MegaMax Boring System
Diameter Extenders
5.9-31.7” (150-805)
Diameter Extenders
Double cutter operation capable in roughing and finishing. Two cutters balance
the assembly as well as the cutting pressures for smooth, vibration-free boring up
to 3250 surface feet.
All assembly surfaces utilize ground serrations for maximum rigidity. Large cap
screws hold components together tightly for faultless transmission of torques and
cutting forces.

Mating surfaces are precision
ground in a wedge-lock serrated
pattern. The grooves do not
bottom so that their faces can
lock in full contact for maximum
rigidity and accuracy.
