Re: [falconKB] Harbor Freight Angle Grinders

The grinders that you listed are all single speed and need to be modified (remove shield). What you want is a sander. I bought a couple of HF variable-speed 7" sanders about 5 years ago (the model is no longer avail), and have used one almost daily without any problems. The backup has never been out of the box. The choice of tool is really based on usage and what you can afford. If you're in a production mode, you want to get the best - something that is very reliable and has a proven reputation for producing good work. Same is true if building boards is something you'll be doing for the next 10 years. For doing a few boards a year or repairs, the HF model 92623-1VGA is OK. I have one and you can sand and polish with it. For $29, you won't find anything retail that is as good, but you'll need to get a collection of power pads and spend more time sanding to get results like a Milwaukee. As Herb Spitzer previously recommended, you should clean out and repack the gearhead with a good grease. I recommend Slick 50 PTFE grease which is available at most auto supply stores. I also have a HF model 90820-1VGA sander; it's only 2 speeds, very heavy, but has a lot of torque. I use this only for polishing. Be advised that backing pads (Power Pad, Ferro) are more than the HF sander itself.
