Frequently Asked Questions

What is an OSG spiral-flute STI tap used for?

An OSG spiral-flute STI tap is used to cut internal threads in pre-drilled holes for screw thread inserts. It is designed for UNC threads, specifically 3/4"-10 UNC, and is commonly used in industrial maintenance, automotive, and aerospace applications where thread repair or reinforcement is required.

What are the specifications of the OSG STI tap 10801700?

The OSG STI tap model 10801700 has a 3/4"-10 UNC thread size, H5 tolerance for 2B-3B class fit, 4 flutes, and a bottoming chamfer. It features a spiral-flute design for efficient chip evacuation. The tap is made by OSG, a leading cutting tool manufacturer, and is suitable for threading in tough materials.

Where to buy OSG STI taps worldwide?

You can source OSG STI taps worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead times. 3G Electric supplies genuine OSG cutting tools for industrial applications.

How to select the correct OSG STI tap for a thread insert?

To select the correct OSG STI tap, match the tap thread size and pitch to the insert's internal thread. For a 3/4"-10 UNC insert, use an STI tap with the same designation. Ensure the tap has a bottoming chamfer for blind holes. OSG taps are precision-ground for accurate thread class fit, such as H5 for 2B-3B.
