DEWALT DW758 8-Inch Bench Grinder

Q: I'm confused by the claim this grinder 3/4 horse power. A 4.4 amp,120vac induction motor is 1/6 hp per various engineering charts and 3/4 hp 13 amps??

Horsepower is often used to compare electric, internal combustion, and hydraulic power, but you can't really convert one to the other without considering the load and duty cycle. 4.4 amps in a 120VRMS circuit is 528W of electric power. 750W is 1 hp... again, in electric power. So from the power company's point of view, it's a 3/4 hp motor (528/750=0.7, close enough). Throw in power factor, efficiency, and delivery loss and you are probably down to half a hp or so of mechanical power.. but certainly not as little as 1/6. From an engineer's point of view, it makes a big difference if you're going to power a chemical mixer for 12 hours at full load or sharpen a lawnmower blade for four seconds and then let the motor cool for thirty seconds.

Q: What is the size of the retaining nut that secures the grinding wheels on this unit? 1" is too small. 1-1/16" too big. Is it metric?

1 1/16 socket will work if you don’t have 26mm

Q: Is the tool rest adjustable to any angle?

Yes, it is adjustable but it needs a better way to loosen and tighten it, other than using open-end wrenches. I have seen other models that use a clamping style closure and after 3 years I think I'll weld up my own to match theirs.

Q: Is possible to remove one wheel to attach another wheel?
