50Pcs 1-1/2 Inch Sand Paper Abrasive Cartridge Rolls Cone Cylinder Rotary Flap Disc 1/4" Die Grinder Sanding Disc Grinding Bits Drum Sanders for Metal Wood Working

Worked good .

I hadn't seen these before, but they are a nice addition to my shop. I have a small pneumatic die grinder that uses sanding discs, but I purchased another one to use specifically with these sanding cones. This should make getting into tight spaces much easier.

Just what we were looking for.

Good pack all together tho in one thing

They work well in small areas .

so far so good

A complete variety of grits needed to do a good professional porting job on a set of heads. Plus it included 2 mandrels. I would like one of the mandrels to be a long one, but oh well. I will probably be able to do two sets of heads with one order. I also use carbide burrs for the roughing stage. Decent value.

I've used hundreds of these from other vendors and have never seen them wear out so quick. The 2 in the center of the picture saw maybe 5 minutes of use in some iron exhaust ports that had a double cut burr finish. Good price and they got here quick but I'll be going back to the more expensive ones.
