Dewalt DW801 4" 220V Angle Grinder

Key specs include a 4-inch grinding wheel, 220V motor, spindle lock for easy wheel changes, a safety switch, a two-position side handle for better control, and a dust-sealed switch to protect the motor from dust and debris.

First unplug the grinder. Press and hold the spindle lock, then rotate the wheel to align the locking tab. Use the hex wrench to loosen the nut, remove the wheel, install the new wheel, tighten the nut, release the spindle lock, and recheck that the wheel is securely mounted.

It has a safety switch to prevent accidental start-up, a spindle lock for quick wheel changes, and a dust-sealed switch to protect the internal components from dust and debris. The 4" wheel also helps keep guards and control favorable for safe operation.

The DW801 offers a two-position side handle. Attach it on the left or right side depending on your dominant hand and task. Positioning the handle opposite the wheel direction gives you better control and reduces kickback during grinding or cutting.

It’s ideal for metal cutting and grinding tasks, such as deburring, stock removal, edge grinding, and preparing metal surfaces for welding or finishing.

Choose a compatible 4" wheel rated for the grinder’s RPM, secure the wheel with the spindle nut using the spindle lock, attach the wheel guard, connect to a suitable 220V power source, andwear appropriate PPE (gloves, eye protection, and a face shield). Start with light passes and maintain a firm grip with the side handle engaged.

This grinder accepts standard 4" grinding wheels and cutoff wheels designed for 4" diameters. Always verify the wheel’s RPM rating matches or exceeds the grinder’s no-load speed and follow wheel manufacturer guidelines.

If your workshop is wired for 220V and you’re performing heavy-duty metal grinding, the 220V DW801 is well-suited for sustained performance. If your setup is limited to 110V or you’re doing lighter tasks, a 110V grinder with appropriate power ratings might be more convenient. Always match the tool to your power supply and task load.

Keep vents clear of dust, regularly inspect and replace worn wheels, guard, and brushes if applicable, and store the grinder in a dry place. Periodic cleaning and using a dust extraction attachment when grinding can extend life and performance.

Consider the DW801’s build quality, 4" wheel versatility, and 220V suitability as part of its value. If it doesn’t meet your needs, you can evaluate the return terms on Fepy.com for a hassle-free options-based return process.
