The specific runtime will vary depending on the battery's amp-hour (Ah) rating and the intensity of the task. Higher Ah batteries will provide longer runtimes, allowing you to work uninterrupted for extended periods.

- Disc Size: As the name suggests, this grinder uses 4-1/2 inch diameter discs. This size is a sweet spot for versatility, offering a good balance between cutting depth and maneuverability. It's large enough to handle substantial tasks yet compact enough for detailed work.
- Spindle Lock: A spindle lock is a must-have feature for any grinder, and this Porter-Cable model includes one. The spindle lock allows you to quickly and easily change the grinding or cutting disc. By locking the spindle, you can securely loosen and tighten the retaining nut, making disc changes a breeze. This saves time and frustration, especially when you need to switch between different tasks frequently.
- Adjustable Guard: Safety is paramount when working with power tools, and the adjustable guard is a key safety feature. It protects you from sparks and debris generated during grinding and cutting. The guard can be easily adjusted to different positions, providing optimal protection for various applications and working angles. Always make sure the guard is properly positioned before starting any grinding or cutting task.
- 3-Position Side Handle: Ergonomics play a significant role in tool usability, and the 3-position side handle enhances comfort and control. You can attach the handle on either the left or right side of the grinder, or at the top, depending on the task and your preference.

How to Use the Porter-Cable 4-1/2 in. Diameter 20V Max Angle Grinder Tool Safely
Safety should always be your top priority when using power tools. Angle grinders can be dangerous if not used properly, so let's go over some essential safety tips:
Wear Safety Gear
Always wear appropriate safety gear, including safety glasses, gloves, and a dust mask or respirator. Safety glasses protect your eyes from flying debris, gloves protect your hands from cuts and abrasions, and a dust mask or respirator prevents you from inhaling harmful particles. It might seem like overkill, but it’s better to be safe than sorry.
Use the Correct Disc
Make sure you're using the correct disc for the task at hand. There are different discs for grinding, cutting, polishing, and sanding, each designed for specific materials and applications. Using the wrong disc can be dangerous and can damage the tool or workpiece. Always check the disc's specifications and intended use before attaching it to the grinder.
Inspect the Disc
Before each use, inspect the disc for any signs of damage, such as cracks or chips. A damaged disc can shatter during use, posing a serious safety hazard. If you find any damage, discard the disc and use a new one. It's a small price to pay for peace of mind.
Secure the Workpiece
Always secure the workpiece firmly before grinding or cutting. Use clamps or a vise to hold the material in place, preventing it from moving during operation. A stable workpiece is essential for accurate and safe grinding and cutting.
Use the Guard
Never remove the guard from the grinder. The guard protects you from sparks and debris, and it also helps prevent accidental contact with the spinning disc. Make sure the guard is properly adjusted to provide maximum protection.
Maintain a Firm Grip
Hold the grinder with a firm grip, using both hands. The side handle provides additional control and stability. Avoid using the grinder one-handed, as this can lead to loss of control and potential injury. A secure grip is crucial for accurate and safe operation.
Work in a Well-Ventilated Area
If you're grinding or cutting materials that produce dust or fumes, work in a well-ventilated area. This helps prevent the buildup of harmful particles in the air. If necessary, use a dust mask or respirator to protect your lungs.
Avoid Overheating
Don't push the grinder too hard, as this can cause it to overheat. Let the tool do the work, and avoid applying excessive pressure. Overheating can damage the motor and reduce the tool's lifespan. Take breaks as needed to allow the grinder to cool down.
Maintenance Tips for Your Porter-Cable Angle Grinder
To keep your Porter-Cable 4-1/2 in. Diameter 20V Max Angle Grinder Tool in top condition, regular maintenance is essential. Here are some tips to help you keep your grinder running smoothly:

Check and Replace Discs
Regularly inspect the grinding and cutting discs for wear and damage. Replace worn or damaged discs promptly to ensure optimal performance and safety. Using worn discs can reduce cutting efficiency and increase the risk of breakage.
Lubricate Moving Parts
Periodically lubricate the moving parts of the grinder, such as the spindle and gears. Use a high-quality lubricant to reduce friction and wear. Proper lubrication extends the life of the tool and ensures smooth operation.
Inspect the Power Cord and Battery
For cordless models, check the battery and charger for any signs of damage. Replace the battery if it no longer holds a charge or if it shows signs of deterioration. For corded models, inspect the power cord for frays or cuts and replace it if necessary.
