Includes 18V Cordless LXT Lithium-Ion Hybrid™ 4-Function Impact Driver - BTP140, (2) 18 Volt 3.0 Ah LXT Lithium-Ion Batteries - 194205-3, Optimum Charger - DC18SC, Tool Case - 824753-5, Operating ManualThe best of both cordless worlds. Need the power of an impact driver, but also a hammer drill? Look no further than the Makita BTP140. Now you can drill a hole in masonry materials, and then drive a screw with the same tool by simply adding an anchor. This all-in-one drill has great ergonomics with comfortable rubber grips and is at least one pound lighter than most standard hammer drills.
The hybrid has the highly efficient Makita-built 4-pole motor with dual steel ball bearings. It has 1,240 in./lbs. of torque in impact mode and 2,300 to 27,600 blows per minute in hammer mode. This hybrid drill also has the best belt clip on the market today. The clip doesn't rotate like it does on other brands, making it hard to remove. The drill stays in place in pants pockets, belts and tool belts with this heavy-duty steel belt clip. It can easily be relocated to the opposite side of the drill for lefties.
Located just above the trigger are two "headlights." Headlights refer to small LED lights that provide light where you need it most. I was skeptical about this feature, thinking it was just another gimmick, but after using it for some time, I've come to depend on it. From lighting my way to the house in the dark, when bringing the batteries/tools on cold nights to providing light in a dark cabinet, closet, or under a desk; this a must-have feature. There's also a glow-in-the-dark ring around the nose piece that makes the drill easier to locate in darkened spaces.
Another great feature on this tool is the all-metal, quick-change, hex, Insty bit chuck. The chuck only accepts drill bits and driver bits that have a hex shank at the opposite end of, for example, a #2 Phillips driver bit. This really speeds up bit changes. Hex Insty bits have really become the standard and are offered in every drill bit kit available. There is an accessory Makita chuck that converts the quick change, hex bit chuck into the older style 3-jaw chuck which will accept round shank drill bits, so you can use your existing bits.
Rubber grips adorn the exterior of this tool and protect it during impact if it falls. This kit comes with 2 batteries, charger and a cool case with convenient bit, screw and oddity storage on top.
The Benefits of Lithium-Ion
Lithium-Ion tools have more power with less weight. They have more power than a regular 18-volt tool because each battery cell within the battery pack has more juice than a standard battery and can deliver more power to the tool. These tools are also as light as a 12-volt tool because lithium is lighter than the nickel and cadmium in standard battery packs. 18-volt lithium-ion tools have the best power-to-weight ratio of any cordless tool. These tools come with the slide-in battery system and have more contact area than other tools. This means that more battery power will be transferred at a faster rate. I've seen other cordless tools with 2 small contacts and even worse, with loose connections. A tool with loose connections will not perform as advertised and may even cause premature death of the battery.
Battery Charging System
This Makita tool also has the most advanced charging system available. Generically, it's called a "smart charging system." A computer chip inside the battery lets the charger know exactly how to optimally charge the battery, to completely charge each cell within the battery and for maximum battery life. Each battery is made up of smaller 1.2-volt cells. Often a battery will drain unevenly during normal use, at different rates within these internal cells. A normal charger will stop charging the battery when one cell reaches maximum capacity, not all of them. Once this happens once, it will continue to do so as long as you use the battery. What this means is your 18-volt battery is now a 16- or 17-volt battery and it can drop even lower. A "smart charger" will charge every cell independently until each cell is fully charged, so your 18 volt battery will remain 18 volts for its entire life. This charger has a fan in it and blows air through the battery to cool it down before charging so the battery can be charged right away, unlike other brands, where the charger waits until the battery cools, or even worse attempts to charge a hot battery pack and damages it or decreases the life of the battery. These Makita lithium-ion batteries will last 280 percent longer than standard batteries and can be charged over 1400 times, as opposed to the standard of 600 to 800 times, which alone can justify the higher price tag. These slide-in batteries are 3.0 amp-hr batteries; they will provide power to the tool longer than standard 2.0 Amp-hour batteries. The higher the amp-hr rating, the longer the battery will last before it needs to be recharged. For light-duty applications, these batteries will last all day or even several days before recharging. I leave my charger at home when doing small jobs, because I know I don't need it. The charge stays in the battery without dissipating during non-use and there is so much power in these batteries, I know I'll have enough juice to complete a job. For heavy-duty applications, bring the charger with you just in case. --Gabriel Shantara Ford
