Hougen® Rotabroach® 12146 12000 Annular Cutter, 1-7/16 in Dia Cutter, 1 in D Cutting, M2 HSS, Uncoated, 2-Flat Shank

Hougen "12000 Series" cutters were the original annular cutters invented over 35 years ago. With the most features of any annular cutter, "12000 Series" cutters provide the best performance in the largest variety of materials. Compared to traditional tooling (twist drills, etc.) "12000 Series" cutters can multiply your cutting speed by up to 3 times. And you get longer tool life, a more accurate hole, a better finish, with no burrs. Hougen cutters maximize feed rates because up to 10 cutting edges distribute the cutting load evenly. "12000 Series" cutters convert a smaller area to chips, requiring less horsepower and thrust.

• Ground and fully fluted - Provides better chip evacuation, requires less hp and offers better performance in deeper holes
• Two flats for cutter mounting - This system is very rigid and offers up to 2x the tool life as compared to quick change tool mounting on competitive products
• OD Margin - Only a thin area of material touches the outside of the hole which provides for less friction and a better hole finish
• ID Taper - Relief area between slug and cutter
• The Hougen-Edge® feature is a patented tooth geometry that provides long tool life, less chatter and extended resharpenability
• The slug also offers a higher scrap value than loose chips
• For use with 10527 pilot
• For use with Hougen® portable magnetic drills and many competitive models on materials up to 6 in thick
• They are made from hardened M2 high speed steel and are precision-ground for excellent performance throughout the cut and long tool life
