Boring a curved hole with the KIK® Forstner is easy. Simply start straight on the work piece
and just after penetration begin to lean the drill over pointing it in the direction you wish to curve.
Continue feeding the drill until it begins to exit the work piece. Use gentle pressure while finishing the exit
hole to reduce tear-out.
The following tables provide precise information for producing curved holes. Both minimum and maximum values are
given assuming the drill bit is secured 1" into the drill chuck. Any combination within these ranges can be used.
Shown in the diagram at right:
"A" is the center of the bit where the hole is started.
"B" refers to the center of the exit hole.
"C" indicates the measurement to the top of the exit hole.
