Description
The OSG Carbide 3 Flute End Mill Square is TiAlN coated, regular-length, center-cutting and sized at 18 mm in diameter for general machining tasks such as milling, slotting and profiling. With three flutes and a square end, it delivers reliable corner accuracy and consistent finishes across a wide range of materials.
- TiAlN coating for extended tool life: The TiAlN coating provides wear resistance and heat stability, helping you maintain cutting performance and reduce tool changes in demanding jobs.
- Three-flute design for fast, clean material removal: Three cutting edges balance chip evacuation and surface finish, enabling efficient milling across a variety of materials.
- Regular-length center-cutting square end for versatility: Regular length offers balanced rigidity for everyday use, while center-cutting and a square end support plunging, profiling, and precise 90-degree corners in general machining tasks.
This end mill is designed to streamline your workflow: it delivers dependable results, reduces downtime from tool changes, and supports consistent, precise cuts across milling, slotting, and profiling tasks. The combination of TiAlN wear resistance, a stable three-flute geometry, and a versatile regular-length, center-cutting square end makes it a reliable choice for engineers, machinists, hobbyists, and fabricators working on general machining projects.
