Description
The OSG Carbide 3 Flute End Mill Square is a regular-length, center-cutting tool designed for general machining tasks. With a 1.5 mm diameter and three-flute geometry, it excels at milling, slotting, and profiling, delivering efficient material removal and precise results across a broad range of materials. This versatile end mill is ideal for engineers, machinists, hobbyists, and maintenance professionals who need dependable performance in everyday milling operations.
Carbide construction provides stiffness and wear resistance for longer tool life and consistent edge quality. The square end and center-cutting geometry support plunging into the work and starting slots cleanly, enabling faster setups and cleaner cuts in both roughing and finishing passes.
- Center-cutting versatility: Center-cutting geometry lets you plunge into the workpiece and start cuts cleanly, speeding setups and improving accuracy.
- Three-flute efficiency: The 3-flute design delivers a strong material-removal rate with a smooth finish and reliable chip evacuation for a wide range of applications.
- Regular-length, general-purpose design: Flexible length accommodates milling, slotting, and profiling across different depths and workholding setups without changing tools.
In practice, this end mill delivers reliable performance across common machining tasks. The carbide construction and optimized flute geometry help maintain consistent cuts, extend tool life, and reduce downtime from tool changes. Its center-cutting capability and compact diameter make it ideal for precise, detail-oriented work while still delivering efficient material removal on larger jobs, helping you complete projects faster with better results.
