Highlights of the DEWALT 20V MAX Circular Saw

The DEWALT 20V MAX Circular Saw DCS391B impressed me with its powerful 5150 RPM motor, which makes cutting through wood a breeze. The 6-1/2-inch carbide-tipped blade is sharp and durable, allowing me to slice through materials cleanly and efficiently. I especially liked the 0 to 50-degree bevel capacity, which adds versatility for angled cuts, a feature that’s essential for complex woodworking projects. Its lightweight magnesium shoe not only feels sturdy but also helps maintain accuracy over long sessions without tiring my arm too much. The rubber overmolded comfort grip offers excellent control, making it easier to handle even for precision cuts.

  • Powerful motor delivers fast and clean cuts
  • Bevel capacity of up to 50 degrees enhances versatility
  • Lightweight yet durable magnesium shoe for long-term durability

Areas of Concern with This Circular Saw

Despite its many strengths, a few things about this cordless saw gave me pause. The fact that it’s a bare tool only means you need to supply your own battery and charger, which could be a drawback if you don’t already own compatible DEWALT 20V batteries. Also, the 6.95-pound weight is manageable but might still feel a bit heavy for extended overhead work. The keyless blade change is a nice touch, but I found that sometimes the blade lock can be a little stubborn, requiring extra effort to swap blades quickly. Additionally, the saw’s blade size limits cuts to 6-1/2 inches, which might not be sufficient for thicker materials or certain framing tasks.

  • Requires separate battery and charger purchase
  • Slightly heavy for prolonged overhead use
  • Blade lock mechanism can be tricky to operate

Design and Build Quality

This circular saw’s design balances durability with portability in a way that feels well thought out. The magnesium shoe keeps it lightweight without sacrificing strength, which is especially helpful when moving between job sites or working on ladders. I appreciate the brushed finish and yellow color—classic DEWALT style that’s easy to spot in a cluttered workspace. The rubberized handle truly enhances grip comfort, helping reduce fatigue during precise cuts. The compact size (15.5”L x 8.5”W x 10.5”H) makes it easy to maneuver in tight spaces or awkward angles.

Performance in Real-World Use

Testing this saw on various wood types, from plywood sheets to hardwood planks, proved its cutting power and speed. The 24-tooth high-speed steel blade delivered smooth, accurate cuts with minimal splintering. I noticed that the battery life depends heavily on the battery capacity you attach, but with a decent 20V lithium-ion battery, it handled multiple cuts without losing power. The saw’s bevel adjustment was straightforward, and I liked that it could handle aggressive angles up to 50 degrees—great for framing and trim work. Noise levels were typical for a saw of this class—not too loud but definitely not quiet.

Price Performance and Value Proposition

Given its features and build, this tool offers solid value for money among cordless circular saws. While you do need to invest in a compatible battery and charger if you don’t already have them, the saw’s durability, motor power, and ergonomic design justify the overall cost. Compared to corded models, the freedom of cordless operation is a huge plus, especially for those who work on sites without easy access to power outlets. This model strikes a good balance between professional-grade features and affordability, making it a smart spending choice for serious DIYers and contractors alike.

Alternative Offerings in the Market

Comparing this cordless circular saw to competitors like the Makita 18V LXT or Milwaukee M18 Fuel models reveals some interesting contrasts. The Makita saw tends to be lighter and offers slightly better battery life, but it lacks the 50-degree bevel capacity found here, limiting angled cut options. Milwaukee’s model boasts more torque and longer runtime but comes at a higher price point. This DEWALT saw excels in bevel versatility and power-to-weight ratio, making it a better option for users who prioritize angled cuts and portability. However, if you need longer battery life or lighter weight for all-day use, some rivals might edge it out.

Versatility and User Experience

What stood out most during use was how this saw handled different cutting angles and depths. The adjustable bevel settings up to 50 degrees plus the 6-1/2-inch blade diameter allowed me to tackle a wide array of projects, from straightforward rip cuts to more intricate bevel edges. The keyless blade change system, while sometimes a bit finicky, sped up switching blades compared to older models where tools are required. A coworker borrowed it for a framing job and appreciated the comfortable grip and balanced feel, saying it was easier to control than some heavier saws they’d used before. For anyone working mostly with wood and needing angled cuts, this tool shines.

Positive Features That Matter Most

  • Powerful 5150 RPM motor for demanding cuts
  • Lightweight magnesium shoe adds durability without fatigue
  • 0-50 degree bevel capacity for versatile cutting angles
  • Comfort grip handle reduces strain during use

This combination of power, control, and flexibility is what makes the saw stand out in my toolkit. If you ask me, it handles everyday woodworking tasks with impressive ease and reliability.
