Dormer Pramet C167 6.0mm HSS-E PLAIN Shank 2 Flute Standard Length Slot Drill

The Dormer Pramet C167 6.0mm two‑flute slot drill is a durable HSS‑E cutting tool designed for precise shoulder milling and slot milling in free‑machining steels and copper alloys. With a cobalt‑based composition and a bright finish, it’s built to deliver reliable performance across repetitive milling tasks.

• Diameter: 6.0 mm
• Flutes: 2‑flute design for efficient cutting and smooth chip evacuation
• Length of Cut (LOC): 13 mm for shallow slots and pockets
• Overall Length: 180 mm to reach deep or recessed features
• Shank: 6 mm plain shank for compatibility with common collets and chucks
• Material/Coating: Cobalt‑based HSS‑E with a bright finish for enhanced wear resistance
• Helix & Rake: 30° helix and 12° rake angle optimized for shoulder milling and slot milling
• Applications: Ideal for shoulder milling and slot milling in free machining steel and copper or copper alloys

Designed to tackle slots, pockets, and shoulders with consistent results, this drill offers predictable performance in soft to moderately tough metals. The 2‑flute geometry helps with rapid material removal and clean slot edges, while the cobalt‑enhanced HSS‑E construction stands up to wear during higher‑speed milling. Its long 180 mm reach enables access to deeper features without compromising rigidity, making it a practical choice for machining centers and manual milling setups alike. Whether you’re producing keyways, slots, or shallow pockets in copper alloys or free‑machining steel, the C167 slot drill provides a reliable, repeatable cutting experience that helps you maintain tight tolerances and efficient cycle times.
