I had a think about it greatest torque would be in low gear so that's rated at 550rpm much lower than the 2200. So my calcs show at 550rpm and 84ftlbs of torque we make 8.8hp with no load does this sound reasonable for a small drill?

Ok so i think i messed that up because if we assume 300rpm then by lowering the rpm would mean we no longer are making 115nm so our hp level would be lower.But i still question the max torque of 115nm can we assume that's happening at 2200rpm? If so no load were making close to 35hp?

Ok so with no load i will still be making 115nm in the drill correct spinning at 2100rpm? Even if the drill spins at 300rpm underload with 115nm torque i get close to 5hp Thats that's quite a large petrol engine in comparioson (briggs and stratton etc)

Thanks for your reply here's the link for the impact gun https://www.makita.com.au/products/lithium/lithium-ion-skins/18-volt/dtw1002z-18v-mobile-brushless-1-2-impact-wrench What about for this drill you would think that the 114nm would be matched to the rpm? 114nm is still comparable to a...

Hi i have a question regarding torque with impact guns and high torque drills. So i just bought a impact gun which is rated at 1000nm at 2200 rpm how can this have such high torque were my cars engine makes only 400nm at 2500rpm So i guess my question is how can we compare these torques to...
