This rough boring cartridge set is listed for a 42.0-51.0 mm boring diameter range with connection designation 18. It uses the CCMT0602 insert family and screw-on clamping. The selected item is a set of two cartridges.
Overall length is 33.3 mm. The insert-seat data lists a 6.35 mm inscribed circle, 2.8 mm insert hole and 6.45 mm cutting edge length. These describe the insert geometry, not the cartridge mounting-hole diameter.
A complete boring head, shank and insert grade are not established as included. The insert family is a partial designation; grade, chipbreaker and nose-radius selection remain application dependent.
