International Builders’ Show Product Preview: DeWalt Nano Technology Cordless Tools

Nanotechnology refers to the control of matter sized as small as a nanometer—a billionth of a meter. But DeWalt hopes its new Nano Technology 18-volt DC927KL hammer drill and DC827KL impact driver will be a big hit on the shelves.

DeWalt’s nano-phosphate lithium-ion battery boosts power for its weight as well as life—2,000 recharge cycles, claims the manufacturer. The 18-volt cell fits every other 18-volt tool DeWalt has made since 1996, and the charger also works on the company’s earlier 18-volt or lower batteries.

The hammer drill costs $369, while the higher-torque for impact driver runs $349; each comes with two batteries and charger. Four- and six-tool 18-volt kits are also due this spring, and DeWalt also sells 28- and 36-volt Nano tools.

Our recent report on cordless drills found DeWalt’s 36-volt drill, $450, capable but pricier than several models that outscored it overall. We’ll see how the 18-volt Nano fares in our future tests.—Robert Markovich
