Dormer Pramet C247 22.0mm HSS-E-Powder Metal Flatted Shank Multi-Flute Standard Length End Mill DIN 844 K

Engineered for reliable precision milling in free‑machining steels and copper alloys, the Dormer Pramet C247 22.0 mm HSS‑E powder metallurgical end mill is a robust standard‑length tool designed for shoulder milling, slot milling, and ramping. Its 5‑flute geometry and advanced HSS‑E core deliver consistent performance across demanding milling tasks.

• Diameter: 22.0 mm with a 38 mm length of cut for deep slots and pockets
• Overall length & reach: 104 mm total length with 53.5 mm reach and neck relief for access to tight spaces
• Material: HSS‑E powder metallurgy with a bright finish, offering higher hardness and wear resistance
• Shank: 20 mm Weldon shank with a flat for a secure, positive drive
• Flutes: 5‑flute geometry providing rigidity and efficient chip evacuation
• Helix angle: 30° for smooth cutting action and stable performance
• Rake angle: 12° to enhance cutting edge performance during shoulder milling
• DIN standard: DIN 844 K compatibility ensures interchangeability with standard holders and equipment
• Applications: Shoulder milling, slot milling, and ramping in free machining and plain carbon steel, copper, and copper alloys

The combination of a 22 mm diameter and five flutes enables efficient material removal at steady feeds while maintaining a stable cut. The powder‑metallurgy HSS‑E core delivers enhanced wear resistance and toughness for longer tool life in tough milling conditions. The 30° helix and 12° rake angle optimize cutting forces, reduce chip clogging, and yield clean shoulders and slots. The extended reach with neck relief allows deeper pockets and precise ramping without sacrificing rigidity, while the Weldon shank provides a secure, repeatable grip in collets or chucks. This end mill is well suited for production environments that require accuracy, reliability, and versatility in free machining steels and copper alloys.
