The small milwaukee have “variable speed” and seems smaller, probably lighter and less powerful than the bigger one ( same size as my ryobi) probably the tool you search for lap working. I grind/cut my laps with my sander polisher mid to low speed, 6” or better 5” 80grit, but a lighter tool for this job should be more confortable to use here. I had the idea, if possible, to convert a small 5” orbital sander to a rotative for this job so i can easily connect my vaccum cleaner. Never take time…
It’s funny, but the die grinder that used to cost $19 is now about $45 in the Harbor Freight catalog. And; They added a trigger lock. Which can be gotten used to, but makes the tool a little difficult to use. No longer a “grab and go” tool. That trigger lock can be removed. I guess demand drove the price up. Looks like the same tool. All metal, no plastic.
I have noticed many Habor Frieght tools have gone up in price, not just due to inflation. Many items are no longer “grab and go”.
They are making an effort to improve quality of their tools. That Bauer line of tools is definitely better quality than the Chicago line. They have been doing TV adds that brag on their quality.
