Through Coolant Carbide Metal Drill Bit Tungsten Reamer Drill Bits 12mm

Through coolant carbide metal drill bit 12mm tungsten carbide reamer drill bits

The AMG 12mm Tungsten Carbide Reamer Drill Bit is a high-precision, through-coolant cutting tool designed for accurate hole finishing, reaming, and drilling in hard metals. Featuring a solid carbide construction and coolant-through channels, it ensures efficient heat dissipation, extended tool life, and superior surface finish in demanding machining applications.

Key Features:

1. Solid Tungsten Carbide Construction

• Extreme Hardness & Wear Resistance – Ideal for drilling hardened steels, stainless steel, cast iron, and superalloys (Inconel, titanium).

• Longer Tool Life – Outperforms HSS and cobalt drills in high-speed, high-feed operations.

2. Through-Coolant Design (Internal Coolant Holes)

• Efficient Heat & Chip Evacuation – Directs coolant to the cutting edge, reducing thermal deformation and workpiece hardening.

• Improved Surface Finish – Prevents built-up edge (BUE) and ensures smoother, burr-free holes.

• Supports High-Speed Machining (HSM) – Enables higher RPM & feed rates without overheating.

3. Precision Reamer-Style Geometry

• Multi-Flute Design (Typically 4-6 Flutes) – Enhances finishing accuracy and hole roundness (tolerances within H7/H8).

• Sharp Cutting Edges – Minimizes cutting forces while maintaining dimensional stability.

• Self-Centering Point – Reduces walking for straight, true-to-size holes.

4. Advanced Coating Options (Optional)

• TiAlN (Titanium Aluminum Nitride) – Best for high-heat applications (up to 900°C).

• TiCN (Titanium Carbo-Nitride) – Improves abrasion resistance in stainless steel.

• Diamond-Like Carbon (DLC) – For non-ferrous metals (aluminum, copper).

5. Heavy-Duty Applications

✔ CNC machining centers & lathes
✔ Precision hole reaming & finishing (automotive, aerospace, mold-making)
✔ Deep-hole drilling with coolant support
✔ High-volume production in hardened materials

Applications:

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

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