Power / Performance

Milwaukee 2631-20 Power

Cordless circular saws of today are certainly better in terms of power and performance than they used to be at one point. The former, as in the case of this Milwaukee 2631-20 M18 Brushless 7/1/4” Circular Saw, is well-equipped to handle daily applications. Such as cutting heavy sheets, framing lumber, etc. No doubt, it makes a HUGE impact in the power tool category.

The benefit this particular model has over others is that it features a brushless motor, unlike standard circular saws with a traditional brushed motor. And the outcome of that takes the form of abundant power (speed of 5,800 RPM) for the toughest of materials (for example, engineered lumber).

The cuts are very strong and quick with the least amount of drag. The brand supplies the standard OEM blade as well as special white blades that cut way smoother and faster.

In case you happen to use the new 12 Ah batteries with this Milwaukee circular saw, expect the power capacity to be pretty much the same as that with 15-amp circular saws. Needless to say, performance does indeed suffer a bit when the tool is paired with a smaller battery. So it’s best to use the 12 Ah battery for taking full advantage here.

Other performance-related characteristics include the built-in dust blower. What this does is gives you a clear line of sight. Even the dust chute on the side keeps dust away and out during the cutting operation. Although some dust gets left behind, literally behind the unit, which can be a nuisance to dust off all the time.

Build Quality

Milwaukee 2631-20 Build Quality

Did you know that the original version of M18 was the brand’s very first cordless circular saw (2014) with a brushless motor? So it’s only natural to assume that the design has been subjected to multiple changes in terms of features and build quality.

The current M18 Brushless 7-1/4” Circular Saw by Milwaukee has been upgraded. The simplest, most basic proof is the integrated rafter hook that allows you to hang it onto something close by during work. Then there’s the inclusion of LED lights for illuminating the cutting line when starting the cuts (unfortunately, there’s no cutting path illumination).

The brand has definitely not neglected the quality aspect because this circular saw is super-strong with lightweight yet robust blade guards and magnesium shoe. No trace of cheap-quality plastic or metal at all.

The shoe paves the way for bevelling up to 50 degrees. Then lock that into place at the bevel angle of your choice. On the downside, there aren’t any positive angle stops, such as 45 degrees.

This magnesium shoe also features a knob and slot. The slot is for the rip fence guide while the knob is for tightening the fence guide. Obviously, the rip fence guide you have to purchase separately.

What’s also a part of the product is the hex key, so you can swap blades. Built-in key storage is also a pretty convenient design feature here. And so is the handle of this power tool, which has a fine-textured, hefty rubber grip.

As for the trigger, it gets activated on the activation of the thumb safety button. And the thumb safety button is installed on both sides of the rubber over-mold grip, which is great news for both left-handed and right-handed users.

The blade, however, is on the right side, thus not the best for right-hand orientation. But then most right-handed users are already well accustomed to this since it is, after all, traditionally built.

Size and Weight

Undoubtedly, this is an extremely portable cordless circular saw that weighs just a little over 7 pounds. Despite the lightweight and portability benefits, the power tool is the best for tough applications. Such as working on scaffolding and roofs, overhead cutting, and the like.

Compared to heavier corded circular saws, which generally weigh between 10 and 14 pounds, this cordless version is nothing but a welcoming attribute. Especially when your jobs require you to work up high. So you can be more productive while also ensuring complete safety during your daily work.

And don’t be mistaken just because the weight and size are compact. Because this doesn’t necessarily mean that it isn’t a full-sized circular saw. After all, the blade included is 7-1/4”, right? At the same time, this is no special size or anything like that. And that’s amazing because “special” blades are a little annoying and difficult to find in the case of replacement.

Run Time

The runtime of the circular saw is no longer a hurdle, despite the Milwaukee M18 being a cordless circular saw. When you pair it up with 12.0 Ah batteries, the runtime is quite impressive. So you’re looking at making as many as 600 cuts (2×4) on a single charge. That gives you 50 cuts approximately per Ah (amp-hour).

The time when cordless tools were criticized for their short, crappy runtime has surely passed. With M18, even the charging time of the battery is nothing to complain about (just 60 minutes for a full charge).
