Product Description

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

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

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

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

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)

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 industries.
