When compared to the industry's leading corded and cordless circular saws, the DC300K cuts faster and longer than the competition. When tested against other corded circular saws using eight feet of 0.5-inch OSB, the DC300K was able to cut through the material in 5.14 seconds -- that's 20-percent faster than the Makita 5007 and the Skil HD77 corded circular saws. When testing the runtime of the tool, the DC300K cut an average of 224 feet of 0.5-inch OSB and averaged 116 cross cuts of 2x10-inch boards -- two times the amount of the industry's leading 18-volt saws.

This circular saw is designed with a high-power, Dewalt-built motor with an electric brake, which is powerful enough to complete the toughest applications. The DC300K is ideal for trim carpenters, electricians, plumbers and HVAC professionals, as well as for remodeling and framing jobs. Combined with double the runtime of a standard 18-volt saw, the DC300K is sure to bring to new levels of productivity to any jobsite.

Dewalt's Revolutionary 36V Battery
The 36-volt cordless battery platform was developed to provide professional contractors with the performance needed to complete high-powered applications that were previously only possible with corded tools. By partnering with A123 Systems -- a developer of a new generation of lithium-ion batteries developed at and exclusively licensed from the Massachusetts Institute of Technology (MIT) -- Dewalt's 36V line of tools are equipped with a unique Nano-Phosphate lithium-ion design. These revolutionary batteries offers a high level of power, long run-time and durability when compared to conventional lithium technology. In fact, this technology delivers a battery with a maximum life of over 2,000 recharges and no frustrating battery memory. With this breakthrough innovation, this 36-volt tool is sure to live up to Dewalt's commitment to providing Guaranteed Tough products for the professional end user.

Note: Do not try to discharge the battery beyond the point where the tool no longer performs with the power needed for the job. This may cause permanent damage and prevent the battery from taking a full charge in the future. Do not tape the trigger on the tool to discharge the battery.
