1. Durable and LonglastingThe precision drill holder undergoes carburizing and quenching processes, enhancing its hardness, antifatigue, and wear resistance. This ensures longlasting durability and reliability with every drill. 2. Precision and PerformanceThrough a onetime forming process, the tool holder maintains rotational accuracy, enabling precise and accurate drilling. This precision enhances overall performance, resulting in efficient and effective drilling. 3. Smooth and PreciseThe drill holder is finely polished inside and out, delivering a smooth and precise tool. This fine polishing enhances machining effects, allowing for cleaner and more accurate drilling results. 4. Stable and ReliableWith design and manufacturing, the drill holder provides stable and reliable performance. This stability not only improves machining efficiency but also ensures consistent and dependable drilling results.
