Makita is the innovation leader in brushless motor technology and the XT616PT Combo Kit provides BL Brushless Motor tools that deliver longer run time, increased power and speed and longer tool life. This 6-Piece Combo Kit is built for the pro-user who requires a wide range of best-in-class cordless solutions for drilling, driving, fastening, cutting, grinding and lighting. The XT616PT includes a brushless hammer driver-drill with a full 1,250 in. lbs. of Max Torque, a brushless 3-speed impact driver with 1,550 in. lbs. of Max Torque, a brushless 6-1/2 in. circular saw with a full 5,000 RPM for faster cutting, a brushless recipro saw with 2 speed settings and a 1-1/4 in. stroke length for faster cutting and a brushless 4-1/2 in./5 in. Cut-Off/Angle Grinder with 8,500 RPM and an electric brake for added productivity. The kit also includes a high-luminance single LED flashlight with 160 Lumens. It's a 1-stop solution for a wide range of applications. The kit includes two 18-Volt LXT 5.0 Ah batteries and each reach a full charge in only 45-minutes on the efficient Rapid Optimum Charger - the fastest charge-time in the category - for less downtime and increased productivity. For added convenience, the batteries feature an integrated LED battery charge level indicator. Efficient BL brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge BL brushless motor eliminates carbon brushes, enabling the BL motor to run cooler and more efficiently for longer life Electronically-controlled BL brushless motor efficiently uses energy to match torque and RPM to the changing demands of the application Variable 2-speed 1/2 in. hammer driver-drill (0 RPM - 550 RPM and 0 RPM - 2,100 RPM) with BL motor delivers 1,250 in. lbs. of max torque, weighs only 6.0 lbs. with battery for a wide range of drilling, fastening and hammer drilling applications Impact driver features 3-speed power selection switch (0 RPM - 1,100 RPM/0 RPM - 2,100 RPM/0 RPM - 3,600 RPM and 0 IPM - 1,100 IPM/0 IPM - 2,600 IPM/0 IPM - 3,800 IPM) provides 1,550 in. lbs. of max torque, weighs only 3.3 lbs. with battery Recipro saw delivers 0-2,300 (low) and 0-3,000 (high) strokes per minute and a 1-1/4 in. stroke length for faster cutting 6-1/2 in. circular saw BL motor delivers 5,000 RPM for faster cutting and ripping, cuts 2-1/4 in. at 90° and bevel capacity (0°- 50°) 4-1/2 in./5 in. cut-off/angle grinder delivers 8,500 RPM, features Automatic Speed Change technology that adjusts speed and torque during operation for optimum performance High-luminance 4 LED flashlight provides 160 Lumens, features a 12 position flashlight head Extreme Protection Technology (XPT) is engineered for improved dust and water resistance for operation in harsh conditions Equipped with star protection computer controls to protect against overloading, over-discharging and over-heating 18-Volt LXT lithium-ion 5.0 Ah battery BL1850B features an integrated LED battery charge level indicator 18-Volt LXT lithium-ion 5.0 Ah battery BL1850B reaches a full charge in 45-minutes or less 18-Volt LXT lithium-ion 5.0 Ah battery BL1850B provides up to 65% more run time per charge compared to BL1830 Dual port rapid optimum charger has a built-in fan to cool the battery for faster, more efficient charging Dual port rapid optimum charger communicates with the battery's built-in chip throughout the charging process to optimize battery life by actively controlling current, voltage and temperature 3-year limited warranty on tool, battery and charger Only use genuine Makita batteries and chargers
