Dormer Pramet C159 5.0mm HSS-E Flatted Shank 2 Flute Standard Length Slot Drill DIN 844 K

Engineered for precision slot and shoulder milling in non-ferrous metals, the Dormer Pramet C159 5.0 mm HSS-E slot drill delivers reliable, consistent cutting performance in a compact standard-length design.

• Diameter: 5.0 mm
• Length of cut: 13 mm
• Overall length: 57 mm
• Shank: Weldon, 6 mm
• Material: HSS-E (cobalt-based) with bright finish
• Flutes: 2
• Helix angle: 40°
• Rake angle: 20°
• Standards: DIN 844 K
• Applications: shoulder milling, slot milling, and ramping in non-ferrous metals

This 2-flute drill combines the toughness of cobalt-based HSS-E with a bright finish for smoother cutting and better heat resistance. The 40° helix directs chips efficiently from the cut, while the 20° rake angle helps maintain a clean, precise slot and reduces cutting forces during ramping and shoulder operations. The Weldon 6 mm shank provides a secure, repeatable clamping interface for reliable performance in demanding setups. Ideal for aluminum, brass, and other non-ferrous alloys, this tool excels at creating accurate slots, pockets, and keyways with minimal deflection.
