Dewalt DCF891N-XJ XR Brushless 1/2 Compact High Torque Wrench give you Up to 1152 breakaway torque (813 Nm of fastening torque) ensures removal of the tightest bolts. Ultra compact, light weight design allows for use in confined areas using its Square drive with hog ring allows quick socket changes. Variable trigger allows complete control over all applications Efficient brushless motor delivers high performance, extends tool life and allows for much shorter design Bright white LED with delay feature for improved visibility and functionality. Now with brightness control so you can dim or turn off the light to suit the environment. Comfortable rubber XR grip and switch for greater application comfort and maximum control. Mode 1 � Low Speed Tool operates at a reduced speed (approx. 1/3) in forward to help prevent overtightening of small fasteners. Forward : Tool operates at a reduced speed and outputs approximately 160Nm Reverse : Tool operates at normal speed Mode 2 - Mid Speed Tool operates at a reduced speed (approx. half) in forward to help prevent overtightening of small fasteners. Forward : Tool operates at a reduced speed and outputs approximately 400Nm Reverse : Tool operates at normal speed Mode 3 � High Speed Tool operates at a normal speed in forward and reverse. Forward :Tool operates at normal speed. Reverse :Tool operates at normal speed. Precision wrench Helps to prevent overtightening in forward and fastener run-off in reverse. Forward :Tool pauses before impacting to help prevent over tightening. Reverse : Tool lowers speed when fastener is loose to help prevent run-off Dewalt DCBP518 Powerstack Features Higher max watts out, so there's a greater range of applications Faster speed of application, giving you increased output and more jobs done Improved thermal performance. Pouch cells run cooler in application and dissipate heat better than cylindrical cells Create less heat resistance which means fewer
