The Zola diamond conical drill bit is a professional tool designed for precise drilling, correction, and controlled enlargement of holes in hard and very hard materials. Made from manganese steel and equipped with vacuum-bonded diamonds, this drill offers fast cutting, high stability, and clean edges, even in demanding applications. It is a versatile solution for installation, assembly, and finishing, suitable for both professional use and advanced DIY projects.
Main Advantages- Multiple applications in one tool – Enables initial drilling, precise correction, milling, and hole enlargement without changing accessories, saving time and increasing work efficiency.
- Diamonds vacuum-bonded across the entire surface of the conical section – Uniform diamond layer ensures steady cutting, increased speed, and reduced wear, without causing breakages or cracks in the material.
- Wide diameter range 2–35 mm – One cone covers many installation and assembly applications, from fine adjustments to controlled enlargements.
- M14 Compatibility – M14 shank for direct use with angle grinders, no additional adapters required.
- Operation in wet or dry conditions – Can be used dry for quick interventions or wet for efficient cooling and extended lifespan.
- Durability and stability – Manganese steel body provides stiffness and control, reducing vibrations and improving accuracy.
