Hougen 12223 23/32" X 2" Rotabroach "12,000-Series" Tap Drill, 2" DOC,1/2-14 NPT

Hardened M2 high speed steel material; Precision ground & fully fluted provides better chip evacuation, requires less horsepower & offers better performance in deeper holes; 3/4" double flatted shank is very rigid & offers up to 2 times the tool life as compared to quick change tool mounting on competitive products; Only a thin area of material touches the outside of the hole which provides for less friction and a better hole finish; Patented hougen-edge geometry provides faster, smoother cuts, with less chatter; Tapered inner diameter provides a relief area between the slug & cutter to reduce horsepower & improve slug ejection; Up to 10 cutting edges distribute the cutting load evenly to maximize feed rates; The slug offers a higher scrap value than loose chips
