Magnum 1/2 Inch 4 Flute HSS End Mill (EM12)
Maintain tight tolerances during general-purpose profiling by reducing the tool deflection that leads to scrapped parts. The Magnum 1/2 Inch 4 Flute HSS End Mill is a foundational shop tool, providing high core strength that resists bending under the side loads of finishing passes. Precision-ground from High-Speed Steel, this end mill ensures consistent cutting performance and cleaner surface finishes across a wide range of materials, including mild steel, cast iron, and industrial plastics.
Features
- 4-Flute design - provides high core rigidity to counteract deflection during deep wall profiling.
- Precision-ground flutes - reduces friction and prevents material welding for cleaner finishes.
- Versatile HSS substrate - optimized for a wide range of spindle speeds in steels, alloys, and plastics.
