Frequently Asked Questions

What is the OSG Spiral Flute Tap 0138201 used for?

The OSG Spiral Flute Tap 0138201 is designed for threading blind holes in steel and stainless steel. Its spiral flute design efficiently evacuates chips upward, preventing clogging and ensuring clean threads. It is commonly used in automotive, aerospace, and general manufacturing applications requiring precise internal threads.

What are the specifications of the OSG Spiral Flute Tap 0138201?

This OSG tap has a thread size of 3/8"-24 UNF, with a H4 / 2B-3B tolerance class. It features 3 flutes and a bottoming chamfer, making it suitable for threading to the bottom of blind holes. The manufacturer part number is 0138201, and it is optimized for steel and stainless steel workpieces.

Where to buy the OSG Spiral Flute Tap 0138201 worldwide?

How to select the correct OSG tap for blind hole threading?

For blind hole threading in steel or stainless steel, choose a spiral flute tap with a bottoming chamfer, like the OSG 0138201. The spiral flute design pulls chips out of the hole, preventing breakage. Ensure the tap's thread class (e.g., H4 / 2B-3B) matches your required tolerance. Always use appropriate cutting fluid for material and speed.
