If cheap tools for occasional use is what you want, rather than tradesman-quality, then Harbor Freight may be the cheapest source.
Some of their tools work well enough and others are utter rubbish. I've had good luck with their $10 and $16 angle grinders (4.5 inch). These draw 4 amps in contrast to a quality $100 tool that draws 10-11 amps so don't expect too much, but any angle grinder is better than none! In addition to one for grinding, I have a wire brush on the cheapest one
($10, blue) and a cutting wheel on another. I found this cuts better freehand than mounted in their hinged cutoff accessory.
That cutoff assembly was completely useless as bought. It is clearly a copy of a better one but the table is so flexible that forcing the blade into the work bends everything out of alignment long before the motor loads down. Its cam-lock vise is a joke, it reaches the end of travel before the object is secure then slips open as soon as a cut is begun. I get some minimal use out of this piece of junk using c-clamps to flatten the platform to the corner of the bench and another to clamp the work object rigid relative to the workbench.
I also bought their 6 inch angle grinder and find it is better for finish work, a little wimpy for removing material. Then I got the 9 inch version and that works great for ripping off metal - beveling for a weld or creating a unique shape. Total cost for all these grinders was under $100.
I have their $59 tractor Quick Hitch and the $180 motorized 50 ft sewer cleanout snake. These both work fine and were well worth the price.
Welding Web has a
HF forum where good and bad HF tools are discussed. I would read up on a specific tool there before spending any money.
