In this video I cut through a metal bolt with a cordless Dremel rotary tool Model 800, 10V lithium, 35,000RPM. I use cut off wheel number 426, it's a standard metal cutting disc that is reinforced with fiberglass for durability. You can find cordless Dremel tool at Amazon (affiliate link): amzn.to/2srTxRM
The concept of the original Dremel tool was to rotate a bit at high speed; the bit being held in a collet. Variable speed versions may cover a range of 3,000–37,000 RPM. The Dremel concept relies on high speed as opposed to torque unlike a conventional power drill, for example. By inserting an appropriate bit or burr the tool can perform drilling, grinding, sharpening, cutting, cleaning, polishing, sanding, routing, carving, and engraving. Both cordless battery powered and corded models are available.
