Bottom Line - Saves You Time and Money
Hougen Cutters drill a burr-free hole by cutting around the hole and
ejecting the center as a usable slug. Hougen Cutters require far less
horsepower than twist drills of comparable size when run at the same
feed rate. As a result, cutters can be run at higher feeds with higher
metal removal rates while horsepower requirements are not increased.
The geometry of Hougen Cutters is such that far less material is
converted into chips than when using twist drills. Far less thrust is
required by Hougen Cutters because they do not have a dead-center
area like the chisel edge region of twist drills. Thrust required is 50%
of smaller diameter twist drills and 10% or less for larger diameters.
More cutting edges at work during each revolution smooths out
finishes and reduces chip loads per tooth as compared to twist drills.
From three to 12 teeth per cutter, depending upon diameter, helps
tools last longer, even at higher feed rates.
Experience the Hougen Edge®
Our exclusive and patented end-tooth geometry - the Hougen-Edge,
is one of the reasons Hougen Cutters require less thrust and improve
finish and tool life. The alternating tooth angles equalize forces to
keep the cutter path straight, even thru the deepest holes.
