Frequently Asked Questions

What is the OSG spiral flute tap M12x1.75 used for?

The OSG spiral flute tap M12x1.75 is designed for threading blind holes in steel and stainless steel. Its spiral flute design lifts chips upward, preventing clogging in deep holes. 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 MPN 1756905?

The OSG spiral flute tap MPN 1756905 has a metric M12x1.75 thread size, a D6 / 4H-6H tolerance class, 3 flutes, and a modified bottoming chamfer. It is designed for threading steel and stainless steel. The D6 / 4H-6H designation indicates a ground thread tap for precise, high-accuracy internal threads.
