Specifically designed for special repair sleeve coldworking processes and applications
Special repair applications — The CR series was originally developed for rework applications, but can also be used for new fastener holes ranging from 3/16" to 13/32" (4.8—10.3). When coldworking a previously countersunk hole, the hole should be processed using the next larger tool size. See Section VII for tooling tables. Applied expansion is higher than CB tooling, which allows the use of fewer tool sets to coldwork a range of holes. A full set of CR tooling is available in kit form as the CWORK2B.
