Description
The OSG Carbide 5 Flute End Mill Square Edge is a long‑length carbide cutting tool designed for side milling. With an 8 mm diameter, a square edge, and a built‑in chipbreaker, it delivers extended reach up to 4xD and dependable chip control for deep pockets, shoulders, and tight profiles.
Designed for engineers, machinists, tradespeople, and hobbyists who require high performance in demanding milling tasks, this end mill combines precision with reliable operation to handle challenging side milling workouts.
- Long reach for side milling up to 4xD: The extended length enables cutting deep pockets, slots, and profiles without repositioning the workpiece or changing tools.
- Built-in chipbreaker for efficient chip evacuation: Helps break and channel chips away from the cutting edge, reducing jam risk, heat buildup, and edge wear for smoother cuts.
- Five-flute, square-edge geometry: Five flutes provide improved stability and material removal, while the square edge ensures precise corners for demanding side milling tasks.
This combination supports faster setups, cleaner finishes, and reliable performance in challenging applications, helping you finish jobs with consistency and confidence.
