Makita BTD140 LXT 18-Volt Lithium Ion Impact Driver Kit Review
Makita BTD140 LXT 18-Volt Lithium Ion Impact Driver Kit Feature
- LXT Lithium-Ion battery and optimum charging system produces 280% more lifetime work with 2x more cycles.
- Makita built 4-pole maximum torque motor delivers 1,280 in. lbs. of efficient torque in a compact size.
- 50% more compact design at only 5-3/4" long and weighs only 3.3 lbs. for less operator fatigue
- LXT Lithium-Ion provides longer run time, 5x lower self-discharge (for use any time) and 16 firm holding contact terminals (for constant high power)
- Makita's proprietary hammer and anvil are made using the highest quality steel and heat hardened to last longer.
But perhaps the coolest innovation is what Makita calls its 45-minute Optimum Charger. It actually talks to the batteries it charges throughout the cycle, using a built-in memory chip in the battery and, believe it or not, a CPU chip in the charger itself, which analyzes the data stored in the battery chip to decide on the best charging method at that time.
Slide one of these batteries onto the supremely designed impact driver and you’ll be amazed at what you can do. Despite its size (for the record, it’s 5-3/4 inches long and weighs barely 3 pounds), this driver kicks out an unbelievable 1,280 in./lbs. of efficient torque, a no-load speed of 2,300 rpm and 3,200 blows per minute, putting it way out in front of the pack. We really like the integrated worklight, too. It illuminates as soon as you pull the trigger, and it stays on for 10 seconds or so after you release the trigger, too – a handy little feature.
Makita’s always made ergonomically positive tools that feel good in your hand and take the strain off your body, and this one’s no exception. The slightly curved grip is so comfortable, and because it’s super compact and lightweight, this driver’s an absolute pleasure to run. -- Kris Jensen-Van Heste
What’s in the Box
Impact driver, two LXT Lithium-Ion 3.0Ah batteries, 45-minute optimum charger, tool case
We've come a long way from sweat and a screwdriver. A hundred years ago, builders would never have envisioned a tool as powerful and efficient as this one. Heck, even 20 years ago. Science has ushered battery technology along, and the LXT Lithium-Ion system that powers this impact driver has a ton of advantages over standard NiMH or NiCad batteries. The Lithium-Ion technology means 1,400 battery life cycles, longer run time, lighter weight, a great reduction in the self-discharge rate and built-in shock-absorbing features to protect your battery. But perhaps the coolest innovation is what Makita calls its 45-minute Optimum Charger.
