Which is better for a homeowner doing DIY projects?

The 3-tool FLEXVOLT kit fits general DIY better because the circular saw handles lumber cuts and the 6.0 Ah batteries run longer. The ATOMIC kit is the cheaper start if you already own a saw.

Which has longer runtime per charge?

The 3-tool kit, with FLEXVOLT 6.0 Ah batteries. The ATOMIC kit's largest battery is 5.0 Ah, and its second battery is only 2.0 Ah.

Is the 3-tool kit worth the extra money?

Only if you need a circular saw and long runtime. At $399.00 at Home Depot versus $140.00 at eBay as of November 4, 2026, the ATOMIC kit is far cheaper for drilling and driving alone.

Which is better for tight spaces?

The ATOMIC kit. Its hammer drill is DeWalt's shortest 20V hammer drill, and the DCD708 drill weighs 2.4 lbs.

Do both kits use the same 20V MAX batteries?

Yes. Both run on DeWalt 20V MAX lithium-ion batteries, and FLEXVOLT batteries work in 20V MAX tools, so batteries carry over between kits.

Both use brushless motors, so tool life is similar. The 3-tool kit's 6.0 Ah batteries hold more charge and take fewer recharge cycles for the same work.

DeWalt ATOMIC 20-Volt Lithium-Ion Cordless 2-Tool Combo Kit vs DeWalt 20V MAX Cordless 3-Tool Combo Kit with FLEXVOLT 6.0 Ah Batteries

Buy the ATOMIC 2-tool kit if you want a drill and impact driver for tight spaces at the lowest price. Buy the 3-tool FLEXVOLT kit if you need a circular saw and longer runtime from 6.0 Ah batteries. The ATOMIC kit's best new price is $140.00 at eBay as of November 4, 2026, versus $399.00 at Home Depot for the 3-tool kit. That is a $259 gap, so the 3-tool kit only pays off if the saw and bigger batteries are must-haves.
