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.
