Choosing The Right Sanding Disc
Replacing sanding discs is simple when you know how to pick the right one. The correct disc helps you get smooth surfaces fast.
This guide covers types of sanding discs, grit choices, and which materials work best together.
Types Of Sanding Discs
Sanding discs come in many styles. Each type fits different tasks and tools.
- Aluminum oxide discs are good for wood and metal.
- Silicon carbide discs work well on plastic and paint.
- Ceramic discs last longer and cut fast on hard metals.
- Garnet discs are gentle, ideal for fine wood sanding.
Grit Selection Tips
Choosing the right grit number is key for good results. Low grit means coarse and high grit means fine.
| Grit Number | Use |
| 40-60 | Remove paint or rough shaping |
| 80-120 | Smooth wood or metal surfaces |
| 150-220 | Finish sanding before painting |
| 320+ | Polish and fine finishing |
Material Compatibility
Match your sanding disc to the material you work on. Wrong discs wear out fast or damage surfaces.
