QCTP Holders, Tooling and Setup Tips.

Very helpfull video, thank you for posting.

Wow when I was buying those in AX level they didn't go to 16 yet ! I have the crusher 🙂

Thank you very much Joe for using our products and providing such a detailed description. We invite you to visit us again and discover new products that we have available for you to continue developing new ideas.

Trying to buy what you have . New to all . The ktgpr123a is now ctgpr123a. Bought it. Can you tell me numbers of what insert and chip breaker would be a good start .Kennametal. Also at the end of the 123 there is a A meaning 4 " B meaning 4.5" any ad vantage to 1/2" longer?. Also bought your go to threading grooving any ideas for insert for it for threading. Thanks

Sounds like you are at a gay bar with all those "guys" hanging around your table.

start your video with eye candy like this THEN go too the whiteboard

This will get new people interested-not just your subscribers
Aim for dopamine receptors, bait. usually machines and or motor running-this is key too (more) growth

great explanation- i just bought one to replace my ancient lantern toolpost

I have a Phase II QCTP on my 13" LeBlond lathe. The tool holder numbers begin with 250. Do you know if the Aloris BXA holders will interchange, and is that an acceptable thing to do? Or, should I just stick with the Phase II holders and tools? And once again - THANK YOU SO MUCH for sharing your knowledge with us! Yourself, Quinn and James are my machining heros!

Great video, just got one more subscriber.

I have 1947 Southbend 14 1/2 swing lathe with a 7 ft bed. Looking at the quick changes, both BXA and CXA fall in the range for my swing. It has the lantern style on it now and contemplating the upgrade. BXA is towards the Max and CXA is towards the min for their respective ranges. I am only putting an Aloris on it, she doesn't get any cost cutting corners taken on her. Which one would you get and why?

Wonderful Video
Thank you for sharing... 😎

I bought the Bxa 1s to accommodate my 3/4” tool holders.

Thanks for that. Nice clean orderly shop you got there. Good information for a beginner like me.

I wish I could afford those Kennametal tools, and that they fit my Lathe...
Good tip about using the 'unused' corners of an insert in a milling tool or a different holder in the lathe. Not that I have any scrap carbides, yet...

My QCTP is AXA size, I think. Small... (often sold as 250-000 on Chinesium sites) and the holder can't hold thicker than 12mm tools. Still better than the 4poster that came with the lathe. It couldn't hold better than 8mm tools. (SIEG SC2 mini lathe. )
I have 4 '1' holders right now, but have 5 '1' and a '2' on order right now. I think that should hold me for a while.
But... this isn't my first QCTP. I first bought the SIEG QCTP from the local distributor, and it came with 3 holders. And... couldn't order more holders anywhere! That sucked.
Sure, I could have made do with those 3, but they were also a bit awkward, and if I had to replace the tool in one of the holders all the time, I just decided to ditch it.
(I'm pretty certain it was quicker to change a tool in the 4poster than to replace a tool holder on the QCTP... Yeah, that awkward)
There's a 'mini lathe' QCTH on the market, with similarly-looking holders, but where the adjustment wheel is gold-coloured. It's pretty easy to mistake those for the 250-series.
My toolholders are 250-001 and 002, and there exists others, including a 250-010 knurling holder, too. But there's a 250-1xx series holders, also, and of course, as they're sold by Chinese who doesn't know the difference between a tool holder and a wombat emasculator, it's impossible to find out what the difference is. I probably have to actually buy one...

Great tips!
I really like the idea of using EVERY corner on cutting inserts. Why waste perfectly good corners? Couldn't agree more! :)

Been set up with aloris 1/2 inch shank size tools on my 12 inch atlas but this Logan is a much heavier powerful machine.

Hey Joe,, I picked up an 11 inch Logan lathe what post and tooling do you recommend for it,

Last place I worked they were always throwing out those inserts with 4 good edges on them even though they had holders to use them. I'd always get the other holder and collect several inserts from the scrap bin to do heavy roughing.

Hello Joe Thanks for that info ! some of that I did not know . did you say 40 years ? ha ha ! you
sure do not look that old ! I am 73 and I look it ! Stay young and do not get hurt !

Have you ever used a KDK tool post. It is superior to Aloris. KDK has two independent height adjustments. and I have never needed a height adjustment adapter. Once I put in a longer height adjustment set screw when using a small holder on a big tool post.

I bought 5 of the Chinese knock-off Aloris AXA size holders on Ebay. Not bad, replaced the junk set screws with Unbrako. But not a single one had a height adjustment stud (M10) that was perfectly square.

