carbide grit sanding blade.

[sparkeyjames]

My father the toolman of the family has a blade for his RAS that is a blade coated with what apears to be soldered on carbide grit. This is on both sides AND the edge. Has anyone seen anything like this recently? He has had this thing for ages and it still works like new.

Sounds to me more like an abrasive cut-off blade. For Ferrous metals or masonry. which is why the abrasive on both sides and the edge.

Might not be good for a RAS, some parts might melt from sparks when cutting steel or iron. There are Chop saws that look like a miter saw, for cutting metal, but with metal shrouds and stuff, but the blades are more or less interchangeable with circular/table/RAS/CMS saws in that they have a diameter and an arbor hole.

I've seen hitachi blades at the blue box for jig / recip saws that have that type of grit on them

Nope this was just for the RAS and sanding. It I do believe is not a cut off saw. the grit is too spread out and of rather medium to large grains. Blade is a copper color but not pure copper a brazing aloy of sorts I guess. It has no metal or carbide tips or teeth like a regular saw blade.

Abrasive cut off blades have no teeth.

Let me see if I can describe this thing better. 10" diameter. Soldered on carbide or diamond ,though my father says carbide, grit maybe 60 or larger grain size. Base blade is a hard metal. Rings nicely when thumped with finger. Grit or more likely grains as they are spread out almost like a spattered on thing and are soldered with some sort of coppery gold/brass colored alloy from edge up to 1 or 2" (from memory) away from arbor hole on both sides. He told me at the time he bought it late 60's early 70's it was VERY expensive.

google "carbide grinding disk" and you'll probably find what you are looking for. they seem to be for grinding ceramics and concrete.
also try "tungsten carbide grinding disk"

porter-cable makes a paint stripper that uses a similar disk.

If you don't get your answer here, I would think the DeWalt radial arm saw forum could help:
