Buying Guide
Backing Pad Buying Guide for Angle Grinders
Choosing the right backing pad for your angle grinder is crucial for effective and safe sanding. Heres a quick guide to help you select the best one.
Size and Compatibility
Ensure the backing pads diameter matches your angle grinders specifications. Common sizes are 4.5 inches, 5 inches, and 7 inches. Verify the thread size; the most common is 5/8-11 thread.
Material
Consider the pads material. Durable urethane pads offer good flexibility and control, while firmer rubber pads are suitable for aggressive sanding. Choose a pad material that complements your sanding disc material and the surface you are working on.
Hardness/Density
The pads hardness impacts sanding performance. Softer pads conform to curves and contours, ideal for detailed work. Firmer pads provide a flatter surface, which is best for flat surfaces and achieving aggressive stock removal. Consider the project you are undertaking.
Attachment Type
Backing pads typically use hook-and-loop (Velcro) or pressure-sensitive adhesive (PSA) systems for attaching sanding discs. Hook-and-loop offers ease of changing discs. PSA pads provide a strong bond, but are typically single use.
Frequently Asked Questions
What size backing pad do I need for my angle grinder?
The backing pad size needs to match your angle grinders disc capacity. Common sizes include 4.5-inch, 5-inch, and 7-inch. Check your grinders specifications or the existing disc size to ensure compatibility before purchasing.
What types of sanding discs are compatible with backing pads?
Most backing pads are designed to work with hook-and-loop (velcro) sanding discs. These discs are easy to attach and remove. Some backing pads may also work with PSA (pressure-sensitive adhesive) discs, but confirm compatibility before use.
How do I attach a backing pad to my angle grinder?
Backing pads typically thread onto the angle grinders spindle. Remove the existing grinding disc and any retaining nuts. Then, screw the backing pad firmly onto the spindle. Always ensure the pad is securely attached before sanding.
What material should I choose for my backing pad?
Consider the material of the backing pad based on your project. Urethane backing pads are popular for their flexibility and durability, suitable for various applications. For more aggressive sanding, a stiffer backing pad may provide better results.
How do I maintain my backing pad?
Regularly inspect the backing pad for wear and tear. Clean the pads surface to remove dust and debris after each use, which can extend its lifespan. Replace the pad if it becomes damaged or worn, as this can affect sanding performance.
