Polished Carbide Router Bit 16mm 3 Flute End Mill For Aluminum

Introduction:

Our 16mm 3-flute polished carbide end mill is precision-engineered for high-speed CNC machining of aluminum, soft alloys, and non-ferrous metals. Featuring a high-polish flute design and optimized geometry, this end mill delivers superior chip evacuation, minimal built-up edge (BUE), and a flawless mirror-like finish – making it ideal for aerospace, automotive, and precision engineering applications.

Crafted from ultra-fine grain solid carbide, it outperforms standard HSS or coated end mills in tool life, cutting speed, and surface quality.

Features:

✔ 3-Flute Design – Perfect balance for aluminum (better chip clearance than 2-flute, smoother than 4-flute).

✔ High-Polish Flute Surface – Prevents material adhesion and reduces friction.

✔ Optimized Helix Angle (35°-45°) – Enhances chip flow and reduces heat buildup.

✔ Center Cutting – Allows plunge milling, slotting, and contouring.

✔ Precision Ground Edges – Ensures sharp, consistent cuts with minimal burrs.

✔ 16mm Diameter – Ideal for heavy material removal and finishing in one pass.

Advantages Over Competitors

✅ 50% Faster Machining – Higher feed rates due to efficient chip evacuation.

✅ 2X Longer Tool Life – Carbide + polished flutes resist wear and BUE.

✅ Mirror Finish Ready – Reduces or eliminates post-processing (saving time and cost).

✅ Vibration-Free Cutting – Stable performance even at high RPMs (20,000+).
