These are the right size to work on intricate molds, models, and castings. They are SMALL and can easily reach into areas not normally accessable to even modeling files. I would definitely purchase these again.To those reviews saying they are smaller then they appear, Duh! They match the physical description for size. They small enough to reach into tight spaces. My only request is that they be made in smaller grit sizes as well to provide a polishing look.
