Using Tooling 

 
Installing a Turning Tool 

 

Lathe cutting tools are held by tool holders.  
 
To install a tool, first clean the holder, install the tool, then tighten 
the screw clamps.  
 
The quick change tool post is secured to the compound with a 
bolt. Loosen and tighten this bolt to position the tool post. 
 
The tool holder is secured to the tool post using a quick release 
lever. The height of the tool is adjusted with a thumb screw and 
lock nut on the tool holder. 
 
The height of a turning, boring or parting tool should be at the 
center of axis or slightly above.
