I just looked at some of the Borite indexible sets *online, I bought a couple sets over the past 1/2 dozen years or so and recommended them above. Unfortunately, it looks like in the past year they might have doubled or maybe more, in price. Wow! So they are no longer the deal they have felt to be in the past, but still good sets.
*edited - remembering mine were acquired from KBC, I checked there. These prices are closer to what i remember paying:
BORITE,BORITE IB500 4PC INDEX. BORING BAR SET,1-512-720,KBC Tools & Machinery

However, note that the picture is not what they are selling (6 bars shown, only 4 in the kit listed) also, check before buying that the inserts come with the bars. They always used to, but i have seen recently where some vendors are selling them separately. Be sure to ask.
But for most of the past 35+ years, i mostly did what Car2 describes, and still do. Also made a lot of carbide tipped bars myself, when the need arose. Some of the best bars i have had were the Everede type, that take triangular HSS pieces. Also Everede HSS tipped bars, that you only sharpen the face, and gradually rotate the bar as it is used up.
If you learn to grind your own tools for the app, it will make you both more productive on odd jobs, and it is very cost effective for the small shop/home shop.
With a 2" head, you are going to be boring larger holes with the bar sticking out the side hole. Just a length of 1/2" round HSS with an appropriate end ground on it works well there. As Car2 mentioned, round tools can be rotated to change the rake, sometimes that will make a big difference.
Do you have a "first project" in mind? size hole(s) and material?

PS, you were posting while i was typing - that set looks ok to get started, if it will bore the range of holes you expect. I can't tell from the photos - it might be necessary to clean up the pockets so the inserts set solidly. Or maybe you'll be lucky. You might still need to grind some small solid bars for yourself, the smallest hole the linked set (& many insert sets) will bore is listed as 7/16". (OTOH, per my edited note above, the Borite set is not a huge cost upgrade so long as inserts are included.)
& Everede still makes some great tools.
If i did not make my own tools, Everede would be the first place i'd shop for small-hole bars.
