Dear XXX,

Thank you for your sent pricelist.

However seems to be that we misunderstood each others because I need the vacuum brazed profile routers in different shape like you quoated for full bullnose type. Please have a look on the attached pictures. I’d need such 2 type of shapes.

One of them is quarter circle ( curve ) ---à 1 / 4 R and other shape is bevelled shape ( cut in 45° degree ).

Please kindly quote for these 2 shapes.

Beside of this I’d have some more questions :

What are the inner diameters of such vacuum brazed profile routers ? d65 mm, d75 mm ….. or what diameter ?

Do you also have such diamond profile routers made of sintered instead of vacuum brazed type ? If yes then could you also quote the unit prices for them please ?

From the edge profile grinding wheel you can make it in silver color instead of red color like you attached picture about it in the offer ?

I look forward to hear about you soon.

Thank you very much,
