Where chips remain in a straight-flute tap
The flute holds the chips until the tap is reversed out
The straight flute runs parallel to the tap axis. There is no helix to carry chips upward. The chamfer cutting edges are not ground at an angle, so they do not push chips downward. Short chips break into fragments and remain in the flute beside the cutting edges that produced them. They leave the hole only when the tap is reversed out. The UNF No 8-36 tap has a reduced shank in accordance with DIN 374: diameter 2.8 mm, square 2.1 mm.

No 8-36 UNF American fine-thread machine tap
Professional No 8-36 UNF fine-thread machine tap for cutting American Unified fine threads. Thread type: UNF No 8-36 threads per inch. The tap has an extended shank according to DIN 374. Triangular thread profile with a 60° angle. Tolerance class of the threads produced: 2B. Form C chamfer – for through holes and blind holes of various depths in materials producing short chips. We offer Unified machine taps made from modern high-speed steel (HSS). This steel makes the taps highly productive and allows machining time to be reduced. This enables more efficient use of existing workstations and reduces production costs. No 8-36 UNF machine taps made from HSSE steel also withstand demanding operating conditions, particularly the very high temperatures (up to 600°) generated during high-speed cutting. They are suitable for machining components made from unalloyed steel, metals, copper, bronze, aluminum, brass, and plastics.
