Unknown Tool

Any one know what this cutting blade goes to and what it is used on? These are roughly the side of a handheld grinding wheel.

Looks like chippers for a table saw dado blade, but probably not if only 4” dia.

Could maybe be for use on a shaper.

Never used a shaper, but you could be right.

I'm inclined to think they're part of a dado stack even though they're small.
That's a lot of open space around the cutters for a shaper. Typical shaper cutter heads have a lot less "stick-out" for the actual cutting edge to limit the exposure and the chances of the cutter grabbing the work and flinging it across the room.

Another thought, many years ago I bought a biscuit cutter attachment for a router. I have no idea where I put it but I recall the cutter blade looked something like that. The design of the attachment limited the amount of cutting edge that could be exposed.

Perhaps someone has a more definitive answer.

I am sure that they are chippers from a Dado Set.

They look a little like the tines on a Gravely old style cultivator (tiller). Not for a dado set as normally the chippers are flat and fit between the normal style blades on the both sides of the installed set.

They look to be different thicknesses, so I'm going dado stack chipper blades. But, the small diameter and round middle part is a mystery.

I've seen a similar cutter used on a special machine that hogged out the clearance cutout for forklift tines in pallet parts. Scary looking thing, the 2x4s went through on a conveyor and the cutters were completely exposed. Two sets, one for each forklift tine, and each set made of multiple cutters staggered so they didn't all cut at once. Operator dropped 2x4s on the conveyor which pushed them through, hell of a noise since there was some movement of the board, shower of chips and they were dropped on the floor.

Those things aren't small. Look at the oscillating tool cutter for size. They're like 6-8 inches long. That's chippers for a stacked dado. Or similar wood hogging instrument.

molding shaper?
