How to select the right spiral flute tap for blind holes?
For blind holes, choose a spiral flute tap with a bottoming chamfer to thread close to the hole bottom. Match the tap's thread size, pitch, and tolerance class (e.g., H5 / 2B) to your application. Cobalt steel with black oxide coating improves tool life in ferrous materials. Always use proper cutting fluid and speed.
