Frequently Asked Questions

What is an OSG spiral point tap used for?

An OSG spiral point tap is designed for through-hole threading in production environments. Its spiral point pushes chips ahead, preventing clogging. This 3/8"-24 UNF tap with TiCN coating handles tough materials like alloy steel, delivering clean threads in automotive and general machining applications.

What are the specifications of the OSG 2856808 tap?

The OSG 2856808 is a 3/8"-24 UNF spiral point tap with H11 tolerance, 3 flutes, plug chamfer, and TiCN coated vanadium high speed steel. It is an oversized tap for controlled thread depth. These specs ensure precision in demanding threading operations.

Where to buy OSG taps in worldwide?

How to select the right OSG tap for a job?

Select an OSG tap by matching thread size (e.g., 3/8"-24 UNF), material (vanadium HSS for steel), coating (TiCN for wear resistance), and chamfer type (plug for through-holes). Oversized taps like H11 allow for controlled thread fit. Consult OSG's technical data for optimal speeds and feeds.
