Detailed Product Description

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.
