MQL Tool Holder Kits
The missing link
Unist MQL Tool Holder Kits fit into most common CAT and BT style tool holders. The MQL optimized retention knob and MQL tool holder insert ensure proper aerosol delivery from the end of the spindle to the shank of the tool. The retention knob is specifically designed to interface with the fluid delivery tube and the tool holder insert. The tool holder insert greatly reduces the effects of rotation on the aerosol inside the tool holder, delivering a more consistent MQL output.
How it works
When the tool holder is loaded in the spindle, the end of the fluid delivery tube is inserted into the MQL optimized retention knob. Air ﬂowing past the end of the fluid delivery tube creates the MQL aerosol and carries it through the MQL tool holder insert to the shank of the tool. The consistent-diameter path prevents the ﬂuid from being centrifuged away from the shank of the tool.
The tool holder insert is threaded into the MQL optimized retention knob and is available in a variety of sizes and lengths. The installed tool contacts the tapered portion of the insert forming a seal. The tool holder insert determines the tool offset length.
