QUOTE(ijan @ Feb 18 2019, 04:10 PM) okay la, technically speaking, a 1000W AC motor can lawan a 30cc 2T petron engine output? serves same function, power source saja lain. What say you? Torque dunno. RPM sama. those 32.8cc engine in bg328 grass cutters are rated for only 850W power. that is at max rpm (probably). so a 1000w electric motor with a (usually) flat torque curve across the rpm band should be more powerful (theoretically) than the gas engine.  |

QUOTE(ozak @ Apr 17 2019, 12:04 PM) The carbide drill bit I mention is the whole drill bit is carbide. (include the shank) He's not drilling into concrete.Not the usual concrete drill bit that only the tip is carbide. He's drilling, well he's boring into metal sink. He's already using carbide tipped hole cutter. The shank material carbide or not won't make the tip last longer. |
