Thread: Older style Angled Parting tool holder ?

Hi , a general question here ,I have been out of the trade for quite some time now, My 20 yr old lathe is a bit worn ,but ok for non critical work My question is I am after one of the older style parting tool holders which were angled similar to the attached picture, they used to take a high tensile holder with a carbide tip braised on , the main advantage is that under load they could give a little ,unlike HSS which can fracture ,especially with a dig in . I have done some searching online but no luck so far ,any body know if these types are still available ,and if so any ideas where ?
My lathe is quite heavy duty but with the old belt drive pulleys and back gear has an 8" chuck and adjustable tapered headstock bearings ,I get a bit of chatter with my current parting tool , and not enough speed for insert tools ,
The ones I remember had a side plate for clamping the tool ,this one pictured is for a back tool post, but the principle is the same I think. Cheers ~ John

A mate of mine who retired from being a toolmaker a few months back gave me some parting insert type blades bit no tool holder. I did do a google and found that they are still available but cant recall where (in OZ to I think)...but being so simple I decided that when I need it I will make one...in the mean time I am going to make a tool holder that willl hold eccentric's parting blades

Yep ! that's the one , as you say simple and easy to fabricate ,getting some blades may be a problem ,I will keep looking ,there may be a number stamped on the ones you have that may help in that Cheers ~ John

Thanks for that info, it's a starting point, a quick look around so far no success , might have to try antique shops and museums lol.

Perfect thanks heaps ,will contact Blackwoods They may have the holders as well if not I will fabricate one Cheers ~ John

Update thanks for the responses , Blackwoods wanted $40 each for theirs and had no stock in any case , I rang my old boss and he made a few suggestions and the upshot is I now have 2 blades from Carmet here in Brisbane for $50 ,no holder as they wanted $150 for theirs, highly over engineered I feel hehe, so I will go the fabrication route , cheers ~ John

You're a bit late, there was about 10 of them on ebay about a month ago. $15.00 posted. A bargain. Quite nice condition as well. Tipped tool in mine was good too.

Hi ken,
Missed it completely, must have been either poorly named or I just plain missed it.....I'll blame the Holbrook, it has chewed up all my attention

Ew

I don't see the advantage of this type of parting tool holder, if using a brazed tip with it.
When using a HSS blade that is tapered top to bottom, it does have the advantage that the mounting angle translates that to also provide some side clearance.
That is, it effectively has a reducing width from front to back.
The shape and size of the ground curve needs to be considered for best action, but at least it's easier than grinding tapered side clearances.
But, a brazed tool bit can be a bit wider than the blade, so doesn't need more side clearance.
Am I missing something? Does it have some sort of "gooseneck effect" as well?
