Frequently Asked Questions

What is the OSG spiral point tap 5/8"-18 UNF used for?

This OSG spiral point tap is designed for threading through-holes in production environments. Its TiN coating reduces friction and extends tool life in ferrous and non-ferrous materials. The plug chamfer and 3-flute design efficiently evacuate chips forward, making it ideal for high-speed tapping operations.

What are the specifications of the OSG spiral point tap MPN 1233405?

The OSG spiral point tap MPN 1233405 has a thread size of 5/8"-18 UNF, with a tolerance class of H3 / 2B-3B. It features 3 flutes, a plug chamfer, and a TiN coated high-speed steel construction. This general-purpose tap is suitable for threading both 2B and 3B class holes.

How to select the correct OSG tap for UNF threads?

To select the correct OSG tap for UNF threads, match the thread size (e.g., 5/8"-18 UNF) and tolerance class (H3 / 2B-3B) to your application. Consider material, hole type (through or blind), and coating. For through-holes, a spiral point tap with plug chamfer is recommended. Always verify the manufacturer part number, such as 1233405.
