Frequently Asked Questions

What is a CLEVELAND spiral flute tap used for?

What are the specifications of the CLEVELAND M18x2.5 spiral flute tap?

This CLEVELAND tap has M18x2.5 metric thread, 6H tolerance, 4 flutes, semi-bottoming chamfer, and TiAlN coated cobalt construction. The TiAlN coating provides heat resistance and extends tool life in hard materials. Manufacturer part number is C89251.

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 this CLEVELAND M18x2.5. The 4-flute design balances strength and chip clearance. Ensure the tap's thread class (6H) matches your hole tolerance. TiAlN coating helps when tapping abrasive materials.
