Selecting the right option
Spiral flute taps suit blind-hole tapping — the spiral ejects chips upward, preventing chip packing. HSS-Co5 cobalt grade suits stainless steel, titanium, and difficult materials at machine speeds. Use a titanium nitride (TiN) coated tap for improved surface finish and tool life in production runs.
