Frequently Asked Questions

What is the OSG spiral flute tap M12x1.25 used for?

The OSG spiral flute tap M12x1.25 is designed for threading blind holes in steel and stainless steel. Its spiral flute design lifts chips upward, preventing clogging in deep or blind 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 1745801?

The OSG spiral flute tap 1745801 has a metric M12x1.25 thread size, D5 / 4H-6H tolerance class, 3 flutes, and a modified bottoming chamfer. It is designed for steel and stainless steel. The D5 / 4H-6H designation indicates a ground thread tap for precise, high-accuracy threading in production environments.

How to select the right OSG tap for stainless steel?

For stainless steel, choose an OSG spiral flute tap with a modified bottoming chamfer, like the M12x1.25 D5 / 4H-6H model. The spiral flute design evacuates chips effectively in blind holes. Ensure the tap's tolerance class matches your thread fit requirement. Use appropriate cutting fluid and speed to extend tool life and achieve clean threads.
