- Material: HSS‑E (high‑speed steel with cobalt) for enhanced hardness and wear resistance during demanding cuts
- Coating: Steam Oxide coating to reduce friction, improve wear resistance, and aid chip control
- Flute design: Spiral flute geometry engineered for efficient chip evacuation in blind holes, helping prevent clogging and heat buildup
- Application: Ideal for threading in blind-hole situations across steel, cast iron, and alloy metals
