Frequently Asked Questions

What is an OSG spiral flute tap used for?

An OSG spiral flute tap is used for threading blind holes in materials such as steel, stainless steel, and aluminum. The spiral flute design lifts chips upward, preventing clogging and ensuring clean threads. This M7x1 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 M7x1?

This OSG tap has a metric thread size of M7x1, a D5 / 4H-6H tolerance class, 3 flutes, and a modified bottoming chamfer. The 4H-6H tolerance ensures precise thread fit for general-purpose applications. The manufacturer part number is 2991101.

Where to buy OSG taps in worldwide?
