Dormer Pramet C601 1 x 1 Inch HSS Flatted Shank 2 Flute Slot Drill Regular Length is a compact, versatile end mill engineered for shoulder milling, slot milling, and ramping in free-machining steel. With a 1" diameter and a flat-shank design, it delivers secure seating in standard tool holders while delivering reliable, clean cuts in a regular-length form.

• Diameter and flute count: 1" diameter with 2 flutes for efficient slotting and chip evacuation.
• Shank design: Flatted 1" shank for secure grip and repeatable seating in chucks and collets.
• Material and finish: High-speed steel (HSS) with a bright finish for durability and easy observation of wear.
• Length specifications: 1-5/8" length of cut (DOC) and 4-1/2" overall length; ANSI standard shank interface.
• Helix angle: 30° helix designed to optimize cutting action in steel and improve chip removal.
• Applications: Ideal for shoulder milling, slot milling, and ramping in free-machining steel, delivering stable cuts across multiple passes.

This tool is designed to balance performance and versatility: the two-flute geometry provides good rigidity and chip clearance at moderate feeds, while the HSS core resists wear under repeated use. The combination of a 30° helix and a flat shank helps you achieve consistent depth control, clean slotting, and longer tool life in everyday workshop workflows.
