Porter Cable Grinder Review
Choosing the Right Porter-Cable Angle Grinder
Motor Power & Application
The motor’s amperage is a primary factor. A 7.5-amp motor (like in the PORTER-CABLE 7.5-Amp Angle Grinder) provides more power for demanding tasks like cutting thicker metal or aggressive grinding. A 6.0-amp motor (PORTER-CABLE 6.0-Amp 4-1/2-Inch Grinder) is sufficient for lighter work and offers a good balance of power and affordability. Cordless models, utilizing a 20V battery (PORTER-CABLE 20V Cordless 4.5 in Grinder), trade some raw power for portability; their 8,500 RPM is great for many tasks, but may struggle with very heavy-duty cutting. Consider the materials you’ll be working with most frequently – heavier materials demand higher amperage or a robust battery system.
Durability & Build Quality
Porter-Cable angle grinders consistently feature cast metal gear housings. This is crucial for longevity, especially on a jobsite. A cast metal housing significantly improves durability compared to plastic alternatives, resisting damage from drops and impacts. Look for grinders with this feature to ensure they withstand regular use. A durable grinder saves you money in the long run by reducing the need for replacements.
Control & Comfort Features
User comfort and control impact accuracy and reduce fatigue. A 3-position adjustable side handle is a standout feature, allowing you to customize the grinder’s balance and grip for different applications. A soft grip handle further enhances comfort during extended use. These seemingly small details make a big difference when you’re working on a project for hours.
Additional Features to Consider
- Spindle Lock: Allows for quick and easy wheel changes with a single wrench. This is a standard feature on most Porter-Cable models and saves significant time.
- Tool-Free Guard Adjustment: Some models offer tool-free guard removal (like the 6.0-Amp model), making adjustments faster and more convenient.
- Switch Type: A slide switch with a lock-on feature (found on the 6.0-Amp model) can be useful for continuous grinding tasks, reducing hand fatigue.
- Corded vs. Cordless: Corded grinders offer consistent power, while cordless grinders provide portability. Consider your workspace and project requirements.
- RPM (Revolutions Per Minute): Higher RPM typically means faster material removal, but may also require more control.
