This fine boring cartridge is listed for a 39.9-51.1 mm boring diameter range with connection designation 22. It uses the TPGH1103 insert family and screw-on clamping. The selected item is one cartridge.
Overall length is 26.9 mm. The insert-seat data lists a 6.35 mm inscribed circle, 3.4 mm insert hole and 11.0 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.
