Frequently Asked Questions

What is an OSG spiral flute tap used for?

This OSG tap has a metric thread size of M33x1.5, a D8 / 4H-6H tolerance class, 4 flutes, and a modified bottoming chamfer. It is designed for threading blind holes in steel and stainless steel. The manufacturer part number is 1650007808.
