PTR Review
  • Overall Rating 8.0

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.

Overall Score 8.0 (out of 10)

Masterforce Gives Their Brushless Impact Driver a Boost Upgrade

Masterforce is a brand you may not have on your radar, but it’s definitely not one to ignore. The Masterforce Boost 20V cordless impact driver is priced to compete on the same level with popular Prosumer brands such as Ryobi, Craftsman, and Skil. We ran it through a series of tests to see how the Boost upgrade compares in this competitive class.


  • LED halo (LOVE this!)
  • Brushless motor with Boost upgrade
  • 3 electronic speeds plus auto-mode
  • One-handed bit change


  • On the heavy side
  • A bit more heat build up than other models on tougher drives

Masterforce Boost 20V Cordless Impact Driver Performance

Making an Impact

Overall, we enjoyed the improved performance of this impact driver compared to its previous version. Even though both are brushless, the Boost model boasts higher specs across the board: 3100 RPM top speed, 3500 max IPM, and 2000 in-lbs of torque.

We tested it in both drilling and driving applications. On the drilling side, we easily powered through 2x using a 1/2-inch twist bit as well as a 3/4-inch spade bit, essentially converting our rather expensive lumber to swiss cheese. Impact drivers still aren’t the go-to for all drilling applications, so we still recommend getting the combo kit that includes the Boost hammer drill. However, this impact driver can handle a lot of your drilling needs if you want just one tool.

Turning our attention to driving capabilities, it unsurprisingly handled small screws and 3-inch lag bolts without any difficulty. If anything, its wider size may get in your way slightly during precision fastening, but it doesn’t have any issues driving even big screws.

While power isn’t an issue, it is slower on tough applications compared to other Prosumer competition. In our RSS Test (8-inch rugged structural screws into stacked OSB subfloor), it was able to fully drive them in an average of roughly 20 seconds.

During this test, we also noticed the heat picking up more than other models we ran through the same test. That’s not unusual when you’re driving long screws and the tool didn’t hit thermal shutdown on us. Just know that it’s a possibility when you’re working on tougher applications.


You control this impact driver with three electronic speed settings and an auto-stop mode paired with a typical variable speed trigger. When you engage the auto-stop mode it will automatically stop rotation 1-2 seconds after the impacts begin. It’s useful when you need to prevent overdriving that causes damage to your material or fasteners.

I wanted to test how effective the assist mode really is when driving fasteners. We laid out a piece of pine 2×4 and proceeded to drive some drywall screws on the highest speed setting. It felt like the impact driver was going to send it all the way through the board. That’s exactly what we expect when we pair soft wood with small screws.

Next, I turned on the assist mode while still set to level 3 and the difference was night and day. The rotation stopped about one second after impacts began and left me with a perfectly countersunk screw.

Masterforce Cordless Impact Driver Design Notes

LED Worklight

There seems to be some debate in the tool universe concerning the optimal placement for an LED work light. Should it go under the chuck? On the foot? Maybe the side? Like their previous model, there’s an LED halo surrounding the collet and it’s one of the best designs we’ve seen. Say bye-bye to annoying shadows!

The tool feels very robust in a well-built sort of way. The grip favors larger hands and the rubber over-molded grip offers substantial grip even if you’re not wearing gloves or it’s a particularly hot day and your hands are sweaty.

As far as size is concerned, Masterforce’s design is a bit on the larger side. However, it remains very well-balanced, unlike some impact drivers which can feel a little lop-sided when you insert a battery.

Overall, you’re looking at 2.8 pounds for the bare tool and 3.9 pounds when you add a 2.5Ah Boost battery. From front to back, it’s 5 7/8 inches long.

Masterforce is exclusively available at Menards and the bare tool runs $99.99. It’s $149.99 with a 2.5Ah Boost battery, charger, and stackable hard case. Keep your eyes peeled because Menards often runs mail-in rebate and sale promotions so you just might snag it at a discount. This impact driver also carries a 3-year limited warranty and 90-day return policy.

If the 2-piece Boost combo is more your speed, that kit runs $269.99 with a couple of 2.5Ah Boost batteries, charger, and soft bag.

The Bottom Line

Masterforce’s Boost upgrade to their brushless impact driver resulted in extra power and speed that takes the tool up a notch. Even though it’s still on the bulkier side of the Prosumer class and a bit slower, its sub-$150 kit price tag is pretty attractive if you’re looking for better performance than pure DIY models without the cost of a premium brand.
