Best Cordless DeWalt 20V MAX Circular Saws

TL;DR: The DeWalt DCS571B packs a brushless 20 V motor, 4.5‑in blade and 1.5‑in depth at 90° into a 6.6‑lb, compact body that excels in tight‑space, finish‑carpentry work.

This saw’s standout feature is its brushless motor paired with a 20 V MAX battery platform, delivering the efficiency of a cordless tool while keeping the weight down to 6.6 lbs. Its overall length of 17.88 in and height of 6.69 in give it a grinder‑sized footprint that fits comfortably in one hand, and the 4.5 in blade lets you make precise cuts in plywood or composite decking.

Compared with the other five circular saws in the roundup, the DCS571B sits in a unique sweet spot. It’s a touch heavier than the DCS565B (6.3 lbs) but still lighter than the larger‑blade DCS573B (8.2 lbs). Its blade is smaller than the 7‑¼ in blades on the DCS590B and DCS573B, and even a bit shorter than the 5.5 in blade on the Lezzyruck model, while the HLiePiHa’s 4‑in blade is slightly smaller. In terms of overall length, the DCS571B is longer than all peers, exceeding the 15‑in‑plus bodies of the DeWalt‑branded rivals and the 14.76 in length of the Lezzyruck unit.

Users consistently praise the tool’s lightweight feel and the ease of one‑handed operation in cramped spaces. Reviewers also highlight the solid battery runtime—up to 369 linear feet of 3/4 in OSB per charge—and the on‑board dust port that keeps work areas cleaner. Professional reviewers note the electronic blade brake and brushless motor as reliability boosters. The main trade‑off is the limited 1‑in depth at 45° and 1.5‑in depth at 90°, which means you’ll need to make two passes to cut through a standard 2×4.

Additional technical touches include tool‑free depth and bevel adjustments, a 1‑½ in finger trigger for precise control, and a side handle that can be removed for tighter maneuvering. The dust collection adapter and included rip fence round out a package aimed at finish carpenters and DIY homeowners who value portability over raw cutting power.

Best for: Most users looking for a well‑reviewed, reliable mainstream option — the DeWalt DCS571B offers Bevel Capacity: 0‑45 Degrees

Avoid if: You need a primary saw for framing or must cut full 2× lumber in a single pass.

TL;DR: The DeWalt DCS565B packs a brushless 4,950 RPM motor into a 6.3‑lb, 6½‑in cordless saw, delivering solid power and a 0‑50° bevel range for most jobsite cuts.

What really sets this saw apart is its brushless motor paired with a no‑load speed of 4,950 RPM, giving you quick, clean cuts while preserving battery life. At 6.3 lb it’s lighter than the DCS571B (6.6 lb) and far lighter than the 8.2‑lb DCS573B, making overhead or one‑handed work less tiring.

Compared with the other five tools, the DCS565B offers a larger 6½‑in blade than the Lezzyruck’s 5.5‑in blade and the HLiePiHa’s 4‑in blade, but it’s still smaller than the 7¼‑in blades on the DCS590B and DCS573B. Its 0‑50° bevel capacity exceeds the 0‑45° range on the DCS571B and Lezzyruck, yet falls short of the 0‑57° offered by the DCS590B and DCS573B. The no‑load speed is lower than the 5,500 RPM on the DCS590B and DCS573B, but higher than the 6,200 RPM on the Lezzyruck and far below the 12,000 RPM on the mini HLiePiHa.

Professional reviewers praise the tool‑free bevel adjustment, electric brake and LED lighting for safety and convenience on the jobsite. Users appreciate the compact dimensions (8.5 in H × 15.25 in L × 9.63 in W) that fit tight spaces, while the spindle lock and magnesium shoe add durability. The manufacturer lists dust collection as false, so you’ll need an external dust extractor if you need a clean work area.

Best for: Most users looking for a well‑reviewed, reliable mainstream option — the DeWalt DCS565B offers Bevel Capacity: 0-50°

Avoid if: You need advanced features or professional‑grade performance, especially for heavy 2×12 framing where the limited cut depth may be restrictive.

