Hougen 3 12000 Annular Cutter - 1-1/8 in - 3 in
Hougen portable magnetic drills and many competitive models on materials up to 275 BHN (28.5 HRC). They are made of hardened M2 high speed steel and are precision ground for excellent performance throughout the cut and long tool life. They require less horsepower and thrust to cut, and last much longer than traditional holemaking methods. "12,000-Series" cutters have a 3/4 in diameter double-flatted shank. Modified end tooth geometry is also available for drilling in stacked plate applications. For extended tool life and lower cost per hole "12,000-Series" cutters are resharpenable.
Features
Hardened M2 high speed steel materialPrecision ground and fully fluted provides better chip evacuation, requires less horsepower and offers better performance in deeper holes3/4 in double flatted shank is very rigid and offers up to 2 times the tool life as compared to quick change tool mounting on competitive productsOnly a thin area of material touches the outside of the hole which provides for less friction and a better hole finishPatented hougen-edge geometry provides faster, smoother cuts, with less chatterTapered inner diameter provides a relief area between the slug and cutter to reduce horsepower and improve slug ejectionUp to 10 cutting edges distribute the cutting load evenly to maximize feed ratesThe slug offers a higher scrap value than loose chipsMakes large diameter holes efficiently without the mess of chipsHole produces a slug of material that could be used for another job
