This Dewalt impact wrench will deliver up to 447nm of fastening torque with no need to worry about over-tightening The Dewalt DCF894N is a Mid-Range Cordless Impact Wrench with Detent Pin Anvil delivering up to 447nm max of fastening torque. This tool also features Precision Wrench Control, which helps to prevent overtightening in forward and fastener run-off in reverse. The fully brushless motor delivers exceptional power for the most demanding tasks, in a compact form. This model is ideal for grooved couplings, pipe flanges, wheel lugs, concrete anchor setting, and many other applications where a lot of torque is needed in a compact space.  Features: Brushless motor provides exceptional power and runtime for the most demanding tasks Powerful fan cooled motor delivers up to 447Nm of torque and 3100 impacts per minute for heavy-duty fastening applications At just 178mm long and weighing only 1.5kg, the tool retains power whilst being compact enough to get into tight spaces 3 mode settings (Low, Precision Wrench, High) for optimal control over fastening applications, reducing the risk of damage to material, accessories and components \"Low mode\" runs at a slower speed in forwards for more delicate fastening applications, but runs at full speed in reverse where high torque is less of a problem Precision Wrench in forward runs the fastener is run up at full speed until the tool starts to impact. As soon as this happens the tool pauses to allow the user to stop, then impacts at 3100ipm if more torque is required Precision Wrench in reverse impacts at high speed to loosen the fastener. Once the tool senses that the fastener is loose, it slows down to prevent running the fastener off High speed offers full speed in forward and reverse 1/2\" (13 mm) square drive with detent pin allows for more efficient torque delivery and excellent socket retention Bright white LED located on foot of tool with delay feature for improved visibility and flashlight functionality Comfortable rubber XR grip and switch for greater application comfort and maximum control Up to 813Nm of \"breakaway\" torque for stubborn bolts Comes With: Belt clip Specification: Max Torque: 447 Nm Impacts per Minute: 3100 ipm Weight: 1.5 kg Length: 178 mm Sound Pressure: 94 dB(A) Sound Pressure Uncertainty: 3 dB(A) Sound Power: 105 dB(A) Sound Power Uncertainty: 3 dB(A) Battery Chemistry: Li-Ion
