Review on 🔧 Neiko 30062A Compact High-Speed Grinder by Pete Norris

I had to fit some bearings into a 1.00" drilled hole - the bearing OD was closer to 1.1. I started with a half round file. slow. Bought and some attachments - wow, this little fella packs some punch! The collet needs an extra turn - as others have mentioned, the bit started to loosen on first use. After a good grunt for a turn and a half of the wrench it seems to be holding now. Nice tool for under $20! UPDATE - after several uses. Everything is going well, it's time to take the bit out of the collet - NO - both keys are open, completely unusable. Take 17mm. and change 7/16 to size 11-12mm. and then a thin wall, and now I can pull out what took me a grunt and a half to stay in first place. So - deduction from 5 to 4 stars
