Description
The OSG Carbide 3 Flute Centre Cutting Square Edge End Mill is a precision cutting tool designed for aluminium machining. Its short length design offers rigidity and precise control in tight pockets and setups.
With three flutes and centre cutting, square-edge geometry, this end mill delivers efficient material removal and stable performance across aluminium applications, from prototype work to production parts.
- Three-flute centre-cutting design: Enables fast material removal and reliable plunging in aluminium, helping you achieve consistent slotting and profiling with fewer passes.
- Short length for tight access: Increases rigidity and reduces deflection and chatter in confined pockets, resulting in cleaner edges and better surface finish.
- Carbide construction for aluminium: Delivers long tool life with excellent wear resistance, maintaining accurate dimensions and stable performance across repeated cuts.
Designed for engineers, machinists, buyers, tradespeople, hobbyists, and non-technical customers alike, this end mill helps you complete aluminium projects faster with predictable results. The combination of rigidity, quality carbide, and precise geometry reduces downtime, improves finish quality, and supports tighter tolerances—giving you confidence in every part you manufacture.
