I've tried the TPG holder for the Aloris and frankly I find it wanting. True the inserts are about as cheap as one can go with carbide inserts and are about as common as flies on a sugar pie. The Aloris holder I feel is far superior is the D80. Uses CNXX4XX seies inserts. Four cutting edges versus the TPGs three. But one does not have to spend the money for the Aloris. If you can pick up a used 4XX series CN-16/20 style tool holder it can be modified to fit an Aloris (or any of the other knock-offs or competetors on the market). If you really need the clearance the TPG can give think about modifying a DN-16/20 series tool holder
Forty plus years and I still have ten toes, ten fingers and both eyes. I must be doing something right.
