The item has a very good quality, and the service ( shipping costs, communication, etc) is perfect. I'll always buy this items from shop-apt, the best tool shop i have ever used!
These inserts fit the Glanze 12mm clamp-type parting tool - Glanze code them as CGGSP on their site - they look fine - I bought them as replacements for when required and I haven't used them yet - Delivery was lightening. Company comms were good too. Don't worry about the 2mm width quoted by Glanze and the 2.1mm quoted by this company - the cutting tip width is 2.26mm and 2.28mm respectively on my example! their measurement must refer to the body of the insert I guess - both items look identical
