General Information
Rottler CBN and PCD Inserts are laser marked with our part number on one side. On single sided inserts,
the part number is on the back side of the insert.
Rottler surfacing insert toolholders are designated IC (inscribed circle) which means they can hold square
and round inserts with the same IC, for example, a 3/8” IC round and 3/8” IC square insert will fit into the
standard 3/8” IC Rottler toolholders.
Rottler SF Series machines are supplied standard with Rottler 3/8” IC toolholders fitted to our surfacing
heads. Optional 1/2” tool holders are interchangeable with 3/8” toolholders.
Cutting Speed Calculation
Inserts are designed to cut within a speed range (S.F.P.M.). In order to convert from cutting speed to
RPM, use the following formula:
RPM = S.F.P.M. X 3.82
DIAMETER
S.F.P.M. = Surface Feet per Minute
RPM = Revolutions per Minute
