Toolholders
Top Notch™ threading toolholders are a comprehensive solution for the demands of different machining tasks including facing, grooving, profiling, turning, and threading. They are particularly ideal for coarse pitch and multi-tooth threading applications. The design and construction of these toolholders have a ridged clamping design that assures the best tool life, surface finish, and workpiece quality.
