Spiral flute taps lift swarf back up and out of the hole as they cut, which is exactly what a blind hole needs. The chips have nowhere else to go, and packed swarf is the single biggest cause of broken taps.

Available in HSS-E across metric and imperial thread forms, with carbide options for cast iron and higher-volume work. If you are tapping through holes instead, a spiral point will run faster.
