High Speed Steel thread tap for Wire Thread Inserts

Thread tap is an essential tool in the installation of wire threaded inserts

To tap the AVIC-Flight Plus tapped hole, system dependent original AVIC-Flight taps must be used. We have suitable manual and machine taps on offer. The overview provides all necessary information. The standard taps from the AVIC-Flight system comply with almost all practical requirements. For critical chip removal requirements, such as materials difficult to machine (stainless and heat-resisting steels, different steel and titanium alloys), we offer special machine taps. The overview provides the machine taps for the respective materials including recommended guide values for cutting speed.

■Straight groove 

Cutting angle of 10 °, rotary cutting head, for through hole, At the initial stage of tapping, it is necessary to screw in 4 times the pitch, and a deep hole shall be drilled in advance for the blind hole. 

For materials with strength less than or exceeding 700 n / mm2. 

For tapping through holes. 

■Spiral groove 

Machine tap, 45 ˚ Spiral groove, right rotation, cutting angle 15 ˚， 

For blind holes, it is necessary to screw in twice the pitch at the initial stage of tapping. 

For materials with strength less than 700 n / mm2. 

It can be used to tap blind holes.

■Extrusion tap 

Suitable for processing non-ferrous metals with high toughness, especially copper and aluminum alloy castings; 

Realize chip free machining, strengthen the strength of the tapping teeth, and there is no transition thread; 

The internal thread hole processed by extrusion process has high tensile and shear strength and good surface roughness.
