Deloro Stellite bit

[Massimo DalmonteParticipant @massimodalmonte45801]

Hello everybody,

a few days ago, I purchased from eBay a bit of Deloro Stellite (grade 100) with the intent to use it on my lathe.

Just out of curiosity, I'm wondering if some member of the forum can identify its original purpose, as I'm not sure it was intended as a lathe toolbit.

Cheers,

Massimo

Massimo, Tell us how thick it is please. This would be a great help! By the way, it gets very hot when you try to grind it!

Hi Massimo,

have used Stellite once – many decades ago – to machine some stainless steel. It was in the form of a square toolbit (like HSS toolbits), but was harder. I formed a cutting edge on the grinder. Your toolbit seem to have a different form, so I am not sure what it was made for. As Clive says, it would help to know the thickness.
Today I just use carbide inserts.

Excuse me, Clive and Thor, I just forgot …

5 millimeters thick

Just a guess, but it could be intended as the pointer for a height gauge/scriber. It would work very well as one if the tip has the knife edge it appears to have from the picture.

I am wondering if it is one of these woodworking rotary cutters, they have inserts and possibly it is a groove cutter? The angle of the pointed end looks about right for wood working..

Some time ago I picked up a box of Stellite welding rods as part of a job lot. So far I have not used them, Does anyone have experience with them?

I use stellite number 6-rod to gas weld a deposit for tough facing on my cam follower the followers on Triumph twins are also stellite tipped.

It’s also used on valve seats and reclaiming poppet valves.

There are various numbers for different hard facing applications.

The best use for Stellite welding rods is for facing Plough shares so you need to find a Farmer and maybe get a nice job off him. It does not matter how rough the weld is as it is the wear property that matters.

Hi everybody,

it's seems to me that Neil's guess is pretty close ( I was "looking" at the bit in the wrong way, because of the markings, as my pic shows…), only argument against it is that those scribers often have a swan-neck form, but some seen on the web are like this one.

Clive, I thought of it too, but there are no relief angles ground on the bit (perhaps they are not needed for wood?) and there's no positive way to reliably retain it, in case it was rotating at high speed, as is usual for wood.

Good evening,

Massimo
