No it is not a direct bolt
on accessory. These QCTP use a larger longer shaft than is equipped
on the stock 9x lathes. It is possible is replace the stock 10 mm toolpost stud with a longer
14mm stud. Even with doing this the original cross slide (topslide) is really too small for this
toolpost. There is a height issue with mounting the 39083 on top of the compound slide
shown in the picture below.

How does a QCTP work ?
The Harbor Freight 39083
is a piston type QC tool post. It has a lever that moves a piston
in and out
which in turn applies force to the back of the holder and locks it in place.
There is also a nut on the top of the QCTP that holds the QCTP body in place.
This does not affect the lever that operates the piston.
With the top nut tight the lever will allow you to quickly change from one accessory to another
as shown below:
Any of the QCTP that will fit the 7x metal lathes will work on the 9x lathes.
No modifications are needed except possibly a longer toolpost shaft or a
washer to take up space.
Harbor Freight offers the model 42806 QCTP that will fit the 9x lathe.
Not as heavy as the 39083 but it will work.
Little Machine Shop also offers a TS
The TS Engineering is now a direct bolt on for the 9x lathes
Please note that these two models of QCTP are a lot smaller than the Series 100 QCTP.

What all is included with the HF 39083 QCTP kit
Yes. The HF also offers the 1/2" drill chuck accessory.
What advantage's does the QCTP have over the original 9x toolpost ?
The main advantage to a QCTP is that the tooling can be easily adjusted
to the correct height without having to use shims. You can also change from
one accessory to another in just a few seconds.
With the QCTP mounted directly to the cross slide (shown here)
It makes for a very sturdy toolpost. Important for knurling and parting
which applies a lot of force.
I still also use the original 9x toolpost mounted to the compound a lot.
My cross slide has the 4 bolt clamp which is needed to prevent any flexing.
