"Special" Fdrill tools can be produced according to the customers needs . Our technical team can assist with all testing and analysis needed.
The following are examples of Special types of Fdrills:
1.REM
All Flowdrill tools can be supplied with a REM which uses a fluted tip to remove coatings or layers which may hinder the initial Flowdrilling process such as:Paint,Zinc plating,Anodizing.
A Rem point can also reduce axial force making this suitable for materials that may dent due to their minimal thickness or lack of rigidity.

2.Super Long
This Fdrill is utilized when the material thickness or special circumstances require a longer cylindrical geometry.

3.Super Short
This Fdrill is utilized when the material thickness or special tolerances (i.e. within a pipe) require a shorter cylindrical geometry.

4.Special radius for the top of the Fdrill
The top of the cylindrical part can be modified to control the shape of the formed collar or to create a countersunk hole.

5.Special Angle for the Fdrill 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.
