Key Performance Advantages

• Serrated Flute Design: Slotted rubber segments increase cutting aggression, promote air circulation to cool the grinding zone, and clear swarf efficiently.
• Vibration-Free Dynamic Balance: Solid metal hub ensures smooth rotation at high operational speeds, delivering crisp grind lines and chatter-free bevels.
• Long-Wearing Vulcanized Bond: Industrial vulcanized rubber compound resists heat degradation, oils, and continuous high-pressure grinding.
