Review Summary

If you’re looking for a circular saw to put others to shame, then you’ll want to take a closer look at the Makita 5377MG. This is no standard circular saw. This is a magnesium hypoid saw, offering outrageous amounts of power and a build-quality that’s second to none. It’s a pretty hefty tool with substantial size to it, but magnesium parts keep the weight down. Even though it’s bulky for a circular saw, it’s light compared to worm drive saws and even other hypoid saws.

There’s a lot to like about this machine. It’s got integrated oil bath technology for a low-maintenance experience. Its 15-amp motor paired with hypoid gears means that it’s a pleasure to use as it cuts through practically any material like a hot knife through butter. Its high price means that many hobbyists will look past it.

Steel Hypoid Gears

Hypoid saws are the heavy-duty monsters of the circular saw world. They’re like chainsaws in circular saw clothing, offering far more power and durability than a standard circular saw. The Makita 5377MG is a hypoid saw, so it’s got gobs of torque and can power through just about anything. What makes this tool particularly durable is that the hypoid gears are all crafted out of steel, providing an incredible level of durability. This might be the last saw you ever need to purchase.

It’s Pretty Bulky and Heavy

If you compare the 5377MG to other hypoid or worm drive circular saws, you won’t think that it’s a very heavy model. It compares favorably to similar saws. But compared to a regular circular saw, the 13.2 pounds that this saw weighs seems practically obese. If you’re used to using a circular saw one-handed, you’ll have to change gears and get used to using two. Not only is this a heavy and large saw, making it more difficult to manage, but its substantial power means a second hand is necessary to keep it steady.

Made with Magnesium Components

Magnesium is an incredibly strong metal that’s also lightweight. Many of the components on this saw are crafted from magnesium, in order to keep the weight down. Granted, it’s still a burly saw, but that’s due to the hypoid gearing. You can’t get this kind of torque and power from a tiny saw, but with magnesium components, it’s as light as it could possibly be.

Oil Bath Means Maintenance-Free

Worm drive saws require regular oil changes and maintenance. But this hypoid saw features oil bath technology. This means it has a sealed gear housing and never needs oil changes. You won’t have to maintain this machine, but you’ll still get incredible performance that’s superior even to worm-drive circular saws.
