The main secret: An engine that thinks for itself.
Inside this compact case lives not just a motor, but a high—tech brain and muscle in one bottle - a brushless motor with electronic switching (EC). The abbreviation EC (Electronically Commutated motor) is the key to understanding its magic. Let's decipher this spell.
Imagine an ordinary motor: it has brushes — these small carbon "paws" that constantly rub against the collector, switching the current in the windings and causing the rotor to spin. It's a mechanical, noisy and sparkling dance. The brushes wear out, friction creates energy losses and heating, and the motor itself becomes dull under load, sagging in speed.
And now — our hero, the EC engine. There are no brushes here. Generally. Instead of mechanical friction and sparks, a quiet and precise electronic controller. It's as if a supercomputer were installed at the control panel instead of a tired dispatcher manually switching the switches on the railway. This controller quickly "understands" the position of the rotor and switches the current in the stator windings (electronic switching) at the ideal moment.
What does this mean?
- Marathon runner's endurance: There are no rubbing brushes — there is nothing to wear out. Hence the fantastic resource, and the extended 5-year warranty. This motor is designed for a long life.
- Cool head (and body): The absence of friction and sparking losses means that the battery's energy is not wasted on heating, but is almost entirely used. The tool stays cool, and you get 30% more work on a single charge.
- Smart Power: Electronics don't just turn the motor, they control it subtly. Therefore, even when the drill meets resistance, the EC engine does not give up - it maintains high torque and stable RPM. No sagging, just steady, powerful work. The 75-90% efficiency speaks for itself: almost all of the battery's energy is converted into useful work, rather than heat and sound.
Simply put, EC is an evolution. The transition from mechanical labor to electronic intelligence inside your tool. He doesn't just spin, he calculates how to spin better, more efficiently, and for longer. And all these calculations are aimed at one goal: so that you, without being distracted by refueling and tool fatigue, conquer that very capricious wall.
Pose and grace: Why is he standing like a sturdy tin soldier?
Pay attention to the shape. The engine is positioned vertically here. This is not just a design move, it's a strategy. Such a "persistent soldier" hits from top to bottom with a greater amplitude than his "recumbent" counterparts. What does it mean? When it comes not to delicate drilling, but to real chiseling — demolishing old tiles, punching holes for wires, or fighting an octopus from rebar in the wall (oh, it seems like this is already a fantasy) — this hammer is fully invested in each blow. The impact energy of 2.2 Joules is not an abstract number. This is an impressive argument in the dispute "who owns the wall here". He confidently takes concrete up to 22 mm, drills metal up to 13 mm and, if necessary, wood up to 26 mm. A universal soldier, what can I say.
Comfort: For those who value their hands (and nerves).
Working with vibration is like riding in a cart on cobblestones all day. By the end of the day, your hands will fall off, and your mood will be lower than the baseboard you were just trying to nail down. There is also a built-in anti-vibration system (AVS or Anti-Vibration System). This is not a marketing dummy, but real springs and dampers inside that take over the impact. After an hour of work, you will not feel tired, but a little proud of the work you have done. And there is also a safety clutch. This is your personal bodyguard. If the drill suddenly comes across a surprise in the form of rebar and jams, the electronics will react faster than you can be scared and stop the tool. Your wrists will thank you. And yes, there is a soft start. The puncher does not jerk from its place like a frightened horse, but gains momentum smoothly and with dignity. This protects both your accuracy (the drill will not slip off the mark) and the "insides" of the tool itself.

The power is in the details, or the Small joys of a big deal.
Let's go through the tricks that turn work into pleasure:
- Illumination of the work area: When you get into a dark corner or under the sink, a small but fierce LED spotlight will illuminate your target. No more attempts to drill by touch.
- Reverse: Is the drill stuck? It doesn't matter! The reverse button, accessible even with gloves, will deftly turn it back on. It's like a time machine for drilling.
- Trigger speed control: A light tap — you start carefully. If you push harder, you get full power. Full control, just like in a racing simulator, only the prize is not the cup, but the perfect hole.
- SDS-plus cartridge: Changing the drill takes seconds. No keys, no magic. I inserted it, turned it on, and it's done. You spend your time working, not dancing with a tambourine around the rigging.
- Weight is only 2 kg (without battery): After the fifth hole at arm's length, you will appreciate this lightness. It does not pull down like a kettlebell, but floats obediently in your hands.
The heart of the system: Batteries that speak the language of Makita.
And here is one of the main trump cards. You are supplied with two batteries with a capacity of 4 Ah each. While one is working, the other is resting on charging from the included fast charger (2 hours — and back into battle). But the most delicious thing is compatibility with the Makita 18V LXT system. It's as if your phone is being charged by charging a friend, neighbor, and half of the gadgets in the office. The world opens up to you! If you or someone you know already has Makita tools on this platform, the batteries are interchangeable. You're not tied to a single brand, you're joining an entire ecosystem. And a voltage of 18 V (and at its peak, that's all 20-21 V) provides the most reliable power so that the tool does not "sag" under load.

Package contents: Not a "naked king", but a warrior ready for battle.
You are not just buying a "punch in a box". You are buying a ready-made solution. EVERYTHING is already in a sturdy case that can be stacked like a Lego:
- The hero himself is a puncher.
- His two loyal energy companions (AKB).
- A charging station for them.
- Depth gauge (in order not to drill through the wall into the neighbor's room, the relationship is more expensive).
- Side handle for particularly firm negotiations with the wall.
- The case itself has a base where every detail has its place.
This is not a complete set, this is a 007 agent kit from the repair world.
Who is this artifact intended for?
It is ideal for those who value time, nerves and results. For a home craftsman who is tired of compromises with a weak instrument. For a summer resident who needs both a house to put in order and a gazebo to assemble. For a novice foreman who wants to have his own reliable tool at hand. This is your passport to the league of people who are not afraid of DIY tasks. He will do all the rough, dusty, and power work for you: from mounting cornices and a TV to laying cables and installing sub-cabinets.
And remember, all the power and humor of this tool is backed up by serious things: certification for markets in several countries, a working network of service centers and instructions available on the website. It's not a one-time toy, it's an investment in your independence.
So if you're still standing in front of a wall with a nail and a hammer, ask yourself one question: "Isn't it time to call in heavy artillery?" BORT BHD-20Li-SR is not just a purchase. This is a declaration of war on all unfinished business in the house. And in this war, you now have the most reliable weapon. It remains only to begin.
