Lathe Form Tool Spring Tool Holder

[jjr2001]

Hello Bony, well yes it is counter intuitive. It works due to the pivot point of the tool bit. With the spring tool holder the pivot point is raised above the cutting tool bit which allows the bit to actually rotate away from the work and relieve the tendency to chatter. It is not that this tool holder is chatter proof but it does reduce chatter and allows you to run at a higher speed or use a heavier tool cut like a wide form tool.

Tom Lipton has a great video showing one that he made for the QCTP and explains it very well.
Here is the link to Tom's video:

Cheers, JR

I just added a short video clip of the tool on the mini lathe using a 1/4" form tool.

I tried this tool without the spring tool holder and
got the deepest mess of chatter I have ever had on my mini.
