402 owner reviews, fewer than most models here
The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less. The bars below show where this model stands against the other power tools and workshop machinery we track in this category on price, popularity and size. Context, not marks against it, and our read of the data, not a lab test.
Overview
The CRAFTSMAN CMCW400B runs on an 18V battery platform and spins bits at up to 30,000 RPM, making it well-suited for chamfers, roundovers, and decorative edge profiles on trim work. At 4.1 pounds it handles comfortably for extended single-handed passes along a workpiece edge. The $88.97 price covers the bare tool only, so buyers without existing CRAFTSMAN 18V batteries should factor battery cost into the decision.
With 402 verified reviews and a 4.8-star rating it ranks among the most trusted compact routers in the category. The 2-amp draw is modest for a cordless platform, which contributes to solid runtime on a charged battery for typical trim-routing sessions. Owners who buy about 200 units per month signal consistent, practical demand rather than a flash-in-the-pan listing.
Because specs do not list a variable-speed dial, all routing happens at the fixed 30,000 RPM top speed. That works for most trim-bit work but limits versatility with large-diameter bits that typically benefit from lower speeds. Pairing this router with a quality bit set makes a meaningful difference in cut quality and heat management.
Pros
- 4.8-star rating from 402 reviewers signals very high owner satisfaction
- 30,000 RPM top speed handles standard trim bits efficiently
- 4.1-pound weight is easy to manage for one-handed edge routing
- 18V cordless platform eliminates cord tangles during trim work
- Competitive $88.97 bare-tool price for a well-reviewed cordless router
Cons
- Bare tool only; buyers without 18V CRAFTSMAN batteries face added cost
- No variable-speed spec listed, limiting use with larger-diameter bits
- Light 2-amp rating may mean reduced power in harder hardwoods compared to corded options
