Iam the market for a new drill and impact driver. Iam leaning towards Milwaukee 18 volt. I read somewhere that 20volt and 18 are the same performance. Just marketing,,,,,,Anyone agree? :thumbsup:

At the end of the day you get what you pay for regardless of the voltage. Many years ago I had a Porter Cable 12V drill that was nearly $250. It outperformed the cheaper 14 and 18 volt drills on the market.

Is the 20V drill a Milwaukee unit also?

20V max batteries average 18V over their discharge cycle (that's called nominal voltage), just like ones labeled 18V. Marketing. Milwaukee does it too, M12 is really 10.8V

20v is just peak voltage. It's really 18v. Marketing hype. AH will determine the time the battery will last more than the difference of a few volts. Brushless is much more efficient battery wise then brushed (normal) motors.

it is kind of like your car battery, at a full charge the battery will have 14 volts but is rated at a 12 V. the 18 volt batteries will have 19.6 volts at a full charge so some call them 20 others call them 18 which is the average voltage it will produce . it is really only a difference between average and Maximum voltage, but 18 - 20 are basically the same,
