The knurl milling tools of the QUICK C611 series can be used on all common long-turning lathes by means of a simple changeover (screwing the adapter onto the appropriate shank). Advantages of the C611-Series knurl milling tools: With the larger knurl millers Ø 14.5 mm (instead of 8.9 mm), greater feed rates and cut values can be achieved with lower wear. Knurls up to Ø 50 mm are now also possible on long-turning lathes.
