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.
