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 evacuates chips upward, preventing clogging and enabling clean threads in deep or blind-hole applications. This M8x1.25 metric tap with a modified bottoming chamfer is ideal for threading close to the bottom of a hole.

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

This OSG tap has a metric thread size of M8x1.25, a D5 / 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 1756308.

How to select the right spiral flute tap for steel?

Select a spiral flute tap based on thread size, pitch, and material. For steel and stainless steel blind holes, choose a tap with a modified bottoming chamfer to thread near the hole bottom. Ensure the tolerance class (e.g., D5 / 4H-6H) matches your required thread fit. OSG taps are a reliable choice for these applications.
