Friction Drill Bit: High-Efficiency Hole Forming with DUOMI Thermal Drilling Technology
In the era of lightweight metal fabrication and high-precision assembly, the friction drill bit has emerged as a revolutionary tool that redefines how holes are formed in thin-walled metal tubing. Unlike conventional drilling tools that rely on cutting and material removal, a friction drill bit utilizes heat generated by friction to plastically deform the material and create a clean, high-strength hole without chips or the need for auxiliary fasteners. Among global manufacturers, DUOMI stands out as a trusted innovator in friction drilling solutions, offering durable and performance-driven thermal friction drill bits for industrial applications.
What is a Friction Drill Bit?
A friction drill bit, also known as a thermal drilling bit or heat friction bit, is a conical, high-speed rotating tool made of wear-resistant materials such as tungsten carbide. It generates intense frictional heat upon contact with a metal surface, softening and displacing the material to form a hole along with an extruded collar or bushing. This process enables strong, threadable connections in metals as thin as 1.0 mm, making it an ideal solution for automotive, electric vehicle (EV), furniture, and HVAC manufacturing industries.
Key Features of Friction Drill Bits:
Chipless operation (no metal shavings)
Integrated bushing formation for threading
Applicable to steel, stainless steel, aluminum, brass, and copper
Fast cycle times ideal for automated production
No pre-drilling or post-welding required
