Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is used for through-hole threading in production machining. Its spiral-point design pushes chips ahead, reducing chip clogging and enabling faster tapping cycles in steel, aluminum, and cast iron.

What are the specifications of the OSG 1/4"-28 UNF spiral point tap?

This OSG tap has a 1/4"-28 UNF thread, H3 / 2B-3B tolerance, 2-flute design, and bottoming chamfer. It is a general-purpose spiral-point tap for through-hole applications, MPN 1230501.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps worldwide, handling full logistics and customs clearance. We source genuine OSG cutting tools like the 1/4"-28 UNF spiral point tap and deliver to industrial buyers globally.

How to select the right OSG tap for a threading job?

Select an OSG tap based on thread size (e.g., 1/4"-28 UNF), hole type (through vs. blind), material, and tolerance class. Spiral point taps suit through holes; spiral flute taps suit blind holes. Consult OSG's application guide for optimal results.
