12R3 4 Flute Carbide Corner Rounding End Mill For Stainless Steel High Temp Alloys CNC Milling Cutter

Introduction:

The 12R3 4-Flute Carbide Corner Rounding End Mill is a high-performance cutting tool designed for precision machining of stainless steel, high-temperature alloys, and other tough materials. Featuring a round nose (corner radius) design, this end mill provides excellent surface finish and durability, making it ideal for roughing, semi-finishing, and contouring operations in CNC milling applications.

Features:

✔ 4-Flute Design – Optimized for efficient chip evacuation and smooth cutting performance.

✔ Corner Radius (R3) – Reduces tool wear and prevents chipping while improving edge strength.

✔ Premium Carbide Material – Ensures long tool life and resistance to high heat and abrasion.

✔ High-Performance Coating (optional, if applicable) – Enhances wear resistance and reduces friction.

✔ Stainless Steel & High-Temp Alloy Optimized – Engineered for challenging materials like Inconel, Titanium, and hardened steels.

Advantages:

✅ Extended Tool Life – Carbide construction withstands extreme cutting conditions.

✅ Superior Surface Finish – The rounded edge minimizes burrs and improves part quality.

✅ Versatile Machining – Suitable for roughing, finishing, and profiling in aerospace, automotive, and mold-making industries.

✅ Reduced Vibration – Stable cutting performance even at high speeds.

Applications:

Aerospace – Machining turbine blades, engine components, and structural parts.

Medical & Dental – Precision milling of surgical instruments and implants.

Automotive – Cutting high-strength alloy parts and transmission components.

Mold & Die Making – Smooth contouring and detail work on hardened steels.

General CNC Milling – Ideal for workshops handling tough materials.
