A Flowdrill is a lobed, conical tungsten carbide tool. When rotated at high speed and pressed with high axial force into sheet metal or thin walled tube, generated heat softens the metal and allows the drill to feed forward, to produce a hole and simultaneously form a bushing from the displaced material.

There are numerous possible applications for Flowdrill; it increases effective wall thickness for threaded connections or soldered joints etc.

Uses:

• Chipless drilled hole for spraying appliances. No chips, no broken drills.
• Gas tight connections.
• Threaded connection with rim around hole.
• Threaded connection. (Flat face).
• Bearing or shaft support.
• Water tight + soldering high pressure.
