The Dormer Pramet C247 1/2 inch HSS-E powder-metallurgical end mill is a reliable, high-precision tool designed for shoulder milling, slot milling, and ramping. Built to DIN 844 K with a 12 mm Weldon shank, it delivers consistent performance in free‑machining steels and copper alloys where edge integrity matters.

• Diameter and flute count: 1/2" diameter with a 4-flute design for efficient material removal.
• Length of cut: 26 mm length of cut (LOC) for controlled engagement in pockets and shoulders.
• Overall length and reach: 83 mm overall length with a 37.5 mm reach and neck relief for access to tight pockets.
• Shank and standard: 12 mm Weldon shank; DIN 844 K standard for secure, repeatable toolholding.
• Material and finish: Powder-metallurgical HSS-E with bright finish for improved wear resistance and smoother cutting action.
• Geometry: 30° helix and 12° rake angle optimized for shoulder milling, slot milling, and ramping applications.
• Applications/materials: Suitable for free machining and plain carbon steel and copper or copper alloys, delivering consistent performance in these materials.

This end mill delivers dependable performance across a range of milling tasks. The four-flute design balances rapid material removal with a good surface finish, while the powder-metallurgical HSS-E substrate provides enhanced wear resistance and toughness for longer tool life. The 30° helix supports efficient chip evacuation and smoother cuts, reducing heat buildup and improving edge retention. With DIN 844 K compatibility and a sturdy Weldon shank, you get reliable clamping and repeatable results in standard tooling setups. The generous reach and neck relief enable precise profiling in pockets and shoulders, making it a practical choice for production work in free-machining steels and copper alloys where consistent geometry matters.
