The Dormer Pramet C505 5.0mm HSS-E ball-nose end mill is a compact, high-precision cutter designed for profiling and contouring in metalwork. It’s ideal for copy milling in free-machining steel and copper alloys, delivering smooth, accurate finishes on complex 3D features.

• Diameter: 5.0 mm
• Flutes: 2-flute ball-nose end mill for smooth axial and radial engagement
• Radius: 2.5 mm full-profile radius for gentle, accurate fillets
• Length of Cut: 13 mm (DOC) suitable for shallow pockets and contours
• Overall Length: 57 mm, providing adequate reach for general-purpose milling
• Shank: 6 mm Weldon shank with a flat for secure clamping
• Material & Finish: HSS-E (cobalt-based) with bright finish for improved wear resistance
• Helix Angle: 30° for efficient chip evacuation and smooth cutting in soft to medium-hard materials
• Rake Angle: 12° to enhance cutting action and reduce built-up edge
• Standard: DIN 844 K compatible for consistent interchangeability
• Applications: Copy milling and contouring in free-machining steel and copper/copper alloys

Designed for reliability in precision metalworking, this tool pairs a robust cobalt-based HSS-E composition with a flatted shank that stays securely clamped, even in demanding operations. The 2-flute geometry provides a balance between rigidity and efficient chip clearance, while the ball-nose profile enables accurate filleting and smooth transitions along complex surfaces. Its DIN 844 K specification ensures compatibility across compatible milling setups, making it a dependable choice for engineers and machinists targeting consistent, repeatable results in steel and copper alloys.
