Design

Flowdrill tools are molded and shaped from very high strength tungsten carbide. The forming part of the tool has a polygonal shape with four facets. These facets produce the friction while turning at high speeds to heat and form the material. Flowdrills are designed with an almost flat conical tip that transitions into a sharper conical shape that leads into the cylindrical shape. The conical and cylindrical portions of the tool are polygon shaped. The cylindrical part of the tool determines the diameter of the hole.

Several styles and sizes are available to suit your Flowdrilling needs. Sizes and styles can also be customized.

 

 


 

Standard

The Standard Flowdrill will produce a hole with a ring around its collar. This ring or collar is formed from the displaced material that flows towards the upper surface.
The Standard type comes in a Short or a Long version. The Short or Long versions are chosen according to the material thickness .

 

Flat

The Flat Flowdrill cuts the collar formed on the upper surface of the material. This is used when specifications call for a flat joining surface. Short or Long versions are chosen according to the material thickness.

 
 
 

REM

All Flowdrill tools can be supplied with this feature which uses a fluted tip to remove any material coverings such as paint, anodizing coatings, or any other special coverings that may hinder the initial Flowdrilling process. Perforating the material is easier using this fluted point. Using a Rem point axial force can be reduced making this suitable for materials that may dent due to their minimal thickness or lack of rigidity.

   

Special

Any of these styles can be customized to meet your specific needs. We will gladly review your material specifications along with the required tolerances to design a Special type of Flowdrill for your specific application.


 
 
The following are examples of Special types of Flowdrills:
  • Super Long. This Flowdrill is utilized when the material thickness or special circumstances require a longer cylindrical geometry.

  • Super Short. This Flowdrill is utilized when the material thickness or special tolerances (i.e. within a pipe) require a shorter cylindrical geometry.
  • Special radius for the top of the Flowdrill. The top of the cylindrical part can be modified to control the shape of the formed collar or to create a countersunk hole.
  • Special Angle for the Flowdrill Flat. The standard Flat type has cutting edges with a 5 angle from the horizontal plane. This angle can be increased to create a chamfer around the hole.
