Tube Packaged Black and Decker RT1018 36 piece 15/16 inch Emery Cutoff
Wheels. These are very similar to Dremel 409 cut-off wheels. Use with 1/16
inch Screw Mandrel which is not included. 0.025 inch thick. Use with Dremel
rotary tools. Made in USA.
In-Excess had them for 0.80 GBP per tub but I did not buy enough tubs when
they were in stock. Or a similar product say 20 to 36 in a tub, not the
expensive half dozen and a mandrel which are commonly available in model
shops. To cut the steel of an equipment case for a larger pannel switch, or
whatever, takes 3 or 4 of them for one job.
You're using the wrong tool, as usual.
You can't have a sense of humor, if you have no sense.
