2 Flute Coolant Through Drill for Aluminum High Speed CNC Carbide Drill Bit with Internal Coolant Channels Precision Hole Making Tool

Introduction:

The 2 Flute Coolant Through Drill is a high-performance carbide drill bit specifically engineered for precision drilling in aluminum and non-ferrous metals. Featuring internal coolant channels and an optimized 2-flute design, this drill delivers exceptional chip evacuation, reduced heat buildup, and extended tool life in high-speed CNC machining applications.

Features:

✔ 2-Flute Geometry – Provides excellent chip evacuation, preventing clogging in deep-hole drilling.

✔ Internal Coolant Channels – Directs high-pressure coolant (up to 70 bar) to the cutting edge, reducing heat and extending tool life.

✔ Carbide Substrate – Ultra-fine grain carbide ensures durability and wear resistance in high-speed operations.

✔ Aluminum-Optimized Design – Special rake angle and polished flutes minimize material adhesion (BUE).

✔ High-Speed Machining (HSM) Ready – Stable performance at 20,000+ RPM (varies by diameter).

✔ Precision Ground Tip – Self-centering geometry for accurate hole positioning (±0.01mm tolerance).

Advantages:

✅ 3–5× Longer Tool Life – Carbide + coolant reduces wear vs. standard drills.

✅ Faster Cycle Times – Optimized for high-speed peck drilling in aluminum (up to 3× faster than HSS).

✅ Superior Hole Quality – Achieves IT8–IT9 tolerance with Ra 0.8–1.6μm surface finish.

✅ Deep-Hole Capable – Stable performance up to 10× diameter depth (with coolant support).

✅ Reduced Burrs – Sharp cutting edges produce cleaner hole exits.
