Description
The OSG Carbide 4 Flute End Mill Square, 3mm diameter, is a long-length, center-cutting milling tool crafted for a wide range of general machining tasks. It’s built to deliver dependable performance in workshops, job shops, and home setups, making it a practical choice for engineers, buyers, and hobbyists who need a versatile, reliable end mill.
With its extended reach, this end mill can access deep slots and hard‑to‑reach work areas while maintaining cutting efficiency and consistent results. The four-flute design supports steady material removal and helps you maintain accurate paths, whether you’re milling profiles, slots, or flat surfaces.
- Long Reach for Deep Work: Extended length allows access to deep pockets and complex geometries without losing rigidity or precision, enabling more versatile setups and fewer tool changes.
- Four Flutes for Efficient Cutting: Higher material removal rate with a smoother finish and reliable chip evacuation, reducing heat build‑up and improving tool life in busy production or prototype runs.
- Center-Cutting Square End: Square cutting edge provides true plunging and accurate 90° corners, making it ideal for milling, slotting, and profiling across a wide range of materials and machines.
This end mill combines carbide durability, extended reach, and versatile cutting geometry to help you complete jobs with confidence. It supports consistent performance across general machining tasks, helping to shorten cycle times, reduce downtime, and produce clean, accurate features from roughing to finishing.
