CAT40 45-degree Drawbolt Retention Knobs - Improved connection: designed for a 45-degree orientation to provide a secure and reliable connection between the tool holder and the milling machine. - Strength and flexibility: made from 40Cr material with a hardened housing for increased strength; resists tearing or breaking under heavy milling. - Compatibility: compatible with mills such as VF, Mini Mill, ES, and more. Suitable for machines with spindle coolant and for machines without through-spindle coolant. - Durability: hardness and crack-resistance tested; black oxide finish improves heat resistance and reduces distortion, extending life. - Practical packaging: pack of 10 CAT40 drawbolts for easy replacement; install in the tool holder for a secure connection. Use cases: - Heavy milling of pockets or slots on VF-series or ES-series machines with end mills. - Quick changeovers and spare parts during long production runs. - Setups using spindle coolant or non-through coolant configurations.
