Leaps in battery technology, especially lithium-ion, let cordless tools pack more power. Now, other improvements are driving the tools to become more compact.
"The actual motor performance is getting better, and we have the ability to deliver more power out of a smaller motor," says Shane Moll, vice president of marketing for tools and equipment for Milwaukee Power Tools.
As well as freeing users from the limitations of cords, these compact tools can be slipped into a toolbelt or pocket, freeing the worker's hands. And less weight means workers exert less energy.
"People are looking to get as much work done as easily as possible with little fatigue," says Steve Jenson, a product manager for DeWalt. Among those who would most benefit from these tools are roofers, electricians, HVAC installers, and window installers. Most of the compact tools are coming out on the 18-volt platform, which many experts call the "sweet spot" for pros and dealers. The tools most affected are drill/drivers.
Ridgid released a compact, cordless 18-volt lithium-ion drill/driver that weighs 4.25 pounds and has 455 inch-pounds of torque. An older nicad 18-volt drill weighed about a pound more but produced only 5 inch-pounds more torque.
Makita's cordless lithium-ion drill/driver delivers 450 inch-pounds of torque, weighs 3.5 pounds and is 8 inches long. An older lithium-ion model weighed about a pound more and was 1-3/8-inches longer but had 110 inch-pounds more torque.
