High-Precision Drilling of Multiple Materials - This extremely versatile drill allows for precise drilling in hard materials like granite without slipping. This is made possible by its sharp tip and advanced geometric design. It is manufactured using a fine-tuning process from optimized carbide and is equally suitable for concrete, brick, soft ceramics, wood, and metal. Regardless of the material, it consistently delivers professional results. The hexagonal shank ensures a strong connection and maximum torque transfer in three-jaw chucks and 1/4-inch internal hex tool holders.
