The great people on this group suggested which QCTP for me to buy for my Atlas 10".? So I got the recommended BOSTAR AXA 250-111 Wedge Type Tool Post Tool Holder Set for Lathe 6-12".? I got it with a 10 piece set:
251-111 (1 Set) AXA Size Wedge Type Tool Post?
250-101 (2PC) Turning & Facing Tool Holder, use tool bits up to 1/2"
250-102 (1PC) Boring, Turning & Facing Tool holder use Tool Bits up to 1/2"?
250-101XL (2PC) Oversize Slot Turning & Facing Tool Holder use tool bits up to 5/8"
250-102XL (1PC) Oversize Slot Boring, Turning & Facing Tool holder use Tool Bits up to 5/8"?
250-104 (1PC) Heavy Duty Boring Bar Holder, can use 5/8" and 3/4" two size shank boring bars
250-107 (1PC) Parting Blade Tool Holder, use 1/2" height parting blades
And (1PC) Two Wheel Knurling Tool can be used separately with any square tool bit holder
?
I am now looking for recommendations on buying the tool bits for this unit and its parts.? I was told by one friend I want tool holders with replaceable carbide tips.? ?I have done some looking online and now am coming here for the opinions of multiple people with actual experience/advice/trusted sources/links etc.? I am a total newbie who has had some fun with just turning down some metal.? I have been told the Chinesium versions are OK for beginners, but not sure if I don't just want to get a decent set right away (without breaking the bank though!)? ?
?
The machine came with some carbide inserts (proper term?) but no tool to attach them to.
?
As always thanks for any help,

Do you have a grinder?? If so, get some high speed steel bits and learn how to grind them.

Learn to grind HSS tool and what angles do what! Many times the old treade powered lathe tool grinds are appropiate for our work. Carbide tooling requires power and rigidity, neither of which the older Atlases have in abundance!?? Bill

?I'm with JT ? & Bill.? ?? Teach a man to fish .... If ya
don't have a grinder yer gonna be needing one soon .Tool blanks
are real cheap & once ya have the angles down ya will just
have to touch them? up usually .? I buy my tool blanks from these
guys
They had a policy were when they got a order they shoved
everything in a small flat rate box till it couldnt tank any more
& then they went to the next size box . There wasn't a bunch
of?? the shipping & handling stuff that is so often a staple
with a lot of companies like to squeeze in on ya just before they
hit the send bill key .

Another vote here for HSS bits and learning to grind them. There are of course always exceptions, but in general carbide does best with high speeds and heavy cuts to get a good finish. With HHS you can make very fine cuts at slower speeds and get a super smooth finish. They are also way cheaper and easily ground to fit the job they are needed for.

What jmartin said. Start there, then once you know what to do with your machine. You can branch out to carbide insert tooling.?

Get a copy(reprint) of the Atlas manual and some HHS cutter bits.? Learn to grind the HHS bits.? Use them and resharpen.? You could get carbide tips but you are NOT ready to use them at this point.? Without special jigs you will not be able to touch them up. The Atlas will cut lots of steel or aluminum.? They are NOT industrial machines even thought they were produced for WWII work.?

Ain't that the truth. I used Clausing Colchester lathes in my class, a few years ago. Teaching machines, so sort of bottom edge af real industrial lathes. The small one, a 13" lathe, weighed 2700# and the 15" lathe around 3800#. My vintage 1946 TH42 is about 267#, and the WWII toolroom SB Heavy 10L is 1067#.?
It wouldn't be unreasonable to call our Atlas Craftsman machines "spaghetti lathes." But people were turning out 3" cannon shells on them during the war. They are quite capable of doing useful work, but need shallower cuts and slower feeds and speeds, than a heavier lathe.??
