NENZ cordless drill
Date:2018-03-05
Cordless drills hit their stride when manufacturers introduced the lithium-ion battery several years ago. These batteries combine huge energy density with light weight and have almost completely replaced nickel-cadmium batteries. Tool companies launched their lithium-ion revolution with big 28- and 36-volt models--tools that had great power but were also unwieldy. Now, virtually all manufacturers have added much nimbler 18-volt and 12-volt models. That kind of shift is PM's signal to get to work, testing to see how well these drills meet a homeowner's real-world needs.
