  • 【35mm Extended Diamond Surface – Faster, Cleaner Grinding & Drilling】 Features an ultra-wide 35mm diamond-coated grinding surface—over 3× wider than typical 8–10mm bits—for faster material removal and smoother drilling. The high-hardness diamond resists wear and deformation, ensuring cleaner holes and longer tool life
