Dormer Pramet C247 6.5mm HSS-E-Powder Metal Flatted Shank Multi-Flute Standard Length End Mill DIN 844 K

The Dormer Pramet C247 6.5 mm HSS-E powder-metallurgical end mill is a compact, four-flute cutting tool designed for shoulder milling, slot milling, and ramping in free‑machining steels and copper alloys. Built to DIN 844 K standards with a 10 mm Weldon shank, it delivers reliable performance in common milling setups.

• Diameter: 6.5 mm end mill for precise, tight‑radius milling in pockets and shoulders
• Flutes: 4‑flute geometry to balance material removal, finish, and feed‑rate capability
• Length specs: 16 mm length of cut (LOC) with a 66 mm overall length (OAL) for reach into mid‑depth features
• Shank: Weldon shank 10 mm, providing rigid clamping and compatibility with standard holders
• Material: Powder-metallurgical HSS‑E with bright finish for improved edge retention and wear resistance
• Geometry: 30° helix and 12° rake angle optimized for shoulder and slot milling, plus smooth ramping
• Standard: DIN 844 K compliance ensures compatibility with common machines and tooling systems
• Applications: Ideal for free‑machining and plain carbon steel as well as copper and copper alloys

This end mill combines robust edge retention with efficient chip evacuation, enabling stable, consistent cuts even in challenging materials. The powder‑metallurgical HSS‑E core supports higher performance than standard HSS, while the bright finish reduces friction and helps maintain a clean tool surface. The 10 mm Weldon shank provides a secure grip in tool holders, minimizing runout during high‑speed milling. With its compact 6.5 mm diameter and practical 16 mm LOC, it’s well suited for precision pocketing, shallow shoulder features, and finishing passes in everyday machining tasks.
