Yeah, that's what I thought when I bought the 8" (on sale, of course) -- most of that "heft" is empty space!! I discovered that when it fell over and shoved the shaft out one side (the bearing retainer is pretty light gage metal, so it just ripped out.)

Surprisingly low torque. The rotating mass helps via flywheel effect if I shove the work in too hard, but it's slow to recover. In fact, from a dead stop, it takes more than 15 seconds to reach full speed.

I use it primarily for light grinding on HSS, so the slower RPM is more important to me than the power.
