If you’ve shopped for cordless power tools lately, you’ve heard the buzz about brushless motors. But what makes them so superior? The Dewalt 20V Max XR Impact Driver Kit DCF887M2 is a perfect example of brushless motor dominance in action. It runs cooler, delivers more torque, and lasts longer per charge than any brushed competitor. This article dives deep into the technology, compares real-world performance, and shows why upgrading to brushless is a smarter investment.
Brushless motors replace the mechanical brushes found in traditional motors with an electronic controller. That simple swap eliminates friction, reduces heat, and boosts efficiency by up to 50%. For professionals and DIYers alike, that means more work done, fewer battery swaps, and longer tool life. Let’s break down the engineering and see how the DCF887M2—and other top brushless tools—stand apart.
What Makes Brushless Motors Run Cooler?
Heat is the enemy of any motor. In brushed motors, carbon brushes drag against the commutator, creating sparks and heat. That wasted energy drains your battery and wears out the tool. A brushless motor, like the one in the DEWALT 20V MAX Cordless Drill Driver Set DCD777D1, uses magnets and an electronic circuit to spin the rotor without physical contact. No sparks, no friction, less heat.
Less heat means you can push the tool harder for longer. The Dewalt 20V Max XR Impact Driver DCF887M2 stays cool even during heavy-duty fastening. That thermal efficiency also protects the battery, preventing the thermal shutdowns that plague brushed tools. So you keep working—not waiting for a cooldown.
Faster Speeds and More Torque
Brushless motors deliver more power per unit of energy. The electronic controller can adjust the magnetic field in real time, optimising torque and speed for the task. For an impact driver like the DCF887M2, that translates to up to 1,825 in-lbs of torque and 3,200 RPM. Brushed rivals simply can’t match those numbers without overheating.
Consider the DEWALT 20V MAX XR Oscillating Multi-Tool DCS356B. Its brushless motor delivers up to 20,000 OPM with variable speed control. That’s the kind of precision and power you only get when you ditch brushes. For impact driving, the DCF887M2’s three-speed settings let you match the power to the screw or bolt, preventing stripping while maximising speed.
Longer Runtime – More Work Per Charge
Battery runtime is the holy grail of cordless tools. A brushless motor converts up to 85% of electrical energy into mechanical work. A brushed motor manages only 60-70%. That difference means you can sink twice as many screws on a single 5Ah battery with the DCF887M2 compared to a brushed impact driver.
The same efficiency boost appears in other brushless tools. The DEWALT 20V MAX Cordless Drill and Impact Driver 2-Tool Combo Kit DCK277D2 pairs two brushless tools with two 2Ah batteries. Users report completing full deck builds without recharging. That’s the practical magic of brushless dominance.
Comparison of Top Brushless Cordless Tools
To help you see the value, here’s a comparison of several brushless tools from the DEWALT and Dremel families. Each offers cooler operation, faster speeds, and longer runtime than brushed equivalents.

The table above highlights that brushless motors aren’t just for impact drivers. Rotary tools, oscillating multitools, and combo kits all benefit from the same technology. The Dremel 8250-5 (12V brushless) and the DEWALT DCS334B Jig Saw are other excellent examples—each running cooler and longer than their brushed predecessors.
Beyond Drills: Brushless in Other Tool Categories
Brushless motor dominance extends far beyond drills and impact drivers. Outdoor power tools are also going brushless for the same reasons: efficiency, runtime, and durability.
Take the Cordless Power 1450PSI Brushless Pressure Washer. With a perfect 5-star rating and a price of $99.99, it delivers impressive cleaning power without the noise and heat of a brushed motor. The battery lasts for multiple car washes on a single charge.
For yard work, the 2-in-1 Cordless Pole Saw (Brushless Mini Chainsaw) offers a 21V brushless motor that handles branches up to 6 inches thick. It includes two batteries and a 13.5-foot reach. While its rating is lower (3.2 stars), it still demonstrates how brushless technology is becoming standard even in budget-friendly tools.
Reliability and Tool Life: No Brushes to Replace
Brushed motors wear out. The carbon brushes gradually erode, causing power loss and eventual failure. Replacing brushes is a hassle, and often the tool is discarded. Brushless motors have no such weak point. The electronic controller handles commutation flawlessly for thousands of hours.
DEWALT backs its brushless tools with solid warranties. The DEWALT 20V MAX XR Oscillating Multi-Tool DCS356C1 (kit version with battery and charger) has over 17,800 reviews and a 4.8 rating. That’s the confidence of real users who rely on these tools daily.

FAQ – Brushless Motor Dominance
What is a brushless motor in power tools?
A brushless motor uses an electronic controller to energise the stator windings, eliminating physical brushes. This reduces friction, heat, and wear while improving efficiency and torque.
How much longer does a brushless battery last compared to brushed?
On average, brushless tools deliver 30-50% more runtime per battery charge. For heavy-use tasks like driving screws or cutting, the difference can be even greater.
Is the Dewalt 20V Max XR Impact Driver DCF887M2 brushless?
Yes, the DCF887M2 features a brushless motor that runs cooler, faster, and longer than brushed impact drivers. It produces up to 1,825 in-lbs of torque and has three speed settings for precision.
Are brushless tools worth the higher upfront cost?
Absolutely. The savings from longer battery life, less downtime, and increased tool longevity offset the initial price. Most professionals recoup the cost within weeks.
Can I use old brushed batteries with new brushless tools?
It depends on the brand. DEWALT 20V MAX batteries are cross-compatible, but performance is optimised when using high-capacity batteries like the 5Ah or 6Ah power packs.
