Durable and precise, the Dormer Pramet C11 9/16 Inch HSS-E-Powder Metallurgical Slot Drill is engineered for slot milling, shoulder milling, and ramping in free machining steel and copper alloys. Its extra-short series and Weldon shank deliver rigidity in tight slots for accurate, repeatable results.

• Diameter: 9/16" (14.29 mm) slot drill designed for precise pockets and slots
• Flutes: 2-flute configuration for efficient chip removal and a smooth cut
• Length of Cut: 16 mm to match compact milling needs without sacrificing stability
• Overall Length: 73 mm for controlled reach in limited-access areas
• Reach with Neck Relief: 27.5 mm to improve access while maintaining rigidity
• Shank: Weldon 12 mm for secure clamping and reduced runout during milling
• Material: HSS-E with powder metallurgical production and bright finish for wear resistance
• Helix: 30° helix to promote smooth cutting action and efficient chip evacuation
• Rake Angle: 12° to support effective cutting in shoulder and slot milling
• Standard: DIN 327 D compliance ensures reliable interchangeability with compatible tooling systems
• Applications: Suitable for shoulder milling, slot milling, and ramping in free machining steel and copper alloys

This slot drill is optimized to deliver clean slots and precise shoulders with minimal deflection, thanks to its rugged short-series design and reinforced HSS-E powder metallurgy core. The bright finish aids chip control and longevity when working with copper alloys, while the 30° helix and 12° rake angle balance cutting forces for stable operations. With a compact 16 mm cutting length and a 73 mm overall length, it reaches tight pockets without compromising rigidity, making it a reliable choice for production environments that demand repeatable slotting performance and durable edge retention.
