A Double Ended Holder has ER collet openings on both ends, allowing two cutting tools to be mounted in one holder. This setup improves efficiency by reducing tool change time and increasing machining flexibility.
2. Why choose Double Ended Holders? ▼
They help increase productivity by enabling fast switching between two tools without changing the holder. This is especially useful in repetitive operations or when multiple tools are used in sequence.
