Lathe Tool Bits

[JLMullins]

I am brand new to this. I bought a mini lathe from Harbor Freight #93212. I am try to figure out what tool bits to use for what. I see different type during searches but can't find an explanation of their use. Does some one have a link to a page that shows the different bits to use. I got some bit at Harbor Freight they are carbide but not the indexable type. Does someone have pics with explanations of what each bit is used for?

Thanks,
Jimmy

Something like this, you mean?



I just did a quick google image search using "lathe tool profiles" as the search criteria, lots of pics come up. There's also good info in both the Southbend and Atlas lathe manuals if you have copies of them. You should get at least one of those manuals anyway if you're just getting going on using a lathe. Extremely beneficial.

You'll find out very quickly you're going to be grinding a lot of different profiles for different work. The chart Francist posted if only the start Stock up on HSS blanks if you can. Believe it or not some Harbor Freight stores carry HSS blanks in their stores. 5 tool bits for $5. Can't go wrong.

Use a tool that will accomplish the work needed, the only requirement is that it works for the intended application, for example there is no reason not to use a "TSC" shaped tool upside down running the spindle in reverse if that is all that you have and it works.

Thanks, what these different type of tools used for that I got at harbor freight? I can't seem to figure out what shape does what and what the A,B,C,D,E= (60 deg Thread I believe). I know the L&R is left and right.

Thanks I bought a bunch of HHS blanks. Just need to learn the shape to grind them to and the angles.

OK here I found something I hope will help. What is each of the type tool bits used for? Is there a place on the internet I can find this info?

Thanks,

Thanks I bought a bunch of HHS blanks. Just need to learn the shape to grind them to and the angles.

Bench grinder for roughing and an oilstone for honing are all you really need, many different types of angles and grinds to experiment with.
