Frequently Asked Questions

What is an OSG spiral flute tap used for?

An OSG spiral flute tap is used for threading blind holes in steel and stainless steel. Its spiral flute design lifts chips upward, preventing clogging and ensuring clean threads. The modified bottoming chamfer allows threading close to the hole bottom, making it ideal for automotive, aerospace, and general manufacturing applications.

What are the specifications of the OSG spiral flute tap M4x0.7?

This OSG tap has a metric M4x0.7 thread, a D4 / 4H-6H tolerance class, 3 flutes, and a modified bottoming chamfer. It is designed for threading blind holes in steel and stainless steel. The manufacturer part number is 1755405.

How to select the right OSG tap for steel?

For steel, choose an OSG spiral flute tap for blind holes or a spiral point tap for through holes. Match the thread size (e.g., M4x0.7) and tolerance class (e.g., D4 / 4H-6H) to your application. Use cutting fluid and proper speed to extend tool life. 3G Electric can help you select the correct OSG tap.
