I want to order something like this
http://www.use-enco.com/CGI/INSRIT?PMAKA=356-3215&PMPXNO=943270&PARTPG=INLMK32 and a holder for it. There are so many different grades and styles, that I'm completely lost. What would you buy for cutting steel and aluminum on your lathe? |

I just use carbide tipped cutters for everything.
Try ordering some of these, in the styles you need. http://www.use-enco.com/CGI/INPDFF?PMPAGE=162&PMCTLG=00 |

I see that you stumbled onto the TT-321 carbide inserts (love to use them since they are not a arm and a leg for inserts).
Here is a better price on them. http://toolinghouse.com/tt321.aspx. Tool holder sets here in 1/2" shank and larger (but if you check around, may find a less expensive set), http://www.billstoolcrib.com/Toolset5Pc.htm C2: Uncoated grade used primarily in mild cutting conditions. Used for turning and milling steel, cast iron and other non-ferrous metals. C5: For roughing to semi-finishing of Steel. But to add, they are not the end all of tools/cutters. A sharpened HSS cutter will give you a better finish cut, and lets face it, sometimes you need to have a very sharp edge, and an carbide insert cutter is never going to give you such due to the slight radius end of the cutter. |

Always, and I mean always, shop the insert first for price, then work the angle back for the needed holders afterwords.
Take parting cut off insert tools, The inserts for the 19-2 blade (3/4" high, and will have a working depth of 1/ 1/2") are only $2.95 for C-5's, and if you work it right, can pick up a less inexpensive tool holder for the size holder you pick up with a HSS cutter on the cheap (say in the case of needing a QCTP holder), When compared to a Glanze cut off tool with the inserts around $10 a shot, even the Shars full cut off grooving kits with 1/2" conventional holder are not badly priced (if you are not running a QCTP) since they come with 10 inserts to start with. http://www.shars.com/files/products/catalog2011/page75.pdf http://www.shars.com/files/products/catalog2011/page74.pdf |
