Frequently Asked Questions

What is the OSG Extension Tap M6x0.75 used for?

The OSG Extension Tap M6x0.75 is used for threading blind or deep holes in multiple materials, including steel, stainless steel, and aluminum. Its 3-flute spiral-flute design and modified bottoming chamfer help evacuate chips upward, making it ideal for through-hole and blind-hole applications where chip clearance is critical.

What are the specifications of the OSG Extension Tap M6x0.75?

The OSG Extension Tap has a metric M6x0.75 thread size, a D4 / 4H-6H tolerance class, and a modified bottoming chamfer. It features 3 spiral flutes for efficient chip evacuation and is designed for threading multiple materials. The manufacturer part number is 1652002508.

Where to buy the OSG Extension Tap M6x0.75 worldwide?

How to select the correct OSG extension tap for a job?

To select the correct OSG extension tap, match the thread size (e.g., M6x0.75) and tolerance class (e.g., D4 / 4H-6H) to your hole requirements. Consider material type—OSG taps are designed for multiple materials. For blind holes, choose a modified bottoming chamfer; for through holes, a plug chamfer may suffice. Always verify the flute count and coating for your application.
