Designed for precision shoulder milling and slot milling in free‑machining steels and copper alloys, the Dormer Pramet C273 8.0 mm HSS‑E powder metallurgical end mill delivers reliable performance with long reach and consistent results.

• Diameter: 8.0 mm
• Flutes: 4-flute geometry for efficient chip evacuation and stable cutting
• Length of cut: 38 mm
• Overall length: 88 mm
• Shank: 10 mm Weldon shank with a flat for secure seating and reduced runout
• Material / finish: Powder metallurgical HSS‑E with a bright finish for enhanced hardness and wear resistance
• Helix angle: 30° for smooth cutting action and good surface finish
• Rake angle: 12° to improve cutting efficiency and reduce built-up edge on copper alloys
• Standard: DIN 844 L compliance, ensuring consistent size and compatibility
• Applications: Shoulder milling and slot milling in free machining steel, plain carbon steel, and copper or copper alloys

The combination of a long 38 mm cut length and an 88 mm overall length provides notable reach for deep pockets and extended milling operations without frequent tool changes. The 4‑flute design accelerates material removal while maintaining stability, and the 30° helix paired with a 12° rake angle helps achieve clean edges and reliable chip control across challenging alloys. Built on a robust HSS‑E powder metallurgical foundation, this end mill is engineered for durability in everyday machining tasks while delivering dependable, repeatable results.
