The heavy-duty 36V hammerdrill/drill/driver, Model DC901KL, was engineered with a 36V NANO phosphate lithium ion battery that provides two times more recharges than traditional NiCad batteries, DeWalt says. The DC901KL features increased levels of power, runtime and performance, while maintaining a similar weight to 18V hammerdrill/drill/drivers, the company adds. The new 36V DC901KL is engineered with an easy-to-use mode section that allows users to easily transition among drilling, screwdriving and hammerdrilling modes.
