Final Thoughts

The Masterforce Brushless Impact Driver fits well in the group of Prosumer models bridging the gap between DIY and professional use. It's bulkier than the premium brands and drives on the slow side but overcomes that with some of the highest measurable torque we've seen so far. Combined with an excellent feature set at this price point, this competes very well against Craftsman, Kobalt, Ryobi, and Skil. It's a good choice for any serious DIYer and has the performance to be an entry-level Pro consideration where Menards has a market presence.

Masterforce Brushless Impact Driver Stands with Other Chervon Brands as Heavy Hitters

Masterforce is a name you’re familiar with if you live in areas that Menard’s serves. Our peaceful corner of central Florida doesn’t, so it’s a treat to get our hands on the Masterforce Brushless Impact Driver to see how it does against other 18V/20V max competition.

Pros

  • Top-tier measurable torque
  • Brushless motor has 3 speed modes plus auto-stop assist
  • Outstanding LED halo
  • One-hand bit insertion
  • Spring-loaded bit ejection

Cons

  • One of the slower models we’ve tested
  • Relatively bulky footprint compared to other 18V/20V max models

Performance

Every manufacturer has to decide how to balance their energy between speed and torque in an impact driver. Masterforce chooses to give up some speed to hit harder.

 

On paper, its 2800 max RPM and 3500 IPM is plenty to drive screws effectively. Its 1700 in-lbs of torque is well within our Pro expectation, though it looks modest against models that exceed 2000 in-lbs.

The Masterforce Brushless Impact Driver suffers a bit in speed under load. Averaging 358 RPM while driving a 1/4″ ledger screw, only Skil drives slower. While it’s slow, the motor doesn’t struggle to drive it. It won’t have any issues driving ledger screws and timber screws on a regular basis.

Masterforce Impact DriverTorque is where Masterforce shows off its muscle. In our tests, it slammed an average of 2647 in-lbs – just 9 in-lbs shy of Milwaukee’s M18 Fuel sitting at the top.

It has impressive breaking torque as well. It consistently breaks 3900 in-lbs on our rig, good enough for 2nd place behind Skil and just above Kobalt’s 24V model.

Two things stand out here. First, names like Makita, Milwaukee, DeWalt, and others are behind Masterforce in this category. Second, the top 3 nut-busters are all brands that Chervon manufacturers. Despite their somewhat modest torque specs, the design team is clearly making a hammer/anvil mechanism that’s hitting harder than brands claiming much higher torque.

Size and Weight

As we leave the premium brands to head closer to the Prosumer and DIY classes, we expect to get more weight and bulk. At 2.8 pounds bare and 3.8 pounds with a battery, Masterforce is in the heavier half of 18V/20V max models, but it’s not unreasonable.

Masterforce Impact Driver

The head has some girth to it and it’s on the longer side at 5.9″. It’s also the tallest model in its class at 8.3″. Unless you find yourself in a tight spot frequently, it’s not an unwieldy design.

Feature Set

Brushless Motor

Masterforce goes with a brushless motor on this model. Expect better runtime, power, and service life over brushed models.

Modes

You get a nice control set for an impact driver at this price point. A blister button lets you select between 3 standard modes and an auto-stop. The auto-stop mode senses when the tool begins to impact and stops to avoid over-torquing screws or bolts. Here’s how the standard speeds break down:

  • Speed: 0 – 1100/0 – 1900/0 – 2800 RPM
  • Impact Rate: 0 – 200/0 – 2350/0 – 3300 IPM
  • Torque: 770/1240/1700 in-lbs

LED Halo

You can see the Chervon influence here as the LED halo that’s also on Skil’s 12V brushless impact driver makes an appearance. A 3-LED light ring does a great job, but this style even out the light even better for work in low-light conditions.

Bit Insertion and Ejection

You get both one-hand bit insertion and spring-loaded bit ejection with this model. It’s not something everyone does, but it’s really handy on the jobsite.

Pricing

At the time of writing, the Masterforce Brushless Impact Driver kit runs $159.31 with a $20 discount and an 11% mail-in store credit rebate (retailers still do that?). So what else can you get in the $150 – $200 range? We’ll toss the extra 11% since that sale is about to end.

That’s a pretty good smattering of impacts that fill the gap between DIY and Pro with DeWalt also sneaking under the $200 mark.
