Please note this product can only be used with a cordless tool (such as the cordless Dremel) and NOT a plug in model like the 3000 series, due to the danger of electric shock caused by water splashing when cold-working.
These discs should be used wet and on the slowest possible setting. The discs will work at speeds up to 5000rpm as long as the velcro is in good condition
