For a belt sander, the choice of sandpaper grit depends on the task and the material you're working with: 1. **Coarse Grit (40-60):** Use this for heavy material removal, such as stripping paint or smoothing out rough surfaces. It's ideal for initial sanding on rough wood or removing old finishes. 2. **Medium Grit (80-120):** This is suitable for general-purpose sanding. It can be used for smoothing surfaces after using coarse grit or for preparing wood for finishing. It's also effective for removing minor imperfections. 3. **Fine Grit (150-180):** Use fine grit for the final sanding before applying finishes. It helps in achieving a smooth surface and is suitable for light sanding between coats of paint or finish. 4. **Very Fine Grit (220-400):** This is used for ultra-smooth finishes and for sanding between coats of finish. It's not typically used with a belt sander, as it's more suited for hand sanding or orbital sanders. 5. **Extra Fine Grit (600 and above):** Rarely used with belt sanders, this grit is for polishing and achieving a high-gloss finish on surfaces like metal or plastic. Choose the grit based on the stage of your project and the desired finish. Start with a coarser grit for initial sanding and progress to finer grits for finishing. Always ensure the sandpaper is compatible with your belt sander's specifications.

Yes, a belt sander can be used on metal, but there are important considerations to ensure safety and effectiveness. Belt sanders are typically designed for wood, but with the right abrasive belt, they can be adapted for metalworking tasks such as deburring, finishing, or shaping metal surfaces. 1. **Abrasive Belts**: Use belts specifically designed for metal. These belts are usually made from materials like aluminum oxide, zirconia, or ceramic, which are capable of grinding metal effectively. 2. **Speed and Power**: Metal requires more power and slower speeds compared to wood. Ensure your belt sander has adjustable speed settings to prevent overheating and damaging the metal or the tool. 3. **Cooling**: Metal sanding generates significant heat. Use cooling methods such as water or air to prevent overheating, which can damage both the metal and the abrasive belt. 4. **Safety Precautions**: Wear appropriate personal protective equipment (PPE) such as safety goggles, gloves, and a dust mask. Metal sanding produces sparks and fine metal dust, which can be hazardous. 5. **Tool Maintenance**: Regularly check and maintain your belt sander. Metal dust can accumulate and cause wear or damage to the tool.
