The 36 V (18 V x 2) LXT? brushless 9 in power cutter kit has the power to cut through various materials with all the benefits and convenience of cordless operation. The XEC01PT1 has a maximum cutting depth of 3-1/2 in, thus can cut through standard residential concrete slab in a single pass. Besides concrete, it has the power to cut through I-beams, steel pipe (3 in), rebar (3/4 in-#6), metal stud (14 in W) and more. The benefits of a cordless power cutter over a gas power cutter include no oil/gas mixing, no emissions, no pull starts, no engine maintenance and lighter weight. This means reduced operator fatigue, instant starts, cost savings and the ability to use the power cutter indoors, in tight spaces and high elevations. An integrated water delivery system continuously feeds water for OSHA Table 1 compliance in concrete cutting applications. Water flow is controlled with an adjustment knob. The belt-drive design provides smoother operation with lower vibration. The XEC01PT1 has a purpose-built BL? brushless motor, which eliminates carbon brushes and enables the motor to run cooler and more efficiently for longer life. The brushless motor delivers 6600 rpm. Active Feedback-sensing Technology (AFT?) turns the motor off if rotation of the wheel is suddenly forced to stop. An electric brake stops the wheel in 4 seconds or less allowing for faster re-positioning. And Makita's Extreme Protection Technology (XPT?) is designed to improve a tool's operation in harsh conditions by channeling water and dust from key internal components. It's part of Makita's expanding 18 V LXT? System, the world's largest cordless tool system powered by 18 V lithium-ion slide-style batteries. Makita? 18 V LXT? lithium-ion batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger. For improved tool performance and extended battery life, Makita? created Star Protection Computer Controls?. Star Protection is communication technology that allows the Star Protection equipped tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. For increased versatility, the tool can also be powered by Makita? 18 V LXT? lithium-ion batteries with the star symbol on the battery indicating Star Protection inside. Other features of the cordless power cutter include a built-in LED light, large spindle lock button for easier wheel changes, rubberized front handle for comfort, a lock-off power switch and soft start, integrated overload indicator, LED battery charge indicator and protective battery compartment. The XEC01PT1 is a cordless solution for masons, roofers, plumbers, remodelers, construction workers, landscape and hardscape workers, metal fabricators, commercial framers, pipe fitters, vehicle mechanics, firefighters and more. The kit includes the power cutter, four 18 V LXT? 5 Ah batteries, a dual-port charger and a diamond blade and cut-off wheel.
