with a DLC or DLC-IGUSS coating to prevent material adhesion. The OSG 1664700509 with helical flutes and coolant-through is optimized for aluminum. Match the thread size (e.g., 1/4"-20 UNC) and ensure your CNC machine supports helical interpolation for thread milling.
