The DWE4519 is a corded 9-in. large angle grinder with a 4 HP motor delivering 6,500 RPM for maximum surface coverage on metal, concrete, and masonry. The slide switch with lock-on supports extended operation on large-area tasks. A 2-position side handle provides grip flexibility. The 9-in. disc diameter is the largest wheel format in DEWALT's corded lineup, making the DWE4519 suited for high-volume material removal. Compatible with standard 9-in. wheels. Carries DEWALT's 3-year limited tool warranty.
What is the DWE4519 best suited for?
The DWE4519 is suited for large-scale material removal: wide concrete surface preparation, stripping large weld seams on structural steel, cutting through thick masonry, and any task where the largest possible wheel diameter reduces total work time.
Why is the DWE4519's RPM lower than smaller grinders?
The 6,500 RPM no-load speed is lower than smaller grinders because the 9-in. wheel has a larger circumference. The peripheral speed of the wheel edge — what actually does the grinding — is comparable to smaller wheels at higher RPM. Lower RPM is also safer for large-diameter discs.
Does the DWE4519 have a lock-on switch?
Yes. The DWE4519 uses a slide switch with lock-on, allowing extended operation without continuous trigger pressure. This is practical for large-format grinding tasks that may last several minutes per pass.
How heavy is the DWE4519?
The DWE4519 weighs 13.85 lbs. This makes it the heaviest grinder in DEWALT's corded lineup and reflects the larger body and motor needed to drive a 9-in. wheel. Two-handed operation is expected.
What disc size does the DWE4519 use?
The DWE4519 uses 9-in. (230mm) grinding and cutting wheels. One 9-in. guard is included. 9-in. wheels are available in grinding, flap, and cutting configurations.
How does the DWE4519 compare to the DCG460X2 cordless 9-in. grinder?
The DWE4519 provides unlimited corded runtime and costs significantly less. The DCG460X2 is cordless for mobile use without an extension cord and adds Kickback Brake, E-Clutch, and a No-Volt switch. Choose the DWE4519 for stationary or plugged-in heavy grinding; choose the DCG460X2 for job sites without accessible power.
