Masterforce Boost 20V cordless circular saw review | 5415.1

Masterforce upgrades brushless circular saw with a boost package

The cordless circular saw Masterforce Boost 20V hardly differs from its brushless predecessor. We decided to dive deeper and see what’s new and noteworthy about this updated model.


advantages

  • Brushless motor with boost upgrade
  • Gentle protective action
  • The base slides well over the material
  • Great performance for the price

disadvantage

Masterforce Boost cordless circular saw performance

The cordless circular saw Masterforce Boost drives a 7-1 / 4 ″ blade with its brushless motor. With an idle speed of 4800 rpm, this saw cuts smoothly and the blade leaves a surprisingly nice finish for a standard blade. The guardian action is nice and smooth too.

With more aggressive, fast cuts, you can feel the motor drop in speed under heavy load. It feels like the Pro-Class cordless circular saws from a few years ago. It’s perfectly capable of making the cut – even compound miter cuts aren’t a problem. It just won’t have that hot knife-through-butter feel that today’s premium saws have. However, it doesn’t have the same high dollar price tag either.

The maximum cutting capacity at 90º is 2-7 / 16 “- just under 2-12”, while at 45º you can cut up to 1-13 / 16 “. The bevel is maximum at 56º and a fold-out piece of plastic gives you a stop at 45º. This handles most of the popular cuts out there, so I have no complaints on the capacity front.

Boost upgrade

The boost upgrade for this saw is primarily an inside job. Rather than just using a brushless motor to improve the tool’s performance, run time and life, Boost completes the package with updated electronics and a smarter battery system.

When the tool detects a boost battery, it can get more power and increase performance. Compared to the brushless predecessor model, you will find similar performance with a standard battery and a little more confidence in the cut with a boost pack.

Design notes for Masterforce Boost cordless circular saws

The build

Masterforce sticks with metal components for the base, blade cover and blade protection. High quality saws often opt for plastic blade guards and I like that Masterforce avoids this temptation.

Workmanship of the Masterforce Boost 20V circular saw

On their brushed FlexPower model, the lever locks for the bevel and depth were made of plastic as opposed to metal. These levers were a bit more flexible than I prefer, so we’re pleased that this updated version has all-metal levers.

ergonomics

The general design of this Blade-Right Sidewinder isn’t crazy. The two handles are in line and the second handle has enough circumference to provide a secure hold when you have larger hands or are wearing gloves. A simple pressure with the thumb releases the lock.

height and weight

As a mere tool, the Masterforce Boost cordless brushless circular saw weighs 7.8 pounds and 8.8 pounds with a 2.5 Ah Boost battery. We didn’t have a 5.0Ah boost battery to test, but expect the weight to add another 1/2 pound or so with the higher capacity.

Overall, they managed to reduce the weight a bit when compared to the FlexPower model, but it’s still on par with Pro saws that come with the same type of metal construction.


Blade change

Blade changes are pretty standard, though Masterforce adds a modern twist with its flat motor housing. This allows you to place the saw on the motor housing for more convenient replacement.

Additional functions

  • Electric brake
  • LED light has a pre- and post-glow
  • Strong rafter hook

Masterforce Boost cordless circular saw price

The regular price for this saw is $ 159.99 as a tool only and there are no kit options available at the moment. However, if you’re on the Menards mail-in discount train, we’ve seen it at just $ 142.39. The Boost upgrade costs just $ 10 more than the standard brushless circular saw.

There’s also a 6 1/2 inch version that has the Boost upgrade too. It costs $ 119.99 as a tool only if you’re looking for something lighter and more compact.

The bottom line

The Masterforce Boost circular saw sits quietly in a favorable position with no major competition as a brushless 7-1 / 4 “model in the price range under $ 200. It doesn’t really “wow” us like some of the ultra-premium models do, but it doesn’t disappoint either. It has a solid design and a range of features to match the performance we saw from the top Pro models just a few years ago.
