New tooling for lathe, totally overwhelmed.

If it were me:

Sandvik (as well as others) makes some good stuff. It's all I use for the most part on barrel work. This is after fiddling with a variety of other brands.

VBMT1604 04 PM for facing/turning

TLT3R for threading

CXS06T098206215R for boring/cone breech operations.

These are just the inserts, you'll need to order the corosponding holders as well.

Generally the inserts run about 17.00 a piece. You buy in a pack of 10.

The boring bars are about 40 a piece. They are sold individually.

Holders run around 100 each.

You'll probably want a parting tool as well. My suggestion is get a rigid style that will reach only as far as you need it to. I've never had real good luck with the adjustable ones.

The boring bars work awesome for crowning as well.

Good luck.

I have been using the Diamond Tool Holder for some time now. Have not found any areas where it just isn't superb. The only time I change cutters is to crown a muzzle or to thread. I have a special ground bit that an old gunsmith that taught me lots made for me. I treasure it like a jewel! And I thread with a carbide insert tool.

The Diamond Tool Holder is one of those tools that you simply can't appreciate it until you use it. I've had lots of seasoned machinists over to the shop and challenged them to grind me a tool that cuts better. No one has beat the DTH yet. Sure, they can grind some nice tools, but it takes them quite a bit of time. I resharpen the DTH and I'm back to work in seconds......
 
Some of the tooling I use I found on my own and some of it others suggested and or showed it to me and let me try it out.

Here is my list of what works for me:

Circle Industries QCBI-375-6-5R Carbide Boring Bar w/TPCH-2205-CG5 Inserts. Bolt counter bores.

Circle Industries FCBI-250-4-5R Carbide Boring Bar w/TDAB-505-CG5 Inserts. Pre-boring chambers.

Kennametal E08SDUPR2 Carbide Boring Bar w/DPGT2151HP KC5010 Inserts. Sharp high positive insert. Crowns, cones.

Kennametal SDJCRF082D Turning Holder w/DCGT2151HP KC5010 Inserts. Sharp high positive insert. Relieving root of tenon at shoulder for recoil lug clearance.

Iscar SWAPR-1414-06 Turning Holder w/WPEX060402R08 IC908 Inserts. Finish turning tenons.

Seco MWLNR-10-3A Turning Holder w/WNMG060408-M3 TP200 Inserts. Facing and roughing tenons.

Iscar SER0625H16 Threading Holder w/IC908 coated inserts. Threading tenons.

I'm with the original poster, a little overwhelmed with tooling options. I've always been able to borrow a lathe until now.

Buying a Grizzly G4003G. What can folks recommend for a starter tooling package? It already has some of the bigger items including a quick change toolpost. I'm needing bits, holders, bars, threadturning, etc. I really don't want to buy too much more than the basics to get going but a kit already put together would be perfect. I'm guessing I'll be sticking with HSS unless there's a need later for carbide.
 
Ditto on the Diamond Tool Holder

Roy, I agree with you on the DTH, it's great!:p

Like you said, "It's one of those tools that you cannot appreciate until you use it."

Most people have never heard of the DTH; I know I had not until a few weeks ago. For more information go to Google and type in Diamond Tool Holder. You owe it to yourself to check this one out!

Ordered a B16 yesterday via the internet. Upon further reflection, I wonder why they don't offer the B16 using a larger bit like a 3/16. My lathe has a 12" swing so the 1/4" bit will be fine but if I had a 16" swing or more I would probably like a bigger bit.

You will find that the 1/4" tool supplied with the B16 size Diamond Tool Holder (DTH) is ideal.

My lathe is a 13 x 40 and I use the B16. It will take much deeper cuts than I like to use. It may seem that the 1/4" tool is too small but remember that it is mounted tangentially to the work which makes it much stiffer. Trust me; you will love the DTH.

Thanks Gene. And a big DUH to me, I meant 5/16 not 3/16. I watched the video and was impressed. Have you tried it for threading yet?

I am confident with the HSS bits but I have not used the new carbide technology, so that aspect adds to my lack of knowledge.

It seems as though many are using the HSS bits, and so I will likely continue using them. I may try a cheap indexable just to see what happens.

I would like to try one of the (cobalt?, IIRC) bits that is already ground for internal threading. I can't grind one for what they cost.

Thanks everyone for all the good information.

just a note carbide has been around for at least 50 yrs. not really new technology.for yourself being that production isn't really an issue high speed will be fine if you want to cut time from job go to carbide.

No, I have not tried the DTH for threading. I use a carbide insert tool for threading and am very happy with the results.
