Makita 5377MG Magnesium Hypoid Saw Review Powerful Lightweight Circular Saw Performance

Description

Highlights of the Makita 5377MG 7-1/4″ Magnesium Hypoid Saw

After putting the Makita 5377MG 7-1/4″ Magnesium Hypoid Saw through its paces on various woodworking tasks, I’m impressed by its blend of power, durability, and lightweight design. The magnesium components make the saw incredibly well-balanced and noticeably lighter than many circular saws I’ve handled, weighing in at just 13.2 pounds. This weight reduction doesn’t sacrifice toughness; the saw feels solid and jobsite ready, which is crucial when you’re cutting through dense materials all day.

The 15 AMP industrial motor with its hypoid gearing system delivers consistent power, making quick work of both dimensional lumber and engineered products like LVLs and I-joists. I found the 4,500 RPM speed and the oil-bath sealed gears particularly valuable, as they ensure smooth operation without the hassle of frequent maintenance. This setup really stands out for those who value a tool that can last through heavy jobsite abuse without breaking a sweat.

Pros

• Magnesium components ensure a lightweight yet durable build
• Powerful 15 AMP motor with hypoid gearing for smooth, consistent cutting
• Large cutting capacity: 2-3/8 inches at 90° and bevel up to 51.5° with positive stops
• Oil bath technology eliminates the need for regular gear lubrication
• Includes a premium ultra-coated carbide-tipped blade that cuts cleanly and lasts long

Areas for Improvement

• The corded design limits portability compared to battery-powered saws
• The handle, while ergonomic, might feel a bit bulky for users with smaller hands
• The saw’s price point is on the higher side, which might not fit every budget
• No onboard dust collection system, so dust management requires an external solution

Ergonomics and Ease of Use

The ergonomic design of this circular saw deserves a shout-out. There’s generous clearance between the rear handle and blade case, which makes gripping comfortable, even when wearing gloves. The rubberized hand grips improve control and reduce fatigue, which I appreciated during prolonged cutting sessions. Adjustments for depth and bevel are quick and smooth, thanks to large, accessible levers that can be operated one-handed.

Visibility is also a strong suit here. The wider space between the blade and housing offers a clear line of sight to the cut line and measurement scales. I noticed this made it much easier to stay precise without constantly stopping to check my work.

Power and Cutting Performance

This saw handles a wide range of materials with ease. From framing lumber to thick plywood and engineered wood products, it cuts cleanly and efficiently. That hypoid gear system really shines, offering more surface contact and power transfer than traditional worm-drive saws. The sealed oil bath gears mean the saw runs smoothly and quietly, with less wear and tear.

The included 24-tooth carbide-tipped blade is a beast in itself. Its ultra-coated surface reduces heat and pitch build-up, and the innovative “M” shaped teeth design slices cleanly through nail-embedded wood without chipping. Changing the blade is hassle-free thanks to the conveniently attached wrench.

Versatility and Applications

This model isn’t just a one-trick pony. It’s designed for framing walls, floors, and roofs, but also excels at plunge and bevel cuts thanks to its maximum bevel capacity of 51.5° and positive stops at 22.5° and 45°. I even tested it on some denser structural panels like OSB and particle board, and it performed admirably without bogging down.

The “sky hook” feature is a thoughtful touch for jobsite convenience, allowing the saw to hang from rafters or scaffolding without cluttering your workspace. This kind of detail highlights Makita’s attention to the needs of professional users who juggle multiple tasks on site.

Price Worthiness

The price tag on this saw positions it in the mid to upper range of circular saws, which might cause some hesitation. That said, considering the robust motor, hypoid gearing, and lightweight magnesium construction, it offers solid value for professionals who need a dependable, high-performance tool. Homeowners or casual users might find it a bit overkill, but for frequent use, this saw’s combination of power and durability justifies the investment.

Comparing it to other saws I’ve tested, this one strikes a smart balance between premium features and long-term reliability, which can translate into savings on repairs and downtime over time.

Product Comparisons

Among competing circular saws, the Makita 5377MG stands out for its hypoid gear system and oil bath technology, features not commonly found in many popular models from brands like DeWalt or Bosch. While DeWalt’s worm-drive saws are known for torque, they often require more maintenance and tend to be heavier. Bosch offers good ergonomic designs but doesn’t always match Makita’s cutting power or the ease of bevel adjustments.

This magnesium hypoid saw is lighter than many worm-drive competitors, which makes a noticeable difference during extended use. However, cordless circular saws from brands like Milwaukee offer greater portability, though they usually lag behind in raw power and cutting capacity compared to this corded model.

If maintenance-free operation and long-lasting power are priorities, this saw pulls ahead. But if you need the freedom of cordless cutting or a built-in dust collection system, you might want to explore alternatives.

Drawbacks to Consider

• The corded electric power source means you’ll need access to an outlet or generator, limiting where you can work freely.
• I found the saw slightly heavier than some magnesium competitors, though still lighter than steel-bodied options.
• The lack of onboard dust management meant I had to rely on external vacuums, which can be a hassle in some work environments.
• Some users with smaller hands might find the handle spacing a bit wide, impacting grip comfort.

Overall, while this saw excels in power and durability, the trade-offs mostly revolve around portability and some ergonomic preferences.

Positive Features

• Lightweight magnesium components reduce fatigue and improve handling
• Sealed oil bath gears provide maintenance-free, smooth operation
• Large cutting and bevel capacity with convenient positive stops
• Premium ultra-coated blade offers longevity and clean cuts
• Ergonomic design caters to gloved hands and prolonged use

Using this saw in real-world tasks, from framing to panel ripping, showed me that it’s a reliable partner for serious woodworking and construction jobs. The thoughtful engineering and premium materials make the Makita magnesium hypoid saw a professional-grade tool that balances power, precision, and comfort.
