Frequently Asked Questions

AI
While often used interchangeably, I/O blocks typically refer to industrial-grade blocks designed for specific input/output tasks in manufacturing or heavy-duty sanding, whereas standard blocks are for general DIY. However, many high-end sanding blocks serve both purposes with superior grip and flatness.
Rubber and foam provide excellent shock absorption and conform to curved surfaces, making them ideal for wood and paint. Hard plastic or metal blocks are better for flat, rigid surfaces where maintaining a perfectly flat plane is crucial for filler or metalwork.
Match the block size to your sandpaper discs. Common sizes include 125mm and 150mm. Larger blocks cover more area faster but are harder to control on edges. Smaller blocks offer better precision for detailed work and tight corners.
