Description
The OSG Carbide 4 Flute End Mill Square, Regular Length Centre Cutting, is a versatile carbide milling tool built for general machining tasks. With a 3 mm diameter and four cutting edges, it handles milling, slotting, and profiling with consistent precision. Its regular-length, centre-cutting design provides stable performance across a wide range of materials and applications, making it a reliable choice for both professional shops and DIY setups.
- Four-flute square-end geometry: balances rigidity and chip evacuation to deliver smooth, efficient material removal on general milling, slots, and profiles.
- Centre-cutting utility: enables plunging cuts and versatile contouring without repositioning, expanding your capabilities in pocketing, milling, and edge work.
- Carbide construction for durability: high-hardness carbide resists wear for longer tool life and consistent results, reducing tool change frequency and downtime.
Designed for reliable, repeatable results, this 3 mm end mill helps you achieve precise features and clean finishes with fewer passes. The combination of its square end, four cutting edges, and durable carbide makes it well-suited for everyday machining tasks in metal or plastic, giving you confidence to complete projects efficiently and with professional-quality results.
