Meet the Dormer Pramet C273 3/16" HSS-E powder metall end mill—a long-series tool designed for shoulder milling and slot milling in free machining and plain carbon steel as well as copper and copper alloys. With its extended reach and robust build, this 4-flute end mill handles deep pockets and precise slots with consistent performance.

• Diameter: 3/16" (4.76 mm)
• Flutes: 4-flute configuration for efficient material removal and stable cutting
• Length of Cut (LOC): 24 mm
• Overall Length: 68 mm
• Shank: 6 mm Weldon flat shank for secure drive and precise alignment
• Material: HSS-E powder metallurgy with bright finish for improved hardness and wear resistance
• Helix Angle: 30° for smooth chip formation and reduced vibration
• Rake Angle: 12° to enhance cutting action on shoulders and slots
• Standards: DIN 844 L long-series geometry for compatibility with standard holders
• Applications: Ideal for shoulder milling and slot milling in free-machining steel and copper/copper alloys

This end mill is engineered to deliver durable performance in demanding milling tasks. The powder-metallurgical HSS-E construction provides reliable edge retention at cutting speeds common in general-purpose steel and copper alloy workpieces, while the bright finish aids in visibility and heat management. The long length and Weldon shank support deep cavities and precise tool control, making it a practical choice for shops that need dependable, single-tool efficiency for extended milling operations.
