Some context. I have landed a small little side job for a local metal worker. He despises using a grinder enough he hired me to do what he hates.

Just because I don't know, but a straight die grinder should rotate clockwise if one is looking directly down into the collet correct?

Silly question, just couldn't find a straight answer other places.

it will rotate the same as a drill bit in a drill--clockwise from holding the die grinder in your hand, but looking into the collet end would be counter-clockwise---Dave

I thought something felt off, this one is spinning backwards then.

The polarity on the cord is correct. Might have to take it apart further and see what's up. Any thoughts?

possibility of having a forward reverse switch on it but I wouldn't think so---if it has collet for gripping the tool then as long as you know which direction it is turning you should still be able to use it---what brand is it? --Dave

Hold on guys. Most cutters are designed for a specific rotation..No?

The brand is Dayton.

I tool it home and took it apart, the wiring was fine. I had the thought that the field poles might've been screwy, wires were jumbled up and crammed in there. I removed and rotated the field assembly 180', reassembled and now it rotates in the proper direction. It's getting better rpms now, problem was fixed.

Weird, but problem solved. Not sure why that fixed it, learned something new.

yes most all are--- except round stone burrs wouldn't hurt to run in opposite direction--He has it running now in the correct rotation so his problem is over---Dave
