3 Flutes Solid Carbide Twist Drill 50mm - 300mm Heavy Duty Drill Bit

3 Flutes Heavy Duty Solid Carbide Twist Drill Bits For Drilling Metal Iron Nano-TiXCo coating

3-flute heavy-duty solid carbide twist drill bits are high-performance cutting tools designed for precision drilling in hard metals, alloys, and tough materials. Their unique 3-flute geometry enhances chip evacuation, reduces heat buildup, and improves drilling speed compared to traditional 2-flute drills. Made from solid tungsten carbide and often enhanced with advanced coatings (like Nano-TiXCo, TiAlN, or TiCN), these drill bits are built for industrial-grade durability and efficiency.

Key Features:

1. 3-Flute Design:

Provides higher cutting efficiency and better chip evacuation compared to standard 2-flute drills, reducing heat buildup.

Ideal for hard metals (iron, steel, alloys) and high-speed applications.

2. Solid Carbide Construction:

Made from high-grade tungsten carbide for extreme hardness, wear resistance, and durability.

Maintains sharpness longer than HSS (High-Speed Steel) drills.

3. Nano-TiXCo Coating:

Advanced nanostructured titanium-based coating that enhances:

Heat resistance (reduces friction and overheating).

Lubricity (smoother cutting action).

Tool lifespan (resists wear and oxidation).

4. Heavy-Duty Performance:

Optimized for rigorous industrial use in CNC machines, drill presses, and hand-held drills.

Suitable for deep-hole drilling in tough materials.

5. Precision Ground Geometry:

Self-centering point reduces walking and improves accuracy.

Aggressive cutting edges ensure fast, clean holes

Applications:

Drilling hard metals: iron, steel, stainless steel, cast iron, and titanium alloys.

Used in automotive, aerospace, machining, and metal fabrication.
