DIN 509 E – undercut parameters
Diameter I K R W
<= 1.6 0.1 0.5 0.1 15°
> 1.6 – 3 0.1 1 0.2 15°
> 3 – 10 0.2 2 0.2 15°
> 10 – 18 0.2 2 0.6 15°
> 18 – 80 0.3 2.5 0.6 15°
> 80 0.4 4 1 15°
The undercut parameters are
determined from the cylinder
diameter.
Where:
I: Undercut depth
K: Underc. breadth
R: Undercut radius
W: Undercut angle
