Milwaukee 6477-20 Review Summary:

You may not have heard about the Milwaukee brand, but you can rest assured that they manufacture some of the best power tools within the affordable price category. They offer great units both for hobbyists and professionals. In fact, some professionals who don’t care much about the sheer branding usually favor this in comparison to some other well-known companies. The reason is quite simple – you don’t have to pay for the brand in this case.

Overpaying is a common issue with many consumers, especially the ones that don’t know what to look for. In simpler words, a lot of people end up purchasing the thing that seems good enough but in reality – it’s not. Consequently, they end up with an expensive power tool that isn’t capable of fulfilling one’s expectations for the money. If you’re tired of strolling on the Internet and reading hundreds of biased reviews, take a moment and check this one out. We try to stay as objective as possible so that you know exactly what to expect if you ever opt to invest in these machines.

Milwaukee 6477 – The Basics

If you’ve been looking for a decent worm drive saw, this one looks like a good solution. It may not be the best model on the market, but it definitely has a thing or two to offer. While the professionals do like its features, some of them are lacking. However, the DIY enthusiasts love the affordability and versatility, which are two of the most notable advantages.

One thing this model doesn’t lack is power. The 15-amp motor is able to deliver up to 4400 RPM meaning it will rip through wood like a hot knife through butter. On top of that, its magnesium construction offers a great deal of stability and reliability. One thing you don’t have to worry about is downtime.

The Features

The design

The ergonomic aspect of this machine is tolerable but not impressive. Even though it’s a pretty standard design, we would have liked to see more dedication to some parts of it, especially the hand grips. The grips are made of hard plastic and seemingly cushioned with rubber. However, the buffers don’t do much when it comes to the reduction of vibrations. Therefore, we recommend wearing work gloves at all times to eliminate some of those vibrations. As you can tell, it’s not foreseen for 24/7 use, but it does its job quite well, as long as you maintain it in good condition.

The shoe is made of heavy-duty metals meaning it won’t bend, warp, or kick. The casing, on the other hand, is made of durable magnesium and hard plastic. When it comes to endurance, the Milwaukee 6477 model can be regarded as trustworthy but not as resistant as some other units from the same price category.

Safety and maintenance

The safety is at a satisfactory level. One cannot say there are a ton of safety precautions, but there are more than enough to keep you as protected as possible. The exclusive oil site glass allows you to gauge current oil levels within a few seconds. It’s an important feature for maintaining the machine in good condition because you don’t have to hassle with additional tools in order to break the unit apart and reach the oil reservoir.

As far as the proper maintenance goes, everything is written in the user manual. All you have to do is follow the instructions, and the saw should last for years.

Tends to vibrate

Things we liked about it

Durability and ease of use are the two main elements we liked about this product. It’s one of the simplest ones around, and it doesn’t require any previous experience. It might need some adjusting out of the box, but it takes only a couple of minutes to do it.

As far as the durability goes, the combination of steel and magnesium makes this model resistant to many outside factors such as hits, drops, and more. As we already said, the shoe is made of heavy-duty alloys which guarantee a long life. On top of these advantages, they also offer a 5-year warranty so that you can replace the unit if anything goes wrong within five years.


Things we didn’t like

The hand grips aren’t its strongest points, to say the least. Even though they are rubberized, the amount of vibrations can be a burden to some people, especially the ones that aren’t working with these tools on a daily basis. However, the work gloves are the simplest and cheapest solution for this problem.

Apart from the hand grip problem, many people don’t like the country of origin. It may play a role in some people’s decisions, but you can rest assured that Milwaukee takes great care of their products, even if they are assembled on the Asian market. The quality control department is good, and their customer support is more than willing to help at any time.

What Users Say About The Milwaukee 6477-20

We’ve stumbled upon hundreds of user reviews all over the Internet. Some of them praise the smoothness of operation and ease of use, while the others complain about the amount of hard plastic included in the design. Even though the opinions are quite mixed, positive ones prevail. Therefore, as far as we are concerned, it’s a worthy investment for most DIY enthusiasts and even some professionals.

This unit is far from being the best possible solution for every artisan. However, the ones that are looking for specific features, good ergonomics, and a great price can find some good use in this particular unit. The key is in getting the most of it for the best price. As we said, it will do the job well, but it won’t perform any miracles.

If you’re looking for a heavy-duty piece of equipment, skip this particular model because it probably won’t be able to cope with massive projects. On the other hand, if you need a good substitution for your old circular saw, don’t hesitate to give it a try.
