HSS inserts exist but they're hard to find. HSS really requires grinding blanks, which not everyone is good at! (But practice helps.)
The inserts linked to by Stueee are for steel. I use them most of the time because they're robust, and switch to this sort for Aluminium if needed to get a decent finish. They work well on steel at slow speeds because they're sharper, but take care because they're also more delicate.
The type linked to is just an example because buying cheap inserts from ebay is risky - they may not be good enough. I've never tried that supplier. I prefer to buy from UK hobby suppliers because their stuff is mid-range, and not as expensive as industrial-grade inserts. ebay ranges from genuine bargain to complete rubbish, so a bit of a gamble!
Part of the fun is learning how to get the best out of your lathe, and knowing when top-quality isn't needed! For example, a shaft on an exhibition engine needs a much better finish than the end of a rod turned down for a force fit on the same engine.
Play with it and experiment. Don't be disheartened if results are poor at first, it takes time - Turners did 7 year Apprenticeships!
