I fit most of my tools into the serious tool cam handle. I have the model that accepts 3/4 adapter sleeve. Mine is not a collet but a sleeve adapter style. Since these sleeves are no longer available, I make my own sleeves out of 3/4" aluminum or steel rod when fitting a new tool. I also use it with 3/4" boring bars which are quite common in the woodturning marketplace. Aside from having individual handles for each tool, I find this system the fastest to change tools with. There are no set screws or knob to turn when you want to remove the tool from the handle. I find much easier and a hugh advantage to sharpen the tool without the handle attached.
here are all the tools that I adapted for the Serious tool cam handle. Also, I made some smaller handles. Note the tool on the far left is a home grown 3/4” adapter sleeve.
