Carbide drill bits

High-Performance Solid Carbide Drill Bits

Dohre provides a complete range of solid carbide drill bits engineered for high accuracy, smooth chip evacuation, and long tool life. Made from premium micro-grain carbide and processed with advanced CNC grinding, our drills maintain stability and clean hole quality under high-speed and continuous cutting conditions. From standard drills to micro-diameter, deep-hole, and step designs, every tool ensures reliable performance across demanding production environments.

Engineered for Multiple Materials

Dohre carbide drills perform consistently across carbon steel, alloy steel, stainless steel, aluminum, titanium alloys, and composite materials. Their optimized cutting geometry reduces heat, minimizes wear, and maintains stable dimensional accuracy—even in hard-to-machine materials—making them suitable for both precision parts and large-volume industrial production.

Advanced Features

Our drills use ultra-fine carbide, heat-resistant coatings, and polished flutes that improve chip flow, extend tool life, and ensure smooth entry and exit of holes. Precision-ground cutting edges reduce burrs, enable accurate self-centering, and support stable drilling at high spindle speeds, delivering excellent surface quality and reduced machining time.

Drill Bit FAQ

What materials can Dohre drills cut?

Our drill bits are suitable for steel, stainless steel, aluminum, titanium, composites, and plastics.

Can I get custom size drill bits?

Yes, we provide OEM & ODM services for step drills, micro drills, and other customized tools.

How do your drills perform in high-speed machining?

They are designed for stable chip evacuation, reduced heat, and longer tool life at high RPM.

Do you supply drills in bulk for distributors?

Yes, with monthly capacity exceeding 500,000 pcs, we can supply both large orders and small batches.

What are the advantages of carbide drill bits compared to HSS drill bits?

Carbide drill bits offer superior hardness, wear resistance, and heat resistance. They maintain sharp cutting edges longer and provide higher cutting speeds, making them ideal for machining hardened steel, stainless steel, and other tough materials.

Can carbide drill bits be used on all materials?

While carbide drill bits are excellent for metals like hardened steel, cast iron, and stainless steel, they are not recommended for soft materials such as wood or plastics, as their brittleness may cause chipping.
