Description
The Dormer Pramet C615 1/4" HSS 4-flute end mill with a flatted Weldon shank is a reliable choice for shoulder milling, slot milling, and ramping. Designed for use in free-machining steel and copper alloys, this regular-length tool delivers consistent, precise cuts with durable performance.
- Diameter: 1/4" (0.250")
- Flutes: 4-flute geometry for strong cutting edges and efficient chip evacuation
- Length of Cut: 5/8" (0.625")
- Overall Length: 2 7/16" (2.4375")
- Shank: 3/8" Weldon shank with a flatted drive surface for secure engagement
- Material & Finish: High-speed steel (HSS) with bright finish for durability and clean cuts
- Helix Angle: 30° for steady cutting in shoulders, slots, and ramping
- Recommended Materials: Free-machining steel, plain carbon steel, and copper or copper alloys

The 4-flute design and 30° helix are optimized to deliver smooth, precise pockets and clean slotting, even when working with tougher free-machining steels. The bright HSS finish resists built-up edge and provides dependable wear resistance across multiple passes. The flatted Weldon shank helps prevent slipping in collets, ensuring consistent engagement and concentric cuts that improve shoulder accuracy and slot dimensions. Ideal for shops performing routine milling tasks, this end mill pairs proven Dormer Pramet reliability with a compact, versatile size that fits a wide range of milling centers.
