Perma-Grit Cutting Disk Set

I used these in addition to the Dremel sanding drums to contour the edges of some hand-made carbon fiber parts. The cutting wheels made easy work of getting through the carbon fiber composite and also has the added benefit of being able to sculpt or chip away very small areas and radii using the edge of the blade with all of the embedded tungsten carbide material. These are pricey for sure, but I suspect they will last quite a while and I definitely see the benefit after just a few uses. "Regular", abrasive discs are a little too flimsy and wear away a little too often to do what I was trying to do with the carbon fiber. These stood up to the task brilliantly.

Received the item quick from Wicks Aircraft Supply... Needed something to cut 1 to 4 mm carbon plate, and have experience with PermaGrit products. These cutoff wheels are working great so far. :-) Will probably order more PermaGrit rotary tools soon. :-)
