Parting tool holder
Parting tool holder
I have a pile of GTN2 parting inserts.
I had a toolholder like this: but the problem is that the lower portion is not well supported and it actually snapped off.
Tool was cutting great - right until it wasn't cutting at all.
I don't get why they just don't make the underside larger - it's not like it's going to get in the way.
Went to this style: which has much better support, but not useful on larger diameters.
I'm looking for this type: but I'd like one that has a 1/2" mount so that I can get it into an AXA toolholder, which has a 1/2" limit.
Most of them are 3/4' to 1".
I'd also like to get one that doesn't cost $100.
Anyone know of a good deal?

I've used these for years - they even work well with 4140 3/4"+
I wouldn't be surprised if your inserts would fit

Re: Parting tool holder
How about something like this, a self-contained cutoff toolholder. The height will have to be changed if you need to extend or shorten the stickout to accomodate deeper cuts or for more rigidity.

I have two of those and they are a pain to use because, as you mentioned, they need to have the height changed when you move the blade.RMinMN wrote: ↑Fri Feb 14, 2020 6:17 am How about something like this, a self-contained cutoff toolholder.

Also, they don't accept the holders for GTN and other parting inserts.
I have a machinist-made one that hods that type of blade horizontally. Much better. Don't know why they don't make them this way.

Banggood's search on their website is awful. The more terms you put in to narrow the search, the more results you get because it uses "and" instead of "or".
You put in "cutoff" and you get two pages of results. You put in "cutoff lathe tool" you get 14 pages.

Last I knew, Iskar used a tall, very thin support "tool holder". These holders could plunge the cutting bits deeper into stock. If it ain't wide, its tall and the compound removed .

Is not just Banggood, there are many companies that do not understand the issue.Banggood's search on their website is awful.
Parts that are mostly characterize by dimensions need to have a dimension selector.
I do not want to look 97 pages of randomized ball bearings or gears to find the one I need.
As for the inclined T blade holder. Mine sticks out 1/2" which will cover 99.5% of the parting I do. resetting when needed is not so complicated but for that I probably switch to the insert type tool, the blade is 1" deep and straight horizontal.

The advantage of having the two that I have is one is set deeper, so I just swap toolholders.tornitore45 wrote: ↑Fri Feb 14, 2020 9:50 am As for the inclined T blade holder.

That works for my HSS parting blades, but I'd like to use these inserts. They work really well. On brass and aluminum I don't even have to go into backgear.

Re: Parting tool holder
That's because they are designed and made for has cut off blades. The angle gives you built in positive rake.
Re: Parting tool holder
There are actually blades for those that take GTN inserts, but the smallest holder they will fit is a BXA, probably because they would be too fragile when cut down enough to fit the AXA parting toolholder. Steve

Re: Parting tool holder
Make a holder! I have 4-5 of those insert holders ,one of which resides in a shop made holder block which is 1/2 " The rest are 3/4 which fits my Multi-fix style post,they can take up to 22MM = a bit over 3/4" Bad thing is I have at least 3 different styles/widths of inserts !

Why not make one that fits your needs?
