Anyone know the correct name for this tool?
I received this plate from a retired Mold maker, He called it a lapping plate but wasn’t sure of the correct name. You do not charge it with abrasives like a normal lapping plate. The serrated edges are extremely sharp and used for removing metal.
He said an example of usage would be: if you had to stamp a number into a ground surface - you would then run the part over this plate to shear off any raised spots left by the stamping.
Anyone know the correct name for this plate – or who sells them? I would be interested in any additional information of where and how it is used.
Thanks
Jim

What is the plate's material; soft cast iron or hardened steel?

I am not familiar with any "correct name" for such a tool. Probably means I haven't visited enough obscure corners of the industry.

From your description, it was being used to deburr, so you could call it a deburring plate. You could also call it a manual surface broach. In both cases, you would have to show it to someone before they understood it; the name alone would not work.

Same. Never heard of anything like that. I am guessing it's probably shop-made.

I would call it Frank and I would use it to keep papers from blowing off my desk.

I wouldn't want any part of me near it, that thing eats knuckles.

It does look like a lapping plate, although if its hardened steel probably not. A lapping plate, or lap, is generally soft and is pretty precisely flat. You put abrasive on it (diamond dust or some other abrasive), and use a roller to put the abrasives particles into the lap. Then you put some oil on it. Then you take a workpiece that you want flat/smooth and rub in on the lap. The lap acts like a very fine very flat sheet of sandpaper.

But a true lap would be soft (to grab and imbed the abrasive). Are you sure its not cast iron?

Georgineer, an old grostling hand, can probably provide an ID.

But it's not really cutting burrs, but rather the upsets that form around stamped letters and the like. Kind of like a file laid on the bench. Bench file?

Call it a trade secret and be done with it.
