Straight Flute Taps

Straight flute taps are the most commonly used type of thread tap. The Straight taps are made of high-hardness materials such as high-speed steel and cemented carbide. Straight flute taps can have 2, 4, and 6 teeth in the cutting cone. The cutting speed is slower. The long shank straight flute tap is used for through holes, and the short shank Straight taps are used for blind holes.

Advantage of straight flute taps:

  • Straight flute taps are easy to tapping metal threads but have slightly lower precision and larger output.
  • Straight flute taps have been widely used in the machining industry because of their convenient processing, low price, and robust versatility.

Straight flute taps Application:

  •  Straight flute thread taps are widely used for tapping internal threads of ordinary lathes, drilling machines, and tapping machines.
  •    The straight flute tap has the best versatility and the most strong rigidity. Therefore, straight flute taps are generally preferred when tapping metal threads with higher hardness (such as threading hardened steel above 40HRC) and powder particles (such as threading cast iron and cast aluminum).
  •   Regardless of through-hole or blind hole, metal and non-metal, standard steel, and various non-ferrous metals can be processed.
