This is a review of a very inexpensive Quick Change Tool Post (QCTP) set for 7x mini-lathes that can be purchased on Ebay for about $38 (including shipping). It is considerably less expensive than similar size QCTPs that you can find on LittleMachineShop.com and Amazon that cost about $135 to $155 plus shipping.
I purchased it because the cut-off blade holder for my 10-year old A2Z CNC QCTP had broken and I needed another one ASAP. I didn’t have time to fix it and I couldn’t buy a replacement because the company has gone out of business. My set was on loan to the SparX 1126 FIRST Robotics Team, where I am a mentor, and it was getting heavy use because we were in the middle of the build season.
So, when I came across this cheap QCTP set on eBay I decided to take a chance and buy it for the team. The same set is sold by many eBay vendors and I chose this one and paid a higher price, $45, because they were promising delivery sooner than most other vendors and the seller has a high rating.

It’s manufactured in China and it comes with four tool holders – two identical holders for turning and facing bits, a ?-inch boring bar holder and a holder for ?-inch cut-off blades. The tool post is made almost entirely from hard anodized aluminum and the tool holders are made of steel. In comparison, the $135 QCTP that Little Machine Shop sells for 7x lathes is made entirely of steel and it includes an additional holder that can knurl in addition to hold another tool bit.
