ITC Carbide End Mill Square Edge 4204 - 4 Flute 45° Helix Chipbreaker - Non-Ferrous - 20mm

The ITC Carbide End Mill Square Edge 4204 is a high-performance cutting tool designed for non-ferrous metals. With a 20 mm diameter and a square-edged tip, it delivers clean, precise cuts on aluminum, brass, copper, and similar alloys. This versatility makes it a reliable choice for engineers, machinists, hobbyists, and shops seeking consistent results across a range of projects.

Built for stability and efficiency, this end mill features a 4-flute design, a 45° helix, and integrated chipbreakers. The combination enhances chip evacuation and cutting stability, helping you maintain tight tolerances and finish quality even when removing material quickly.

• 4-Flute Design for Stability: Four flutes provide greater rigidity and efficient chip clearance, enabling higher feed rates on non-ferrous materials while preserving precision and surface finish.
• 45° Helix with Chipbreakers: The 45-degree helix paired with chipbreakers breaks and evacuates chips effectively, reducing cutting forces and heat for smoother cuts and longer tool life.
• Square Edge for Precision: Square-edged geometry delivers crisp corners and accurate edges, reducing deburring needs and ensuring repeatable results in pockets and slots.

Whether you’re prototyping, performing repetitive production work, or tackling demanding non-ferrous machining, the ITC 4204 end mill helps you finish faster with reliable outcomes. Its carbide construction stands up to production workloads, while the engineered geometry supports consistent performance, reduced downtime, and higher quality finishes across a range of non-ferrous applications.