When I got my new-to-me EMCO Maier V10P lathe in 1991, I quickly became sick and tired of fooling around with shims to get the tools to centre height. At that time I couldn't justify a commercial quick change tool post; thus I made my own.
I used 1/4-20-UNC socket head cap screws for the tool clamps, but quickly tired of these because the socket would fill with swarf that sometimes refused to come out.
At a flea marked one vendor had a small tin can full of 1/4-20-UNC square head set screws. I offered 1/2 the asking price and we haggled a little. Still, the price was quite low. The surprising thing about these screws was their hardness. They appear to be case hardened and will mark a high speed steel blank. Further, the dimension of the square head was also 1/4" across the flats; this was handy because i could use a 1/4" socket extension rod for the wrench.
OH yes, these were cup point screws, and I ground off the sharp edge of the cup.
I still have, and use, that tool post today. I black oxide finished the post and the 30 tool holders, and that finish is beginning to wear off now.

help for even a novice like me w/HF red mini lathe.

Hi. l got on my new pursed lathe simular holders like you show me here but l also get 3 bigger holders as well. they are 120mm long and 27mm opening for the actual tool. lm lokking for 3-4 moore of the big one BUT l cant at al find the name of them. What do l call them? Smal one l belive is named 0250- something (0401 and so one). Bigger verson-l dint know...Yet !!

Hi joe! I’m trying to get my hand on a genuine aloris tool post here in the uk but they won’t send me one! If I send you a fist full of dollars would you please help me out?

Very nice stuff. Good to see the variety of tool holders. Thank you, Joe!

Remarkably insightful - thanks for sharing your passion and knowledge.

Good onfo Joe

Great video. Shopping for QCTP. Piston or Wedge ? Phase 2? How do I determine the proper size post for my lathe ? Thx

Hey Joe, Shane from Oz here.
Thinking about getting a QCTP and not sure of the size to suit my lathe?
I have a 12" swing over bed and thought the BXA would be appropriate, could you tell me if that is the case.
I'm a retired heavy diesel fitter/mechanic but do a lot of my own turning at home for early motorcycle resto's.
Love your channel and presentations, have picked up quite a few neat tips and tricks.
Also, kudos to you for how immaculate and well presented your machine shop is.
Thanks in advance.
Cheers, Shane M.

Hey Joe do you think someone can make money Machining without a CNC?

Very interesting,didn’t know they made so many holders! Yukon👍

Good info Joe thank you!

Joe, can you show us the best way to center your tool on a quick change tool holder. Regards Frank

Hey Joe, second or third time watching this, always great information........I love your sound effect whistle......
Cheers from Florida, Paul

what is the manufacturer or vendor for the milling fixture that uses the other corners of the carbide inserts?

Hey! That was fun, more knowledge than I can take in with only one watching. Will watch again. God Bless

Regarding tool height, I have the opposite problem you have. My tools won't go LOW enough on my Maximat 11. (Maximat 11 carriage was designed to serve as milling table in addition to lathe toolpost. That makes it a little higher, but permits coarse adjustment of tool post, which is most useful for large work!) I have taken tool holders & milled some off the BOTTOM (versus your adding spacer plate under the post to raise it) so I can get the tool "down to" center. I am using AXA1 system, which is the smallest offered. Those parting blocks are way too high on my lathe.
I note that you have machined a lot of your holders (evidenced by milling marks on hardened steel & lack of bluing). It would be most informative for you to make a video about this. I am sure each one has a long & interesting story behind it!

Quick review on determining what inserts fit in holders.

as the new owner of a '56 Myford Super 7 in (really good condition), i am happy to be a new subsubscriber, you have given me more good information in the 5 videos i have watched so far, than in any of the dozens of others i've waded through. thx joe

Good, informative video.
Too much advertising tho.

Love this video. What size tool thanks do I use in a BXA tool post holder?

Would love to see you do a video on selecting the correct insert holder for different inserts and vice versa.

The QTP that was on my lathe (Logan 825) when I bought it doesn't allow any tools larger than 3/8" or I can't get them low enough to get them on center. I'm not sure what to do about that. I'd like to use at least 1/2" tools for greater rigidity.

I just watched this video on qctph and noticed on some of your 3-4 indexable tool holders it looked like the top has been milled or ground. Is that to fit the bxa holders?

Great info.... Thanks for the tips and take care.

I have BXA 250-201 and 250-202. I had already installed some cutting tools and was unable to see the groove in the 202. Thanks to you, I now know the difference. Good source for information for this graduate engineer finally learning how to operate machines and something about the ART involved.
