Frequently Asked Questions

What is the OSG spiral flute tap used for?

The OSG spiral flute tap is used for threading blind holes in materials such as steel, stainless steel, and aluminum. Its spiral flute design lifts chips upward, preventing clogging and ensuring clean threads. It is ideal for automotive, aerospace, and general manufacturing applications requiring precise internal threads.

What are the specifications of the OSG spiral flute tap?

The OSG spiral flute tap has a thread size of 1"-12 UNF, a 2B class of fit, 4 flutes, and a modified bottoming chamfer. The manufacturer part number is 2239601. It is designed for general purpose threading in blind holes, providing efficient chip evacuation and consistent thread quality.

Where to buy the OSG spiral flute tap worldwide?

You can source the OSG spiral flute tap worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time; we provide reliable sourcing and supply for this OSG tap.

How to select the correct OSG spiral flute tap for blind holes?

To select the correct OSG spiral flute tap for blind holes, match the thread size (e.g., 1"-12 UNF) and class of fit (2B) to your application. Ensure the tap has a modified bottoming chamfer for threading close to the hole bottom. OSG taps are designed for efficient chip removal in blind holes, reducing breakage risk.
