Description
The OSG Carbide 3 Flute End Mill with a corner radius and DLC coating is a precision machining tool designed for aluminum. With three flutes and a dedicated corner radius, it efficiently removes material while maintaining stability and accuracy. The DLC coating enhances tool longevity and wear resistance, making it a reliable choice for demanding aluminum machining tasks.
- DLC-Coated for Extended Tool Life: The Diamond-Like Carbon coating dramatically improves wear resistance, helping resist built-up edge and reducing how often you need to replace the tool.
- Three-Flute Design for Efficient Material Removal: The three-flute geometry delivers steady cutting action and effective chip evacuation, promoting smoother, more consistent cuts in aluminum.
- 20 mm Diameter with R1.25 Corner Radius for Precise Finishes: The 20 mm size and narrow corner radius enable accurate contouring and clean radii, improving part finish and dimensional control on aluminum workpieces.
This end mill is a practical choice for engineers, machinists, and hobbyists who demand reliable performance in aluminum. Its combination of a robust carbide core, DLC durability, and a precisely engineered corner radius helps you complete tasks with fewer tool changes, less rework, and consistently high-quality surfaces.
