I wanted to buy a set of Festool drill bits for drilling steel. I bought the 492512-492518 ones after reading in their description:
So that mentions metal. However, the packaging has a little forest icon, and it also says "3 CE/W" which makes me think W stands for wood.
On the back of the package are two tables of drill bits, the first one again with the forest symbol and all sizes of the "CE/W" bits, exactly the ones I bought. Then there is a second table where it says "CE/M" (for Metal?). That table has a metal beam symbol, which makes me think those are for drilling metal. The numbers on those are listed as 493421-493428. Their description sounds similar, but they seem to have a reusable shank.
Should I have bought those ones instead? Does the CE/M vs CE/W distinction mean anything? What about those symbols?
