OSG Thread Mill: Helical Flute, M4x0.7 Metric, 2 Flute

An OSG helical-flute thread mill is used for high-speed threading in aluminum and non-ferrous materials. Its DLC-IGUSS coated carbide design reduces built-up edge and extends tool life, making it ideal for automotive, aerospace, and general machining applications where precision M4x0.7 metric threads are required.

The OSG thread mill model 8331221 features a helical flute design, M4x0.7 metric thread size, 2 flutes, and DLC-IGUSS coated carbide construction. It is manufactured by OSG and is specifically designed for threading aluminum and similar materials, providing smooth chip evacuation and consistent thread quality.

3G Electric supplies OSG thread mills worldwide, handling full logistics and customs clearance for international orders. As a global industrial sourcing partner, we provide genuine OSG cutting tools like the 8331221 helical-flute thread mill, ensuring you receive the correct specifications for your machining operations.

To select the right OSG thread mill for aluminum, match the thread size (e.g., M4x0.7), flute count, and coating to your material. For aluminum, a DLC-IGUSS coated carbide tool with helical flutes reduces friction and chip welding. Consult OSG's technical data for recommended speeds and feeds to optimize tool life and thread quality.
