Frequently Asked Questions

What is the OSG 1400151808 thread forming tap used for?

The OSG 1400151808 is a general-purpose thread-forming tap used to create internal threads in ductile materials like aluminum, brass, and low-carbon steel. It is ideal for applications requiring strong, chip-free threads in automotive, aerospace, and general manufacturing. The TiCN coating extends tool life in abrasive materials.

What are the specifications of the OSG 5/8"-18 UNF thread forming tap?

This OSG tap has a 5/8"-18 UNF thread size, H5 tolerance for 2B-3B fit classes, and a modified bottoming chamfer. It is made from cobalt high-speed steel with a TiCN coating. The manufacturer part number is 1400151808. It is designed for thread forming, not cutting, to produce strong threads without chips.

Where to buy the OSG 1400151808 thread forming tap worldwide?

You can source the OSG 1400151808 thread forming tap through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time. We supply genuine OSG tooling for manufacturing operations.

How to select the correct OSG thread forming tap for my application?

Select the OSG thread forming tap based on thread size (5/8"-18 UNF), material hardness, and hole depth. For blind holes, use a modified bottoming chamfer as on this tap. Ensure the tap drill size matches the 2B-3B fit class. The TiCN coating suits abrasive materials. Consult OSG's technical data for optimal speeds and lubrication.
