As a supplement tocommon screw-fitting tools, the holding forces betweenthe tool and arbor system act over the full surface of theentire shrink grip connection, and large portions of theshrink grip thread. See the assembling instructions for theDuoPlug ® in the “Technical Data” section for furtherinformation.It’s a fact:DuoPlug ® perfects threaded connections with significantlybetter holding force and the highest precision, at extremelynarrow dimensions.Your benefits• increased process reliability• longer tool life• significant reduction in vibrations with long overhangs• facilitates the highest precision in finishing operations• high availability for the tool system and improvedprocess reliability• improved performance in roughing operations• high durability and red hardnessIdeal applications• high-precision finishing operations• finishing and roughing work with long overhangs• machining situations on vertical walls thanks toextremely narrow arbor systemOrder / request formsSpindle systems / shrinktechnologyAssembly instructions17Index
