Industrial Grinding Dominance: High-Output 4.7 HP 7-Inch Angle Grinder with Dust Ejection and Advanced Vibration Control

The DEWALT DWE4557 7-Inch Angle Grinder is a professional-grade powerhouse engineered for the most demanding material removal applications. Driven by a massive 4.7 HP motor delivering up to 8,500 RPM, this tool provides the highest power-to-weight ratio in its class. Whether you are grinding down heavy welds, cutting structural steel, or performing intense surface preparation, the DWE4557 maintains higher operating speeds under load to ensure maximum productivity. The specialized low-profile gearcase allows you to access tight corners and restricted spaces without sacrificing the industrial torque required for the job.

Built for long-term durability on the toughest jobsites, this grinder features DEWALT’s innovative Dust Ejection System™, which clears damaging debris from the air intake to prevent motor abrasion and extend brush life. To ensure operator comfort during extended use, the tool is equipped with an Anti-Vibe trigger handle and a 3-position side handle, significantly reducing vibration fatigue. With a heavy-duty "S" style cord designed to withstand shop abuse and automatic turn-off brushes that protect the motor from damage, the DWE4557 is the definitive choice for mechanical contractors, ironworkers, and concrete professionals.

Specifications

Pro-Tip: To extend the life of your motor and gearset, let the 8,500 RPM speed do the work rather than leaning into the tool. Forcing a 7-inch grinder can lead to glazing the wheel and excessive heat buildup; a light, steady touch allows the 4.7 HP motor to clear material efficiently while keeping the workpiece cool.
