Izar 8400 — Solid Carbide CNC Drill (DIN 6537 K, 2-Flute, 3×D, CROMAX) 1mm - 6mm

The Izar 8400 is a premium solid carbide twist drill, crafted from micro-grain carbide with a CROMAX surface coating. Built to DIN 6537 K standards, this 2-flute, 3×D drill delivers exceptional rigidity, chip evacuation, and precision drilling—ideal for high-performance CNC applications across a broad spectrum of materials.

Geometry & Benefits

• Solid micro-grain carbide: Offers superior hardness, stiffness, and wear resistance—delivering high tool life even at aggressive cutting speeds typical of CNC machining.

• DIN 6537 K / 3×D length: Optimized for typical CNC applications—providing enough reach for most hole depths while maintaining tool rigidity and minimizing breakout and deflection.

• 2-flute geometry: Offers excellent chip clearance and effective cooling, especially helpful in tougher materials and high-speed conditions.

• 140° split point angle: Acts as a self-centering geometry, requiring minimal pilot drilling and reducing walking—great for precise hole placement and productivity.

• CROMAX coating: Reduces friction, lowers cutting heat, and increases wear life—perfectly suited for drilling alloyed and heat-treatable steels as well as stainless and cast iron materials

Typical Uses & Applications

• CNC drilling with high spindle speeds in production environments—designed for tough cycle demands.

• Works effectively on a broad selection of materials:

  • Aluminum-Magnesium alloys (e.g., Al-Mg Si) — 80–300 m/min cutting speed.

  • Construction/carbon steel (<250 HB) — feed: ~0.290 mm/rev, speed: 90–110 m/min.

  • Alloyed & heat-treatable steels — feed: 0.100–0.160 mm/rev, speed: 40–80 m/min.

  • Stainless and cast iron variants also supported with adjusted feed/speed values.

• Ideal when precise, repeatable holemaking is needed with minimal tool wear—and when jobs involve mixed materials from soft non-ferrous to hardened steels.
