Tackle the most punishing metal fabrication tasks with the DEWALT DW840 7-Inch Heavy-Duty Angle Grinder. Engineered for high-output performance, this industrial workhorse is powered by a robust 13-Amp motor that delivers a staggering 2,250 Unit Watts Out (UWO). Whether you are smoothing out heavy weld beads, grinding structural steel beams, or cutting through thick metal stock, the DW840 provides a consistent 8,000 RPM to maintain productivity in the most demanding environments. Its unique AC/DC capability allows the tool to run off generators and welders, making it an essential companion for pipeline work and remote construction sites.

Safety and efficiency are prioritized in the DW840's ergonomic design. The grinder features a keyless adjustable Type 27 guard, allowing users to quickly redirect sparks and debris away from the face and body without interrupting the workflow. Maintenance is streamlined through the integrated spindle lock button, enabling single-wrench wheel changes that get you back to work faster. Built to survive the rigors of professional use, this 7-inch grinder balances high power-to-weight ratios with a comfortable side handle, ensuring maximum control and reduced operator fatigue during long shifts of surface preparation or heavy-duty demolition.

Pro-Tip: To maximize the lifespan of your DW840, avoid applying excessive pressure during grinding. Let the weight of the tool and the speed of the motor do the work. Over-pressing can lead to premature motor wear and can glaze over your grinding wheel, reducing its cutting effectiveness. Always ensure the side handle is securely tightened to maintain full control over the torque of this 13-amp powerhouse.
