DEWALT vs Milwaukee Angle Grinder Buying Guide
DEWALT vs Milwaukee: Corded vs Cordless Philosophy
DEWALT offers both a capable corded option (DWE402, $94) and a brushless cordless model (DCG413B, $160), giving buyers flexibility based on their job setup. Milwaukee goes cordless-only in their M18 FUEL angle grinder lineup — the 2680-20 ($195) and 2980-20 No-Lock Paddle ($234) — betting that professional users value cordless freedom more than the $35–$100 price premium over DEWALT.
Where DEWALT Wins
DEWALT's corded DWE402 ($94) delivers consistent 11-amp power without battery drain — ideal for metalworkers doing extended cutting or grinding at a fixed workstation. The brushless DCG413B ($160) closes most of the gap with Milwaukee at $35 less, with a similar 4-1/2 inch disc size and compatible 20V MAX batteries. For mixed-use shops where a grinder is one of many tools, DEWALT's price advantage is hard to ignore.
Where Milwaukee Wins
Milwaukee's M18 FUEL brushless motor in the 2680-20 ($195) and 2980-20 ($234) is engineered for sustained heavy-duty grinding — the No-Lock Paddle switch on the 2980-20 is a safety feature DEWALT's cordless models lack. Milwaukee also integrates better with their broader M18 ecosystem if you're already invested in their drills, jigsaws, and impact wrenches. For daily-use tradespeople, the extra $35–$75 over DEWALT is justified by longevity.
Price Tiers
Under $100: DEWALT DWE402 corded ($94) — best-in-class at this price, no Milwaukee competitor. $155–$165: DEWALT DCG413B Brushless ($160) — competitive cordless entry with 20V MAX battery compatibility. $190–$240: Milwaukee M18 FUEL territory — 2680-20 ($195) and 2980-20 Paddle ($234). Milwaukee wins this tier on durability and jobsite safety features.
Which Should You Buy?
Buy DEWALT if you need a reliable corded grinder ($94) or want a solid cordless option at $160 without over-investing. Buy Milwaukee if you use an angle grinder daily on job sites, already own M18 batteries, or need the No-Lock Paddle safety switch for heavy metalwork.

Unlimited runtime from a continuous power source is the core advantage the DEWALT DWE402 11-Amp corded grinder holds on this dewalt-vs-milwaukee page. At $94.00, it undercuts Milwaukee's M18 cordless grinders by $100–140 while delivering consistent 11-amp power that battery-driven tools can only sustain for 20–45 minutes per charge. The paddle switch shuts the tool the moment you release grip — a safety mechanism relevant when disc bind or grinding sparks can cause sudden loss of control. The low-profile gear case fits tighter corners than the barrel-style housings common on Milwaukee's M18 FUEL line. The trade-off is the cord itself: job site work at distance from power panels, on ladders, or in confined spaces favors Milwaukee's cordless flexibility. Choose DEWALT DWE402 for stationary-bench grinding, metal fabrication, or weld cleanup at a powered workstation; choose Milwaukee M18 if mobility across the job site is the actual priority.

Brushless motor for longer tool life POWERSHIFT dual-mode: Speed and Power Keep in mind: tool only — 20v battery required. 4.5-inch disc only — no larger disc compatibility At $160, the DEWALT DEWALT 20V MAX Brushless Angle Grinder 4.5-Inch Tool Only DCG413B costs $35 less than the Milwaukee 2680-20 M18 4.5-Inch Angle Grinder Tool Only ($195) on this page, making it the stronger value pick if the spec differences fit your needs.
“Brushless motor runs 57% longer per charge than brushed. 4.6 stars from 2,773 Amazon reviews signal consistent reliability.”
See Today’s Price →What we like
- Brushless motor runs 57% longer per charge than brushed grinders — significantly more cutting, grinding, and surface prep before swapping to a second battery
- No cord provides true portability for metalwork, tile cutting, and surface prep in locations without accessible power outlets on the job site
- Electronic brake stops the disc in under two seconds when you release the trigger — a safety feature that brushed grinders typically omit
- Kickback detection stops the tool instantly if the disc catches and binds, preventing the torque spike that can wrench the grinder out of your grip
- All DeWalt 20V MAX batteries power this grinder — matches the batteries across your existing DeWalt drill and driver setup without additional purchase
Watch out for
- Tool only (battery sold separately)
- Battery run-time limits very high-volume cutting
- Heavier than corded models

Brushless efficiency at the lowest cordless entry price is what the DEWALT DCG413B brings to this dewalt-vs-milwaukee comparison. At $54.99 tool-only, it is $100–180 less than Milwaukee's M18 and M18 FUEL cordless grinders while retaining brushless motor advantage — 57% longer runtime per charge than brushed equivalents. The electronic brake stops the disc in under two seconds on trigger release, matching the safety standard of Milwaukee's higher-priced FUEL models. Kickback detection is included at this price point, where Milwaukee reserves it for the $234 M18 FUEL 2980-20. Batteries are shared across the full DEWALT 20V MAX platform, so existing drill and driver users pay tool price only. The constraint is capacity: high-volume sustained cutting through thick steel will drain a standard 2Ah battery in roughly 20 minutes. Choose DEWALT DCG413B for occasional cordless grinding within a DEWALT battery ecosystem; choose Milwaukee M18 FUEL if sustained heavy-duty cordless cutting is a regular requirement.

How We Analyze Products
We analyze Amazon review data — often thousands of reviews per product — to surface patterns that individual buyers miss. Our process aggregates star ratings, review counts, and buyer sentiment at scale, identifying which strengths and weaknesses appear consistently across the largest review samples available. The 2,772+ reviews analyzed on this page represent real verified-purchase feedback from Amazon buyers.
Each product earned its placement through data: total review volume, average rating, and the specific praise and complaints that repeat most often across buyers. No manufacturer paid for placement on this page. Products appear here because buyers endorsed them at scale, not because a company asked us to feature them.
We use AI to summarize review sentiment — not to fabricate opinions, but to condense what thousands of buyers actually wrote into a readable format. The pros and cons you see reflect the most common themes found in verified purchaser reviews, paraphrased for clarity. We do not claim to have accessed Reddit, YouTube, or specific publications in generating these summaries.
