3mm-20mm 2 Flute Carbide Drill Bit External Coolant CNC Metal Drill for Steel Titanium

3mm-20mm 2 Flute Carbide Drill Bit External Coolant CNC Metal Drill for Steel Titanium

Introduction:

The 2 Flute Carbide Drill Bit is a high-performance cutting tool designed for precision drilling in hardened steels, titanium alloys, and other tough materials. Featuring a solid carbide construction and external coolant compatibility, this drill delivers exceptional accuracy, extended tool life, and superior chip evacuation in demanding CNC machining applications.

Features:

✔ 2-Flute Design – Optimized for efficient chip evacuation, reducing heat buildup and preventing clogging.

✔ Solid Carbide Material – Provides maximum rigidity and wear resistance, outperforming HSS and cobalt drills.

✔ External Coolant Ready – Compatible with flood or mist coolant systems for improved heat dissipation.

✔ Precision Ground Point – 140° split point for self-centering accuracy and reduced walking.

✔ CNC Optimized – Balanced for high-speed machining with minimal vibration.

✔ Multiple Sizes Available – 3mm to 20mm diameters cover a wide range of applications.

Performance Advantages:

✅ Extended Tool Life – Carbide construction lasts 3-5x longer than HSS in hardened materials.

✅ Superior Hole Quality – Maintains IT8-IT9 tolerances with excellent surface finish (Ra 1.6μm or better).

✅ Faster Cycle Times – High RPM capability reduces drilling time in tough alloys.

✅ Reduced Burring – Sharp cutting edges produce clean hole entry/exit with minimal deburring needed.

✅ Versatile Material Compatibility – Effective in steel (up to HRC 50), titanium, stainless steel, and nickel alloys.

Application:

✔ Titanium Alloys (Grade 5, Ti-6Al-4V)

✔ Stainless Steels (303, 304, 17-4PH)

✔ Tool Steels (D2, H13 up to HRC 50)

✔ Nickel Alloys (Inconel 718, Hastelloy)

✔ Carbon & Alloy Steels
