The Dormer Pramet C122 22.0mm HSS-E PLAIN Shank 2 Flute Extra Long Slot Drill is a purpose-built end mill for deep-slot and shoulder milling in metalworking. Designed for free-machining steel and copper alloys, it delivers reliable performance with a long reach.

• Diameter: 22 mm
• Length of Cut (LOC): 75 mm
• Overall Length: 170 mm
• Reach with Neck Relief: 90.5 mm
• Shank: 20 mm plain
• Material: HSS-E (cobalt-based) with bright finish
• Flutes: 2
• Helix Angle: 30°
• Rake Angle: 12°
• Series: Extra Long
• Primary Applications: Shoulder milling and slot milling in free machining steel and copper/copper alloys

Equipped for challenging, deep-cut operations, this tool enables efficient slotting and shoulder milling in tight cavities without frequent tool changes. The cobalt-enriched HSS-E alloy maintains cutting edge integrity under higher temperatures, while the 30° helix promotes steady chip evacuation and smoother cutting action. The bright finish reduces built-up edge, helping achieve cleaner surfaces in copper alloys and free-machining steels. With a 20 mm plain shank, it aligns with common milling setups, giving you dependable compatibility across standard collets and holders.
