Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is used for through-hole threading in metalworking. Its spiral-point design pushes chips forward, preventing clogging and enabling faster, cleaner threading in production environments across machining, automotive, and general manufacturing.

What are the specifications of the OSG spiral point tap M4x0.7?

This OSG tap has a metric M4x0.7 thread, D4 / 4H-6H tolerance, 2 flutes, plug chamfer, and black oxide high-speed steel construction. The manufacturer part number is 1980401. It is designed for general-purpose through-hole threading in steel and non-ferrous materials.

How to select the correct OSG tap for a job?

Select an OSG tap based on thread size (M4x0.7), hole type (through vs. blind), material (steel, aluminum), and tolerance class (D4 / 4H-6H). For through holes, a spiral point tap like this one pushes chips forward. Always match tap coating and geometry to workpiece hardness.
