Frequently Asked Questions

What is the OSG spiral flute tap 2942701 used for?

The OSG spiral flute tap 2942701 is used for threading blind holes in materials like steel and aluminum. Its spiral flute design lifts chips upward, preventing clogging, making it ideal for automotive and general manufacturing applications where clean threads are critical.

What are the specifications of the OSG spiral flute tap 2942701?

The OSG spiral flute tap 2942701 has a 1/2"-13 UNC thread size, H11 / 2B tolerance, 3 flutes, and a modified bottoming chamfer. It is an oversized tap designed for threading close to the bottom of blind holes. The manufacturer part number is 2942701.

Where to buy the OSG spiral flute tap 2942701 worldwide?

You can source the OSG spiral flute tap 2942701 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide locations, ensuring you receive the correct tap for your threading needs.

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., 1/2"-13 UNC) and tolerance (e.g., H11 / 2B) to your application. Choose a modified bottoming chamfer for threading near the hole bottom. OSG taps are designed for chip evacuation in blind-hole threading.
