Flow drills(N1150)

 Flow drills(form drills), solid carbide,
 

The flow drill comes into contact with the material using relatively high axial pressure and
rational speed. The generated heat makes the material soft and mealleable enough to be formed
or perforated. As the flow drills push into the material, some of the displaced material forms a
collar around the upper surface of the workpiece. The rest of the material froms a bushing in the
lower surface of the workpiece. All this happens in a matter of seconds. The resulting collar and
bushing can be up to 3 times the original material thickness. The diamter of the bush is accurately
determined by the cylindrical part of the flow drill tool. The process does not disturb the material's
internal structure. As a result, the formed bush is remarkably strong and can be used for bearing
sleeves or, when threaded in a separate process, can provide high torque threaded surfaces with
very high pull out strength specifications.

Applications:
The flow drill process can be used in any application where the material thickness does not
provide support for a threaded surface or a sleeve bearing application. When you need a welded
or revited nut or a special insert,---think flow drill. You will improve quality and save a lot of money.
Flow drill tools can be used on standard drilling machines, NC or CNC systems with motor
capacities from 1.5 to 3.5 kw. Revolution speeds(RPM) required range from 1000 to 3500 RPM
