Flow Drill: The Advanced Technology for High-Strength Connections
Flow drill’s ability to Increase material thickness, with friction drilling, in copper and stainless steel is a major plus point for the heating, ventilation and air conditioning sector and allows our customers to reduce leaks, improve soldering and support the use of gas type threads.

Introduction to Flow Drilling
Flow drilling, also known as thermal drilling, is an advanced machining process used to create strong, wear-resistant holes in metal materials. This method is widely used in industries requiring high-strength connections, such as automotive, aerospace, construction, and manufacturing.
How Flow Drilling Works
Flow drilling involves the use of a specialized conical drill bit, often made of tungsten carbide, which rotates at high speeds while applying pressure to a metal surface. The frictional heat generated softens the material, allowing the bit to penetrate and form a bushing without removing any material. This results in an extended, reinforced hole ideal for threading or fastening components.
Benefits of Flow Drilling
- Increased Strength — The process forms a bushing, providing additional material thickness that enhances the load-bearing capacity.
- Material Conservation — Unlike traditional drilling, flow drilling does not produce waste chips, making it an eco-friendly process.
- Improved Thread Engagement — The extended bushing allows for stronger threading, reducing the risk of thread stripping.
- High-Speed Processing — The process is quick and efficient, making it suitable for mass production.
- Versatile Application — Works on a variety of materials including steel, aluminum, copper, and brass.
Applications of Flow Drilling
Flow drilling is widely used in industries that require secure and long-lasting fastening solutions. Some common applications include:
- Automotive Manufacturing — Used in car frames and engine components to ensure durable connections.
- Aerospace Engineering — Essential for lightweight and high-strength structures.
- Construction — Applied in steel frameworks, railings, and scaffolding.
- Furniture Production — Ensures strong joints in metal furniture designs.
Conclusion
Flow drilling is a revolutionary technique that enhances the durability and strength of metal connections. By eliminating material waste and creating reinforced bushings, this method has become a preferred choice in various high-performance industries. As technology advances, flow drilling continues to evolve, providing even more efficient and sustainable solutions for modern manufacturing challenges.
