Ryobi ONE+ 18V 6-Tool Combo Kit vs DeWalt 20V MAX 6-Tool Combo Kit DCK661D1M1

The DeWalt DCK661D1M1 is the stronger kit. It has brushless motors, a 4-1/2 in. angle grinder instead of a light, and a 4.6 rating from 2,750 owners against 4.1 from 36 for the Ryobi. The Ryobi ONE+ kit is the better entry point for a homeowner who wants a light and the widest battery ecosystem. The DeWalt drill is rated at 300 unit watts out and 1,500 rpm, while the Ryobi drill claims 515 in-lbs and 1,750 rpm, so the Ryobi drill is no slouch. The DeWalt impact driver is the more compact of the two at 5.55 in. front to back.

  • Choose the Ryobi ONE+ 6-Tool Kit if you want a light in the box, a lower entry into a huge 18V battery line, and a drill with a 1/2 in. ratcheting chuck.
  • Choose the DeWalt 20V MAX 6-Tool Kit if you want brushless tools, an angle grinder, and the track record of thousands of owner ratings.

What reviewers say

Ryobi ONE+ 18V 6-Tool Combo Kit

  • 4.1 / 536 ratings

Ratings are decent but not glowing at 4.1 out of 5 from 36 ratings. Buyers tend to value the tool count and shared battery platform for the money.

What people mention
  • ValuePraisedBuyers see six tools, two batteries and a charger as a lot for the money.
  • Battery platformPraisedThe ONE+ batteries work across the rest of Ryobi's 18V lineup.
  • Build qualityMixedThe 4.1 average suggests some owners find the tools less durable than expected.
  • RuntimeCriticisedThe small 1.5 Ah battery runs down quickly in the saws.

DeWalt 20V MAX 6-Tool Combo Kit DCK661D1M1

  • 4.6 / 52,750 ratings

Rated 4.6 out of 5 from 2,750 ratings, buyers treat this kit as a solid way to get six DeWalt tools at once. Most praise the value and the shared battery platform; some wish for more or larger batteries.

What people mention
  • ValuePraisedBuyers say six tools plus two batteries cost less than buying them separately.
  • Battery platformPraisedOwners like that every tool runs on the same 20V MAX packs.
  • Battery runtimeMixedThe 4.0Ah pack covers most jobs, but saw and grinder work drains it quickly.
  • Tool performancePraised

Questions and answers

Which kit is better for a homeowner starting out?
The Ryobi kit. It includes a light, covers drilling, driving, sawing and sanding, and plugs into the ONE+ line for future tools. The DeWalt kit suits someone who also needs a grinder.
Which has the better drill?
Close. The Ryobi drill claims more torque and top speed on paper, but the DeWalt drill is brushless, which means longer motor life and better efficiency under load.
Which lasts longer?
The DeWalt, on paper. Brushless motors have fewer wear parts, and its owner rating comes from far more users. Ryobi's brushed tools still hold up for light home use.
Is the DeWalt kit worth stepping up to?
Yes if you cut metal, grind, or use tools daily. The grinder and brushless motors are real gains. If you mostly drill and drive around the house, the Ryobi kit covers it.
Do the batteries interchange between the two?
No. Ryobi uses ONE+ 18V batteries and DeWalt uses 20V MAX. Each brand's batteries only fit its own tools, so pick the platform you plan to grow with.
Which is better for sanding and detail work?
Both include an oscillating multi-tool. The DeWalt has a 3-speed selector for finer control. The Ryobi has a speed dial and accepts sanding pads for finish work.
