2. Conical Buttons:
- Characteristics: These tungsten carbide buttons have a tapered, conical shape with a pointed or flat tip.
- メリット Offer good penetration and efficient material removal, particularly in hard rock formations.
- Ideal For: Drilling tools, rock drilling bits, and applications requiring a combination of cutting and crushing action.
3. Parabolic Buttons:
- Characteristics: These tungsten carbide buttons have a curved, parabolic shape, often with a flat or slightly indented top surface.
- メリット Provide a balance of penetration and wear resistance, making them suitable for a variety of mining applications.
- Ideal For: Drag bits, foundation drilling tools, and applications requiring a combination of cutting, scraping, and crushing action.
