ƒ Independent height and diameter setting permits balanced cutting with production of almost perfectly round holes
from the beginning, irrespective of core shifts.

ƒ Two height balanceable cutting edges results in metal removal at rates almost 4 times that of a single cutter.

ƒ Height adjustments are made with a cam that supports the insert holder where needed, at the furthest radial
point.
ƒ Each insert holder can be adjusted individually in diameter with a dial screw for fast, easy set-up operations.

ƒ Balanced or stepped cutting can be done with the same set of insert holders permitting heavy stock removal and
