15/16" x 0.40" Premium Cut-Off Wheels - High-Performance Metal Cutting Discs for Angle Grinders - Ideal for DIY Projects, Metal Fabrication, and Automotive Repairs

There are a lot of knock off Dremel disks online. I was recently suckered into buying a couple of sets. The first job I used them for was cutting an 8mm bolt. They were unable to complete the job because every one exploded shortly after making contact. I nearly went through an entire set before giving up.The photo shows what one of these low cost disks looks like out of the box. Oversized and offset hole and inconsistent edge. They even break while installing on a mandrel. I’m sticking with Dremel from now on.
