A dremel is a small electric power tool thats like a minature die grinder. It spins at up to 20,000 RPM. Many tupes of bits, burrs, stones, drums, wheels, etc. can be chucked up in it. A thin abrasive cutting disk may be chucked up in this tool and used to make a very controlled narrow kerf (width) cut. The disks will cut (grind through) about anything metal. They make sparks and shatter if you overload them or side load them. Wear eye protection and gloves. There's almost certainly an English equivalent tool or maybe even the "Dremel" trademark type available there. Check in hobby stores or consumer tool outlets. Cheers, Jim
