Better if you buy a set, but mine were still £50+ for 1-13mm in 0.5mm steps

Still, they only come out the box for tough stuff

I actually have a set of HSS, plus a set of Titanium coated (nicer on ally) as well.

Different tools for different jobs.

we work almost only with stainless & have never had any problem drilling ,however it can happen that the drill wasnt sharp or wrong speed & the drill can burn & then what happens is that alot of the drill matirial stays in the hole & makes the steel immpossible to brill (so the inside of the hole can get as hard as the drill itself when it burns).

Made them from steel bar in the end,easy to machine and for the use they will get, probably last a lifetime.
