FYI, this is a much better deal.

I have two sets now, one will be dedicated to steel, and the other to aluminum.

That set looks pretty good, but I wonder if 1/2" is too big for a AXA size QCTP?
Might need the 3/8"?
It is on a 10" Logan.

edit,
don't see that set in 3/8"

1/2" is max for the standard AXA holders. If you have at least 15/16" height from the top of your compound slide/bottom of the QCTP to your spindle centerline, you should be fine using 1/2" shank tools.

I've had some Glanze tools in the past. I stay away from India made tools but the Glanze stuff is pretty nice. Probably the only made in India tool I would ever consider buying. The indexable holders that Curtis from Latheinserts.com sells are all very nice. Those SCLC holders posted about are made by Toolmex (assuming they have not changed). I just picked up another SCLCR holder today from my local Travers (all mine are Dorian).

My lathe is a HF 8x14 and I run 1/2" tooling with it.

I use The lathe master AXA tool post. It comes with AXA Holders, that have a slightly thinner bottom to get the tools lower for my 8" lathe. Several years ago I purchased a bunch or regular AXA holders and had a local machine shop thin the bases for like $40. Like Will says take some measurement, I would be surprised if they wouldn't work on your machine.

If you don't mind some low resolution videos you can see them in action in this blog post of mine.

I agree with Dan, you should be perfectly fine using 1/2" tools with your AXA on a 10" lathe. I just like to give the dimensions so the user can check for sure rather than say it will work with your lathe....so the user doesn't end up saying "that stupid dz dude said it would work".

Funny you should mention that Dan. I also used to have a HF 8x14 & I also had the Lathemaster AXA set with their modified tool holders. But for me, even with their shorter AXA tool holders, I still was not able to reach centerline with 1/2" tools. I ended up buying more AXA holders & took them all to the engine machine shop I use to have them all milled down to what I needed. I even had the parting Blade holder milled too.

Ok 15/16"?
Thats from the top of the compound, right where the tool holder would sit on?
I will have to measure it.

Yes, that is correct.

Here's another chart

I have this chart in .pdf
Did that just in case website ever changes or disappears.

I did some checking this morning, and I think I might know why.


The Glanze set I purchased back in 2008 measures as 12mm not 1/2". The set I got in December is a true 1/2". I looked them up and the url says 12mm and the page says 1/2" but the part numbers are the same.

After a quick freak out (I hadn't used the new set yet) I check and the new set works, but just barely.

I checked the base of my holders and the old ones I purchased back in 2006 and the new ones I got in December all have a bottom thickness between 0.307" & 0.312". The only exception are 3 new ones that are 0.323" but they are obviously made by a different manufacture as their fit and finish is much better.


What year did you get your lathe? Mine's a 2004, and I wonder if maybe the casting are slightly different, and thus a contributing factor.


On the Topic of inserts, I would advise that people only buy good name brand inserts. If you watch eBay, you can find good name brand inserts for 20-30% of what they retail for. I've used both, and there is no comparison between cheap inserts and good name brand inserts.
