Our tool cuts the tube at one end of the condenser, separating the two rolled ends and can
be used to trim excess tube from the boiler tube face sheet.

tube cutting configurations, each designed to meet your specific needs.
Cutting adapters are available in sizes from 5/8″-14 BWG through 1″- 24 BWG. 2″ nominal depth of cut. Special larger and deeper sizes available upon request.
