Frequently Asked Questions

What is the OSG spiral flute tap M8x1.25 used for?

The OSG spiral flute tap M8x1.25 is used for threading blind holes in metals, particularly in automotive and general manufacturing. Its spiral flute design evacuates chips upward, preventing clogging in deep holes. The TiN coating reduces friction and extends tool life. This tap is ideal for production environments requiring consistent, high-quality threads.

What are the specifications of the OSG spiral flute tap M8x1.25?

The OSG spiral flute tap has an M8x1.25 metric thread, 6H tolerance class, 3 flutes, and a bottoming chamfer. It is made of TiN coated high speed steel. The manufacturer part number is 2988405. This tap is designed for blind hole threading and provides good chip evacuation and wear resistance.
