• This chuck is available with 3 jaws and is referred as LOC-3. This is light weight lever operated chuck is specially designed for use by craftsmen on instruments, watchmaker’s lathe, bench lathes, grinding machines as well as on small sized machine tools. The body of this chuck is made out of SG Iron to avoid breakage due to slim design of body. The grip of these chucks is limited as the design is without gearing. However this feature has advantage also. The sensitive movement avoids the danger of crushing and have great versatility for gripping fragile materials and components.
