Designed for precision in small features, the C123 slot drill delivers clean slotting with strong edge retention and predictable performance. The powder-metallurgical HSS-E core enhances hardness and wear resistance, helping the tool maintain sharpness through repetitive cuts. The 30° helix reduces cutting forces and helps minimize burrs, while the 12° rake angle supports efficient chip formation in a variety of metals. The flatted 6 mm shank ensures stable alignment in standard tool holders, enabling repeatable results in tight slots and delicate shoulders. This combination makes it an excellent choice for electronics enclosures, intricate fixtures, and precision-machining tasks where consistent, high-quality slots matter.
