Tee (and others): after completing a project that needed some repeated drilling in steel plate (2mm thick) I quickly realized that the CXS chuck - the new one - isn't really up to snuff on drilling metal, we are talking small holes here.
After a few agonizing tries I had to break out the T12+3 and it breezed through the task.
When I did a comparison between the TXS and the T12+3 I thought that with the C12 battery (only 1,5Ah though) the T12+3 is almost the same size and is quite a lot more capable. Much as I love the CXS for assembly work and small tasks I find that the C12 Li and T12 combo is very hard to beat for what I do.
A Festool dealer had a close out sale on them both at around HALF price on Basic and Set versions so I took custody of two of them, one C12 and one T12, one set and one basic.
I swapped one small battery over from the C12 to the T12 box and one larger battery. They came in handy as I was completing a project where I was pressed for time and needed (yes, really) three to four screwdrivers on site. I didn't even bring the CXS pair out and I was extremely happy with the C12/T12, I usually bring out a big gun for every on site work but I left the DRC out of the loop this time and didn't miss it for this task.
Until the CXS will be upgraded to brushless I am keeping them at the shop, there have been a few times where they have been out of their league even for smaller tasks. They are still super handy so there is always one around the house and in the shop but for on site work I have removed them from my set up. They might still tag along for very specific tasks but as it stands right now they are shop bound. I have no patience for chucks that can't take some heat.
