Flowtapping is also a chipless operation.  The thread shape is formed through the entire length of the bushing; therefore, a thread length of minimum 1 x D can normally be achieved.  The load of a cold formed thread exceeds that of a standard cut thread and provides a positive lifetime benefit as well.

Theoretically yes - however as a rule, the necessary.

Reasons for not hand drilling:

• Inexact tools admission in the three-jaw chuck
• Necessary spanning force is not sufficient
• Necessary axial force may not be reached
• Necessary speeds / engine power is not sufficient
• Heat is not carried off and can damage the chuck
• Danger of the drill slipping and with it of a breakage by manual axial guidance

In particular as a time and cost saving alternative with at the same time higher quality in comparison, e.g. to the sweat, press and rivet joins or other cut threads.

The most varied application possibilities thereby arise in the whole metal processing industry; everywhere where sheet metals or tins are worked on and processed (see the ADS book).

Typical sectors and application examples:

• Automotive: Thread for O2 sensor in the exhaust systems
• Sanitary: Connection for heater valves systems on manifolds
• Steel furniture: Connection for the plastic roles
• Spray arrangements: Connection of valve bodies
• Facade constructions: Connection of glass holders, handrails and push clutches
• Solar collectors: Brazed connection on capillary

The cooling fan acts as a large heatsink to reduce heat from travelling from the part to the machine spindle during the Flowdrill operation.  The cooling fan is installed on all Flowdrill toolholders.

To reduce the effect of build up material on the tools surface and increase the tool life to its limits.

About every 3 to 4 drillings in steel, with all other materials apply the lubricant before every hole in a thin layer up and down the length of the drill (also see short instruction).
