Friction drilling enables fast, precise, and durable thread creation in thin materials, directly on your CNC machine. By forming, not cutting, the material, Flowdrill creates a strong, integral bush that provides several times more thread length than the base material thickness.
On vertical machining centers (VMC’s) and other CNC setups, friction drilling offers a clean, efficient process for structural and high-load applications.
Key advantages:

Each combination of material and thread size requires a specific CNC program to ensure smooth forming and consistent hole quality.
Provide us with:
We will supply a custom program with the correct spindle speed, feed stages, and cycle time, so you can start right the first time.
For friction drilling and tapping an M8 thread in mild steel (2 mm wall thickness), a Flowdrill tool running at 2180 RPM with programmed feed stages completes the cycle in 2.9 seconds.
