- Engraving: Select an appropriate engraving bit for your material (e.g., wood, glass, metal, crystal). Start with a lower speed and apply light, consistent pressure. Practice on scrap material first.
- Polishing: Use the designated polishing bits. Apply polishing compound if necessary for optimal results. Move the pen smoothly over the surface.
- Sanding/Grinding: Choose suitable grinding bits. Maintain a steady hand and avoid excessive pressure to prevent damage to the material or the bit.
