Yes, It is a little hard to tell the difference .When you use the screw to fix them , you can find the difference.

Mr K Cooper , I am Hans , I did not use the "Made in USA " products before but buy some products from USA market . About the products I bought , it looks better packing than China local brand . You know a lot China factory manager do not know English well , do not have enough profit to hire a man to just do the packing design job like US company , always just do the OEM factory for foreign company without permission to laser the logo on the products , that is why I can not judge which quality is better just from its packing cause I am not 100% sure they are Made In China or not .

Yes "Ross" , I do use the google translate to translate the thing I want to express , but google could not get the right meaning .

As a disposable-a-blade producer who know a lot about the cutter head , I suggest you buy the Byrd shelix cutter head , it use the radius carbide cutter and have angle with the cutter body , it is quieter than other helical cutter head and have longer blade life . You know if you buy a cheaper cutter head , use more money to replace the carbide cutter , that is ...

The main difference is not the radius face and the laser 1,2,3 but the countersink angle . Other brands can also do Radius face too , they use different mould and different blanks .
