As far as I'm concerned, garbage in, garbage out. The use of crude, inaccurate tools to do precise work is fool hardy and much more expensive in the long run. H/F tools, especially their electrical, are good for occasional, home owner's use. I've found little there for a professional environment. I have spent many dollars in their stores and will spend many more but not for things that need to be done precisely or run for any length of time. They have been having their 7 inch variable speed buffers on sale lately and I bought 3 of them with a 2 years, no questions asked, return policy on one of them. They work great for buffing out a finish and if any of the three malfunctions I just need to take it back and get a replacement. Ryobi's fall into this same category. They are for occasional, non precise work. Ask Sherm about Ryobi routers some time. He had one on his CNC for awhile and it about burned his house down. While he was in another room of his shop it caught fire and had the rafters and flooring above it on fire. He just happened to come into the room in time to turn off and extinguish. 5 more minutes and his house and him in the back room would no longer be here.
I used to use a P/C laminate trimmer and was happy with it except for the noise and constant rebuilds. I use 1/32 cutters as most and used to break them fairly occasionally. I bought a Precise, precision variable speed grinder a few years ago. It has run hundreds of trouble free hours now at 40" a min. and never breaks a bit. When the parts get to tight of fit I then replace the bit as I know it is dull.
