How a spiral flute tap evacuates chips from a blind hole
The 40° flute works like a screw conveyor
The flutes of this tap spiral to the right at an angle of 40° to the axis. The tap rotates clockwise and advances into the hole. The chip cut by the chamfer enters the flute, and the helix carries it upward like the auger in a meat grinder. The bottom of the hole stays clean, and the cutting edges do not encounter packed chips. The UNF 9/16-18 tap has a reduced shank in accordance with DIN 374: diameter 11 mm, square 9 mm.

9/16-18 UNF American spiral-flute machine tap
Professional 9/16-18 UNF machine tap with a reduced shank, compliant with DIN 374. Suitable for machine cutting American Unified threads. These are UNF fine threads, 9/16 inch in diameter, with 18 threads per inch. The threads have a triangular profile with a 60° angle. Chamfer type C – for blind and through holes with a long thread runout. The tolerance class of the finished threads is 2B. The offered 9/16-18 UNF machine taps Unified taps are manufactured to the highest precision from special cobalt high-speed steel HSSE (High Speed Steel).
This specialized tool steel offers high abrasion resistance even at the elevated temperatures (up to 600°C) generated during high-speed machining. As a result, these taps rarely suffer mechanical damage such as breakage, cracking, edge chipping, spalling or even dulling. They are suitable for machining unalloyed steels, metals, nonferrous metals, metal alloys and other materials.
