This rough boring cartridge set is listed for a 95.0-116.0 mm boring diameter range with connection designation 36. It uses the CCMT1204 insert family and screw-on clamping. The selected item is a set of two cartridges.
Overall length is 74.0 mm. The insert-seat data lists a 12.7 mm inscribed circle, 5.5 mm insert hole and 12.9 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.
