Frequently Asked Questions

What is an OSG straight flute tap used for?

An OSG straight flute tap is used for threading holes in aluminum and non-ferrous materials. The V coated powdered metal construction and coolant-through design reduce chip packing and heat, making it ideal for high-speed production tapping in automotive, aerospace, and general machining applications.

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

This OSG tap has a 5/8"-18 UNF thread, H3 / 2B-3B tolerance, 5 flutes, and a bottoming chamfer. It is made of V coated powdered metal and includes coolant-through capability. The manufacturer part number is 1005302408.

Where to buy OSG taps in worldwide?

How to select the right OSG tap for aluminum?

For aluminum, choose a tap with a polished flute and coating to reduce built-up edge. OSG's V coated powdered metal taps with coolant-through design are well-suited. Match thread size, pitch, and chamfer type (bottoming for blind holes) to your application. Confirm tolerance class (H3) meets your required fit.
