Corporate Advantages
Engineered for the Toughest Environments
Evergreen Carbide combines German precision with innovative materials to deliver unmatched drilling performance.
Premium Raw Materials
We exclusively use sub-micron grain tungsten carbide, providing an optimal balance of hardness and toughness. This ensures our drills maintain a sharp cutting edge even under extreme thermal stress.
Advanced Grinding & Precision
Utilizing state-of-the-art CNC grinding machines, we achieve H6 shank tolerances and exceptional surface finishes. Our meticulous quality control ensures every drill meets concentricity standards within microns.
Innovative Coating Technology
Our proprietary TiAlN and nACo coatings reduce friction and enhance heat resistance, allowing for higher cutting speeds and significantly extending tool life compared to standard market alternatives.
Tailored Engineering Solutions
With an in-house R&D team, we don't just sell tools; we solve problems. From non-standard diameters to complex step-drill geometries, we provide OEM/ODM services tailored to your specific machining environment.
Product Categories
Specialized Solutions for Every Application
Our comprehensive range of drills is designed to meet the most demanding industrial requirements.
Internal Cooling Series
Drill With Coolant
Optimized for high-speed, deep-hole drilling. The internal coolant flow directly reaches the cutting edge, effectively flushing out chips and preventing heat buildup.
Best For
Deep-hole machining (5D, 8D, 12D+), stainless steel, and high-temperature alloys.
Solid Carbide Series
Drill Without Coolant
Offers maximum structural rigidity and stability. It is the most cost-effective solution for shallow holes and general-purpose drilling where external cooling is sufficient.
Best For
Short-hole drilling, stable machining centers, and versatile use across carbon steel.
Precision Positioning
Center Drill
Engineered to create perfect starting holes. It eliminates 'walking' or deflection of the main drill, ensuring that the subsequent drilling process is perfectly aligned.
Best For
Lathe work, precision hole positioning, and high-accuracy machining foundations.
High-Speed Steel Series
HSS Drill
Excellent toughness and resistance to breakage. Unlike carbide, HSS can withstand vibration and less stable machining environments (like handheld drills) without chipping.
Best For
Manual drilling operations, maintenance work, and machining softer materials where cost-per-hole is a priority.
Specialized Solutions
Other Drill Bits
Designed to perform multiple operations in a single pass (e.g., drilling and chamfering), drastically reducing tool change time and increasing production throughput.
Best For
Multi-functional machining, specialized automotive components, and unique aerospace fastener holes.
Application & Materials
Trusted Across Precision-Critical Industries
Our carbide drilling solutions are trusted across industries where precision is non-negotiable. Whether you are working with Hardened Steel, Aerospace-grade Titanium, or Abrasive Cast Iron, Evergreen Carbide has a specialized geometry to optimize your cycle times.
