Frequently Asked Questions

What is OSG thread forming tap 1/4"-20 UNC used for?

This OSG thread forming tap creates internal threads in ductile materials like aluminum, steel, and stainless steel without cutting chips. It is ideal for high-speed production environments where chip evacuation is problematic, such as automotive and aerospace manufacturing.

What are the specifications of OSG thread forming tap 1/4"-20 UNC?

This OSG tap has a 1/4"-20 UNC thread size, H6 / 2B-3B tolerance, plug chamfer, and TiCN coated cobalt construction. The TiCN coating reduces friction and extends tool life in abrasive materials. Manufacturer part number is 1400127308.