TL;DR: The DeWalt DCS573B packs a brushless 5,500 RPM motor, 77% extra power with FLEXVOLT, and a 7¼‑inch blade into an 8.2‑lb, 0‑57° bevel‑capable cordless saw.

What really sets this saw apart is the FLEXVOLT Advantage, which delivers up to 77% more power when you pair it with a FLEXVOLT battery. Combined with a brushless motor that spins at 5,500 RPM, the tool can cut through standard and heavy‑duty lumber quickly. It carries a 7‑1/4 in blade, a 0°‑57° bevel range, and weighs just 8.2 lb, making it easy to swing for framing or cross‑cut jobs.

Compared with the other five models in the roundup, the DCS573B is heavier than the 3‑pound HLiePiHa mini saw but still lighter than many full‑size corded options. Its 0‑57° bevel capacity exceeds the 45° limit on the DCS571B and the 50° limit on the DCS565B, giving you more flexibility on angled cuts. While the budget‑friendly Lezzyruck measures 14.76 in in length, the DCS573B’s 15.375 in length provides a slightly longer grip without adding bulk. The tool also includes a blade out‑of‑the‑box, unlike some lower‑priced competitors that ship without one.

Professional reviewers praise the ergonomic layout, smooth bevel stops at 22.5° and 45°, and the electric blade brake that stops the blade instantly when you release the trigger. Users note the trade‑off that the optional dust port and the Tool Connect tracking chip are sold separately, and that performance on a standard 20 V MAX battery isn’t as punchy as when paired with a FLEXVOLT pack. Still, the 20 V MAX platform ensures compatibility with all DeWalt 20 V batteries you may already own.

Additional technical highlights include a 5/8 in arbor, a maximum cut depth of 2 in at 45° and 2.5625 in at 90°, an integrated LED light, and a built‑in rafter hook for easy hanging on the job site.

Best for: Buyers willing to invest in a proven, high‑quality option — the DeWalt DCS573B offers Bevel Capacity: 0° to 57°.

Avoid if: You're on a tight budget or need a dust‑collection system included in the box.

TL;DR: The DeWalt DCS590B packs a brushless motor, 1,700 W output and 5,500 RPM into a cordless 7‑¼‑in saw with 0‑57° bevel, delivering corded‑like power for demanding framing jobs.

The DCS590B’s standout spec is its 1,700 W maximum output, which professional reviewers highlight as matching the performance of many corded circular saws. Coupled with a 5,500 RPM no‑load speed, the brushless motor keeps the 7‑¼‑in blade spinning fast enough for clean cuts through 2× lumber. Its 0‑57° bevel range, complete with 22.5° and 45° stops, lets you tackle compound cuts without extra accessories.

Compared with the other five saws in this roundup, the DCS590B sits at the premium end of the price spectrum, making it pricier than the DCS571B and the budget‑focused Lezzyruck model. It also offers a larger 7‑¼‑in blade versus the 4‑½‑in blade on the DCS571B and the 5.5‑in blade on the Lezzyruck, and its bevel capacity exceeds the 0‑45° limits of those two competitors. While the DCS573B shares the same blade size and bevel range, the DCS590B adds a higher no‑load speed of 5,500 RPM, matching the DCS565B’s speed but with a bigger blade.

Consumer sentiment points to strong satisfaction with runtime: the tool can achieve up to 368 cuts per charge when paired with an 8.0 Ah battery, and the electronic brake adds safety on the job site. The main criticism comes from the tool‑only configuration, which forces owners to buy a compatible battery and charger separately. Reviewers also note that the manufacturer doesn’t list the saw’s weight, leaving portability a bit of a mystery.

Beyond raw power, the DCS590B includes Tool Connect™ compatibility (chip sold separately), letting you track usage and receive maintenance alerts. The 20 V MAX* (nominal 18 V) platform means it works with the broader DeWalt 20 V ecosystem, and the 5/8 in arbor size matches a wide range of replacement blades.

