| Plastic, Composites | Aluminum Oxide (AO) or Silicon Carbide (SiC) – sharp, low heat | 4½", 5", 7" | 60–80 / 100–180 | Edge shaping, flash removal, light surface prep | Use light pressure to avoid melting plastic |
| Soft Metals (Aluminum, Brass) | Silicon Carbide (SiC) or Zirconia Alumina (ZA) for aggressive work | 4½", 5", 7" | 36–80 / 100–150 | Deburring, paint/oxidation removal, light shaping | SiC for smooth finishes; ZA for heavier stock removal |
| General Metals (Mild Steel, Iron) | Zirconia Alumina (ZA) – self-sharpening, durable | 4½", 5", 7", 9" | 24–50 / 60–120 | Weld removal, beveling, aggressive grinding | Apply steady pressure to activate self-sharpening action |
| Hard Metals (Stainless Steel, Titanium) | Ceramic – long-lasting, cool cutting | 4½", 5", 7", 9" | 24–50 / 60–120 | Heavy grinding, prolonged use, heat-sensitive materials | Empire Upgrade: Our ceramic discs last 50–200% longer and resist loading |
