Frequently Asked Questions

What is OSG spiral point tap #2-56 UNC used for?

OSG spiral point taps are designed for through-hole threading in production environments. The #2-56 UNC size is common in precision machining, automotive, and aerospace applications where fast, chip-free threading is required.

What are the specifications of OSG tap 2805608?

The OSG 2805608 is a #2-56 UNC spiral point tap with H2 / 2B-3B tolerance, 2 flutes, and a plug chamfer. It is a general-purpose tap for through-hole threading in ferrous and non-ferrous materials.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps like the 2805608 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this and other OSG cutting tools.

How to select the right tap for #2-56 UNC threads?

For #2-56 UNC threads, choose a spiral point tap for through holes or a spiral flute tap for blind holes. Verify the thread class (e.g., 2B) and chamfer type (plug, bottoming, or taper) match your application. OSG taps offer consistent geometry for reliable results.
