4.Wanda Nut Tap Compare With Other Brand
(1).Comparison of shape: Wanda nut tap has a high degree of aliquot groove.other brand made nut tap groove aliquot uneven
(2).From the wear intensity after being processedThe surface finish of Wanda nut taps is as high as μmOhter company made the nut taps on the surface of a significant grinding shocks

Cutting test-1
Brand	Size	Tapping Nuts Number	Taps operating status
Wanda	M8	Up to 50000 threads	As Shown in photo-unusual wear and tear

Cutting Test-2
Brand	Size	Tapping Nuts Number	Taps operating status
Wanda	M8	Up to 100000 threads	After normal wer and tear continue to work after grinding
Other brand	M8	Up to 50000 threads	Taps broken

conclusion: Wanda nuts tap the cutting work life time more than other companies 2-3 times, has reached the international advanced level.