Best for: Those prioritizing quality and willing to pay for premium performance — the DeWalt DCS590B offers Bevel Capacity: 0-57°

Avoid if: You're on a tight budget or only need basic functionality

TL;DR: At $45.49, the HLiePiHa Cordless Mini Circular Saw packs a 4‑inch blade, brushless 12,000 RPM motor and ergonomic grip into a 3‑lb, compact body, but its 0.8‑inch cut depth limits heavier jobs.

This mini saw’s standout feature is its brushless motor that spins at a no‑load speed of 12,000 RPM, delivering quick cuts through soft wood and plastics. It drives a 4‑inch blade and reaches a maximum cutting depth of 0.8 inches at 90°, while an ergonomic handle keeps fatigue low during extended use. The tool also offers a 0‑45° bevel range and comes with two blades right out of the box.

In the six‑product roundup, the HLiePiHa is noticeably lighter than the DeWalt DCS565B (3.0 lb vs 6.3 lb) and the DeWalt DCS571B (3.0 lb vs 6.6 lb), making it easier to carry around a job site. Its overall dimensions—9.65 inches long, 3.74 inches wide, and 3.94 inches high—are also more compact than the Lezzyruck Cordless Circular Saw, which measures 14.76 inches in length and 5.9 inches in width. However, the HLiePiHa’s 0.8‑inch cutting depth is shallower than the deeper cuts offered by larger peers, so it’s best suited for light‑duty trimming.

Users who already own DeWalt 20V MAX batteries appreciate the low entry price and the convenience of swapping batteries between tools. Reviewers note the high RPM motor makes fast work of trim and hobby projects, but several comments describe the build quality as feeling “cheap” or “generic.” Professional reviewers echo this, praising the speed while warning that the limited 20 mm depth restricts the range of materials you can handle.

Technical details reinforce its niche role: a brushless motor paired with a 20 V system, three speed settings (8,000 / 10,000 / 12,000 RPM), and a safety lock for added confidence. The ergonomic handle and lightweight chassis aim to balance portability with enough power for occasional DIY tasks.

Best for: Shoppers on a tight budget who want the most for their money — the HLiePiHa Cordless Mini Circular Saw offers Bevel Capacity: 0-45 degrees

Avoid if: Reliability and user satisfaction are your top concerns

TL;DR: The Lezzyruck Cordless Circular Saw offers a brushless 5.5‑inch blade, 0‑45° bevel, and 1.9‑inch max depth for $63.95, making it a compact, budget‑friendly option for light woodwork.

This saw’s most distinctive spec is its brushless motor paired with a 5.5‑inch blade and an idle speed of 6200 RPM. The ergonomic handle and adjustable bevel from 0‑45° let you make precise angled cuts, while the 1.9‑inch maximum depth at 90° gives you enough material removal for most DIY projects.

Compared with the other five models in the roundup, the Lezzyruck is longer than the HLiePiHa Mini Saw (9.65 in vs 14.76 in) and carries a larger blade (5.5 in vs 4 in). Its no‑load speed is lower than the HLiePiHa’s 12,000 RPM, but it still out‑cuts the DeWalt DCS571B, which only reaches a 1‑1/2‑inch depth at 90°. The DeWalt DCS573B boasts a 7‑1/4‑inch blade and deeper cuts, but it sits at a much higher price tier.

User sentiment notes that the compact blade makes the tool easy to maneuver in tight spaces, and the brushless motor is praised for efficient power delivery. However, reviewers point out that the battery isn’t included, so you’ll need a compatible DeWalt 20 V pack. The limited cutting depth also means it’s less suited for heavy‑duty framing.

Best for: Buyers in the budget price range seeking the best quality at that price point — the Lezzyruck Cordless Circular Saw offers Bevel Capacity: 0-45 degrees

Avoid if: You need advanced features or professional‑grade performance
