Understanding Flow Drill Technology: Precision, Efficiency & Industrial Applications

Flow drill, also known as thermal drilling or flow drilling, is an advanced, chipless method of creating holes in thin metal materials without the need for tapping or welding. The process uses heat and pressure to displace material and form a bushing, which is ideal for thread forming or structural strength in metalworking applications. This technique is highly efficient, precise, and cost-effective — making it popular in various industries like automotive, aerospace, manufacturing, and fabrication.

How Does Flow Drilling Work?
Flow drilling involves a specially designed conical drill bit made from solid carbide or tungsten. When the rotating bit is applied to a metal surface, frictional heat softens the material. Instead of removing the material, the tool pushes it downward and forms a collar or boss around the hole. This displaced material increases the thickness of the hole, allowing for stronger threads and a more secure hold for fasteners.

Key Advantages of Flow Drill Technology

1. No Material Waste: As it’s a chinless process, there’s minimal waste generation, making it environmentally friendly.
2. Increased Strength: The formed collar reinforces the hole, allowing threads to hold stronger even in thin materials.
3. Time & Cost Efficient: Flow drilling eliminates secondary operations like welding nuts or using inserts, reducing production time and cost.
4. Versatile: It can be used on a variety of materials including steel, stainless steel, aluminum, copper, and brass.

• Automotive chassis and frame construction
• HVAC duct systems
• Electrical enclosures and switchgear components
