Meet the Dormer Pramet C247 28.0 mm HSS-E end mill — a six-flute, short-series tool designed for shoulder milling, slot milling, and ramping in free‑machining and plain carbon steels as well as copper alloys. Built to DIN 844 K standards, it combines a robust Weldon shank with powder-metallurgical HSS‑E and a bright finish for reliable, precise cutting performance.

• Diameter: 28.0 mm
• Flute count: 6-flute geometry for efficient material removal
• Length of cut: 45 mm
• Overall length: 121 mm
• Reach with neck relief: 64.5 mm
• Shank type: Weldon, 25 mm
• Material and finish: Powder‑metallurgical HSS‑E with bright finish
• Helix and rake: 30° helix, 12° rake for shoulder and slot milling
• Standard: DIN 844 K
• Applications: Shoulder milling, slot milling, ramping
• Material compatibility: Free‑machining and plain carbon steel, copper and copper alloys

This end mill is engineered to deliver solid rigidity and consistent chip formation across medium-depth cuts. The 30° helix supports smooth cutting action and good surface finish, while the 12° rake enhances cutting efficiency in softer metals and helps prevent built‑up edge. With a 25 mm Weldon shank, it clamps securely in common tool holders, enabling repeatable accuracy on CNC and manual machines. The powder-metallurgical HSS‑E substrate provides enhanced hardness and wear resistance, extending tool life in demanding machining cycles. Whether you’re removing material from free‑machining steel or shaping copper alloys, this C247 end mill helps you achieve reliable results with clean shoulders, precise slots, and efficient ramping.
