    I've had 2 of these for a number of years and they are great. They were a common brand in automotive machine shops that did custom head porting. Not sure if they are still heavy in that area.

    I have a single speed, corded, Makita and a variable speed, 20v, cordless, DeWalt in addition to my pneumatic ones. I prefer the Makita when I need lots of power, otherwise I grab the DeWalt for the variable speed and portability. Kinda wish the Makita was variable speed too.

    The Bosch I was initially interested in has a top speed of 9000 rpm.
    Do you gentlemen use the full 20k+ rpm's I'm seeing on other brands and find those speeds a requirement?

    Yes. If you use small grinding stones, cutters , 1 inch flap wheels, 2 inch rotoloc etc you need the speed.

    If you are using larger (3 inch+ ) bushes or disks, no.

    I have a Makita and a couple of
    Dumores. The Makita turns about 20k rpm and the Dumores about 37K rpm. I actually prefer the Makita for most work. Both are sensitive to the size and stickout of a mounted stone. Too big a stone or too much stickout and you run the risk of the shank taking a right angle bend right at the end of the collet. It gets kind of exciting then, trying to hold on to the tool with both hands while to shut off the motor. The Dumores are great for using smaller carbide burrs.

    Sounds like you might want to put on your brown corduroy trousers in case your shank bends.

    You made such a compelling argument you'll be pleased to know I did purchase the Makita.
    Variable speed up to 29000, a clutching arrangement on the arbor in case I bury the cutter
    and a paddle switch.
    What more can life offer?!
