◎ The suitability and use cases comparison evaluates which grit and size combination fits your specific project requirements.
| Use Case | Recommended Product | Why |
|---|
| Final surface smoothing and finishing | GRAPHITE 55H778 K120 | The fine K120 grit delivers a smooth surface finish ready for painting or varnishing without deep scratch marks. |
| Intermediate surface leveling | GRAPHITE 55H776 K80 | Medium grit efficiently removes previous sanding marks and prepares the material for finishing. |
| Coarse material removal and stripping | GRAPHITE 55H774 K40 | Coarse K40 grit is ideal for rapidly removing heavy layers of material from rough workpieces. |
| General-purpose medium sanding | GRAPHITE 55H775 K60 | K60 grit balances efficient material removal speed with an acceptable surface smoothness. |
| Stationary sanding with Scheppach BTS800 | Scheppach BTS800 K120 | The larger belt dimensions are specifically engineered to fit this exact stationary machine model. |
The choice between these options depends heavily on the project stage and your sanding equipment. The GRAPHITE 55H778 is best suited for fine finishing and smoothing tasks using standard portable belt sanders. If your project requires aggressive material removal, select lower grit options from the same brand, and ensure you use dedicated sizes if operating stationary workshop machinery.
