Frequently Asked Questions

What is a CLEVELAND spiral flute tap used for?

A CLEVELAND spiral flute tap is used for threading blind holes in metal, as its spiral design pushes chips upward and out of the hole. This makes it ideal for production tapping in machining, automotive, and general manufacturing applications where chip evacuation is critical.

What are the specifications of the CLEVELAND C98133 tap?

The CLEVELAND C98133 is a 1"-12 UNF spiral flute tap with a 2B class fit, 4 flutes, and a semi-bottoming chamfer. It is made from black oxide cobalt for heat resistance and durability. This tap is designed for threading blind holes in ferrous and non-ferrous materials.

How to select the right spiral flute tap for blind holes?

For blind holes, choose a spiral flute tap with a semi-bottoming chamfer, like the CLEVELAND C98133, to thread close to the hole bottom. Ensure the tap size matches the thread specification (e.g., 1"-12 UNF) and material compatibility—cobalt for harder metals. Always use proper cutting fluid.
