1 Screw tip tap: The cutting part is ground with a chute to form a negative edge angle (see tool). The chips are discharged forward during cutting and are suitable for tapping through holes.
2 Spiral groove tap: The chip flute is spiral. When machining the blind hole right-hand thread, the tap should make the right spiral chip flute, so that the chip is discharged forward without scratching the thread.
3 No-slot extrusion tap: The plastic deformation of the metal is formed by the plastic deformation of the extruded hole wall, mainly used for processing plastic materials such as aluminum alloy and copper, and also processing low carbon steel and stainless steel. In order to reduce the friction and reduce the pressing force, the taper section is made into a polygon. The extrusion tap has high strength and is especially suitable for processing small-sized screw holes with a diameter of 6 mm or less.
4 Jumping taps: Grinding a tooth along the spiral direction of the cutter, thus increasing the chip thickness, facilitating chip breaking and chip removal, and processing workpieces such as stainless steel.
5 Content chip tap: The chip is discharged from the inner hole of the tap for processing large-size screw holes.
6 automatic shrink tap: After the tapping is completed, the tap teeth can automatically shrink inward to quickly exit.
7 broaching tap: It is a broach with a tooth on the spiral line, which is often used to machine trapezoidal and square thread.
8 carbide taps: mainly used for processing cast iron and non-ferrous metals, high cutting efficiency and tool life.
