Achieving "breakage resistance and long life" and "stable processing with minimal variation" required for small-diameter drills. A newly developed carbide material that balances hardness and toughness through original component design specifically for micro drills. The groove shape emphasizes drill rigidity and chip evacuation, resulting in a drill that is less prone to breakage. In small-diameter hole drilling, there are many issues such as "[prone to sudden breakage and short tool life]" and "[unstable processing due to variations in hole position accuracy]." To address these problems, the Aqua REVO Drill Micro has been developed. By adopting original component design and ultra-fine particle carbide, a new carbide substrate specifically for micro drills has been developed. Compared to the conventional Aqua REVO Drill, toughness and hardness have been further enhanced. Additionally, to suppress sudden breakage caused by chip clogging, a groove shape with increased core thickness has been adopted, enhancing chip evacuation and tool rigidity. For the coating, the REVO-D coat optimized for micro drills has been adopted. The ultra-smooth treatment reduces resistance during cutting and improves chip evacuation. Achieving "breakage resistance and long life" and "stable processing with minimal variation" required for small-diameter drills.

■ A thinning shape that reduces drill runout and a corner shape that cuts off burrs without leaving any at the exit. ■ Outstanding burr-free performance even in the processing of cross holes, where deburring is difficult, enabling a reduction in deburring work hours. ■ Burr-Free Series Reduces burrs at the exit of through holes to zero. Challenging the conventional wisdom that "burrs are inevitable in cutting processes" and "deburring after processing is a given," the "Burr-Free Series" has finally been born. It is now possible to eliminate the essential secondary processing of deburring, achieving a reduction in processing time and significant cost savings.
