Izar 9439 — Mirror-Polished Aluminium Endmill (3-Flute, 45° Helix, DIN 6528 N)

The Izar 9439 is a high-performance solid carb­ide endmill, engineered from micro-grain carbide with a mirror-polished finish, crafted exclusively for aluminium and non-ferrous machining. Featuring 3 flutes and a 45° helix, this cutter offers superior chip evacuation, reduced build-up, and unmatched surface finishes even under aggressive spindle speeds.

Geometry & Benefits

• Mirror-polished flutes: Minimal surface adhesion and smoother chip flow, preventing built-up edge and improving finish quality.

• 3-flute geometry: Ideal for soft, ductile materials—enhances rigidity while maximizing flute space for chip clearance.

• 45° helix angle: Cuts smoothly with reduced cutting forces and cleaner surfaces.

• Micro-grain carbide: Provides strength and wear resistance required for high-speed aluminium work.

• DIN 6528 N compliance: Ensures reliable, repeatable performance in production environments.

Applications & Advantageous Uses

• High-speed slotting, profiling, and finishing in aluminium alloys (non-alloyed and Al-Mg Si up to >10%).

• Non-ferrous materials: Ideal for copper, brass, bronze, and magnesium alloys.

• Precision work: Molds, fixtures, and parts where surface quality and productivity are paramount.

• Production environments: Particularly in CNC setups with high spindle speeds and frequent tool changes.
