Shank question.

[Kbeitz]

I got this box of shanks from the junkyard. Box is marked new but they are far from that.
It says F8 on the box. Does anyone know what they might fit ? Are they worth keeping ?
The box has a date of 1013 stamped on it. Some of the teeth look in good shape.

Simonds Saw shanks. F8

Those appear to be worn out bits in shank boxes.

[Kbeitz]

I guess I could weld them to a circle and make a de-barker.

[dustyhat]

Kbeitz, i have welded them to the end of a small shaft and reground them for a boring bar for aluminium,worked out pretty good just keep it cool so the carbide dont come of.

[Don P]

No carbide there, looks like they do fit my saw, holler if you need more  :D

[Kbeitz]

These bits are carbide. Two chunks on each tooth. The carbide is soldered in a L shape.
Putting it under a magnifier you can see the carbide is in two pieces .

I never used carbide, but those don't look like they've ever been sharpened.  Any life left in them?

Some look great. Some are chipped. I think they would be great to use for
media in a deburring machine. To good in my eye to trash.

So an idea is born and the Kb Debarker begins.   ;D

Yep those are carbide and yes they are whooped as far as sawing is concerned. I use the same bit. I'll send some pics of new vs old as soon as I get a chance

Thanks...

Those bits are JUNK as far as sawing is concerned.  Absolutely wore down to nubs. If new they would have had almost 1/4 in. of carbide on um.

[JB Griffin]

The carbide when new would have been simply a small rectangular block with an edge bevel not L shaped.

[Kbeitz]

Why then is the carbide made with two pieces ?
I will get a measurement tommorow but I'm sure the carbide
Is over 1/4" in size

[JB Griffin]

I ment in thickness.

[JB Griffin]

Not sure why the two pieces maybe they cracked after being ground so thin?

[longtime lurker]

TCT is very hard but quite brittle: once they get too thin cracks appear and thats replacement time.

[Kbeitz]

This is not cracked. Every tooth has two chunks of carbide soldered to
the shank. The front carbide is 1/2" long.  I'm not saying they aren't junk
but I will find a use for them.

I think you mean brazed instead of soldered.

Could you make a flycutter out of one of those? Or some kind of tool for your lathe?

[Jeff]

You are using the term shank incorrectly. Shanks are the semi circular part that holds the bits in the saw. They also form the gullet. You have bits that were put in a shank box.

I thought they was silver soldered?

Thank you ... I was going by what it said on the box.

I can't tell by the photos and the few that I've seen were all brazed.

Can you scratch it or wire brush it and see whether it's silvery or brassy looking?

[Kbeitz]

Looks silvery to me under a magnifier...

[grouch]

Well, silver soldering stands up to hydraulic fittings, why not saw teeth. Learn something new every day.
