Frequently Asked Questions

What is the OSG spiral point tap 1241600 used for?

This OSG spiral point tap is designed for through-hole threading in production environments. Its 3-flute design pushes chips forward, reducing clogging and tap breakage in steel, aluminum, and cast iron. It is ideal for automotive, aerospace, and general machining applications requiring consistent UNC threads.

What are the specifications of the OSG 3/8-16 UNC spiral point tap?

The OSG spiral point tap (MPN 1241600) has a 3/8-16 UNC thread, H5 tolerance for 2B-3B class fit, 3 flutes, and a plug chamfer. It is made from high-speed steel. This combination provides precise thread forming and chip evacuation in through-hole applications across multiple materials.

Where to buy OSG taps in worldwide?

3G Electric supplies OSG taps like the 1241600 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial sourcing partner, we provide genuine OSG cutting tools with technical support for thread sizing and material compatibility.

How to select the right OSG tap for UNC threads?

Select an OSG tap based on thread size (e.g., 3/8-16 UNC), hole type (through vs. blind), material hardness, and required thread class (2B-3B). Spiral point taps suit through holes; spiral flute taps suit blind holes. Consult OSG's technical data for H5 tolerance and chamfer type to match your application.
