HSS‑E (M35 cobalt) construction: This reamer uses wear‑resistant high‑speed steel to extend tool life and maintain sharpness in demanding materials

4-flute end mills are the tool of choice for machining steel and other similarly hard metals due to having more cutting surfaces that contact the component during each revolution

The fine-pitch design is ideal for precision work in thin-wall stock or delicate materials where slot width must remain consistent from cut to cut

5xD Long Reach: Increased reach for deeper holes while preserving stability and accuracy

ISO 529 compliance ensures consistent thread form and interchangeability with standard metric threads
