Designed with a 2‑flute configuration, this slot drill excels at evacuating chips in slots while preserving rigidity for accurate cutting. The cobalt‑based HSS‑E alloy enhances wear resistance and heat tolerance, enabling steady performance under demanding milling conditions. The flatted Weldon shank provides secure gripping and minimizes runout in collets, contributing to precise slot dimensions. With a generous reach and neck relief, you can reach deeper slots without sacrificing stability, making it a practical choice for repetitive slotting tasks and precision fabrication.
