October 1, 2007 – La Mirada, CA  Makita USA, Inc., manufacturer of high quality industrial power tools and accessories, is proud to announce the release of its new 18V LXT Lithium-Ion Cordless ½” Impact Wrench Kit, model BTW450. The new impact wrench packs 325 foot-pounds of torque created by 2,200 rotational impacts per minute, and is designed for a wide range of applications including steel beam construction, telephone pole installation, automotive, mudsills, and more.  

“This tool is the most powerful Lithium-Ion powered cordless impact wrench in its class,” said Brad Wheeler, Makita product manager. “With this much power in a cordless model, it makes perfect sense to go cordless for tough impact driver applications.”
The BTW450 is a powerful and convenient substitute for air-powered and AC wrenches. The Makita-built 2-Pole Motor delivers a top no-load speed of 1,600 RPM. The patented Makita hammer/anvil design is durable and longer lasting. The BTW450 has a ½” square drive round head detent pin standard (flat pin is optional) for a range of applications. 
The tool has an ergonomic grip and large rocker trigger switch for easier operation, and a single L.E.D. light to illuminate the work area. The design also features a jobsite-tested shock-absorbent handle to protect the battery. At 10.5” long and 7.5 pounds, the BTW450 provides superior balance and control.
The BTW450 is ideal for steel contractors, commercial contractors, automotive line assemblymen, residential contractors, and HVAC contractors. It can be used for: steel beam construction; I-beam construction; utility pole, telephone and cell phone pole installation; overhead door installation; mudsills; automotive work; conveyor systems; HVAC, fire sprinklers; oil fields and refineries; anchors; tilt-up construction; and more.
“Makita has been the market leader in cordless impact products since their US release in 1988,” said Brent Withey, marketing brand manager. “The BTW450 is the latest in a long line of Makita impact products built with best-in-class engineering.” 
The BTW450 is powered by Makita’s 18V LXT Lithium-Ion battery technology, a breakthrough in cordless that produces 280% total lifetime work with two- to three-times more cycles. The kit includes a Rapid Optimum Charger, which charges a Makita 3.0Ah Lithium-Ion battery two-times faster in only 25 minutes. To achieve maximum efficiency, the Rapid Optimum Charger
and battery communicate throughout the charging process using the built-in chip in the battery and built-in CPU chip in the charger. The charger also uses “Active 3 Control” for current control, thermal control and voltage control, with a built-in fan to cool the battery, extending the life of the product and producing more lifetime work. Makita’s Rapid Optimum Charger carries the Energy Star label for its efficient charging process.
Model BTW450 is a kit that includes the tool, tool hook and screw, two 18 volt LXT Lithium-Ion batteries (3.0Ah), one Rapid Optimum Charger, a contractor bag, and battery cover. Model BTW450Z includes the tool only.

Makita’s 18V LXT Lithium-Ion Cordless Tool Series
Since its introduction on October 3, 2005, Makita’s LXT Series featuring 18V Lithium-Ion Battery Technology has been providing the professional end-user with more work solutions. The 18V Lithium-Ion battery is a breakthrough in cordless with more power, less weight and better engineering, and Makita is proud to be the first to bring it to jobsites across America.
"Makita did not just design a longer run time battery; we designed a complete tool solution to redefine the way pro users work,” said Ken Hefley, senior vice president marketing, Makita USA. “The LXT solution is all muscle and no fat, with 18V Power at 12V Weight.  LXT allows the pro user to work longer with a better engineered tool solution."
Makita\'s new LXT Series has been designed specifically for Lithium-Ion technology with less weight in a more compact size. LXT is 40% less weight and more compact. The better fit ergonomic shape fits like a glove with even pressure while adding more control.  The LXT series also come equipped with built-in high impact L.E.D. lights that operate independently from the tool to illuminate the work area.
Makita LXT Lithium-Ion Batteries and Optimum Charging System produces 280% total lifetime work with 2-3x more battery cycles than the traditional Ni-Cd batteries.  Makita\'s LXT Lithium-ion batteries provide the pro user with many benefits, including 1,400 battery life cycles, longer run time, weighs 40% less, 5x lower self-discharge to keep cells active and ready to use any time, a built-in memory chip to communicate with the Optimum Charger for more work, built-in shock absorbing features to protect the battery, sixteen firm holding contact terminals for constant high power, and work in conjunction with the Optimum Charger for maximum battery life.
The new 45-minute Optimum Charger communicates with the LXT battery throughout the charge cycle using the built-in memory chip in the battery and the built-in CPU chip in the charger to recognize the history and battery condition to select the optimal charging method.  The optimal charging method uses Active 3 Controls for current control, thermal control and voltage control.  The charger also has a built-in fan to cool the battery to produce more lifetime work.
Makita has better technology with a new smart Battery Diagnostic System (sold separately) that enables users to understand the battery condition to maximize battery life.  This new system is ideal for large pro and industrial users with many batteries.  This system is able to indicate how the battery was used and can optimally refresh each cell for more lifetime work, determine the battery life expectancy based on how many times the battery has been charged or gone through a cycle and can log each battery to keep a permanent record.
Makita LXT Lithium-Ion is also backed by Makita’s new Three-Year Warranty which covers repair due to defective materials or workmanship up to three years from the purchase date.
