Great for cleaning my goards

I managed to grind through some Glass faster that drilling using Glass drill bits, with no shattering, and was able to enlarge holes with no shattering too.I have also used them it to roughen up the glass and metal surfaces on <bleep> idiotically smooth Glass body, metal/plastic top, Salt and Pepper Grinders, so that they can be reliably gripped, even with damp hands.

Great course burrs.Important... do not use these for outlining they are very course.

Sehr schnelle Lieferung!!Sehr gute Qualität!!!
