I'm looking into buying a Chester Craftsman lathe. There is however a small problem with the online manual Chester offer on the forums. It has next to no information about the actual lathe, and is more a general overview of lathes and the functions. I have found Grizzly make a very similar lathe, the G9249.

Setting the stage. I am a no experience beginner, about to take possesion of a Clausing Colchester VS13x40 lathe. I need a recommendation on where to start with toolbits. Should I start with HSS grind your own, pre-ground carbide, carbide insert holders?
And is indexible? Then based on the type, what size bits, or insert holders should I start with.
I know the standard answer is it depends on what you are machining. Again, I am just looking to purchase what I need immediately to cover begginer's excersizes in basic machining. I started out with one of those sets of carbide bits with the different angles and shapes in 3/8' size. I have since found out that I prefer the blank/grind myself HS 3/8' cutters.
The HS cut almost as good, don't chip when you screw up and are easier to sharpen. Plus you can easily grind one the way you like. They are cheaper too. I started with a HF 7' X 10' lathe. Free Virtual Games Like Habbo.
Moved up to a HF 9' X 20' and now I have a Cincy Hydrashift 15' X 54'. I still like the 3/8' size bits. A good source for the bits is ENCO or Grizzly also good for other machining tools and supplies. Chuck, that's a loaded question. For a beginner I think your better off with HSS tool bits.
3/8' is better for your size lathe and 1/2' is as big as you need. For best results you could get Cobalt HSS tool bits. The reason is they are easy to grind and are forgiving. Search the used book sites for a copy of How To Run A Lathe put out by Atlas Lathe Co.
It is basic and teaches a lot of good stuff. Craftsman also sold them. Buy a copy of Machinery Handbook. It don't have to be new, as a mater of fact an older copy is better. Say a edition 15 to 24. Carbide is great and good for fast metal removal, and often gives a better finish if you have an adequately ridgid and powerful machine, But IMHO, you need to first learn the fundamentals on tool bits with HSS. It's cheaper to buy, more forgiving to mistakes, and you have the whole tool bit to experiment with, unlike the carbide tip on a brazed carbide too bit.
There, when that tip is ground away, what's left is scrap! Home Machinist, not to be confused with Home Shop Machinist, has had a series of threads on the grinding of HSS, featuring writings by member Harold V, with comments and questions by other members. One member even went so far as to compile a synopsis of these threads into one and posting it there. I've been in the trade more than 40 years, and I found it interesting, informative, and authoratative (sp?).
Visit and do a search. Here's a wild idea but hear me out. Go to the McMaster catalog and find the lathe tool section. They have pre-ground HSS bits of various square shanked sizes, in many different configurations. I believe they are manufactured by Armstrong. Pick out a couple of bits, they are of course going to be more expensive than the blanks you hog out on your own, but study how they are ground and study how they cut.
