Product Description
Metric coarse high speed steel spiral flute taps for creating internal standard pitch metric threads, especially in blind hole tapping applications.
These metric HSS spiral flute taps are designed with helical flutes that help pull chips and swarf back out of the hole towards the shank, opposite to the tapping direction. This makes them especially useful for blind holes, where chip evacuation is important for cleaner thread cutting and improved tap life compared with standard hand taps.
