Features·Annular cutters only 1/4 inch in diameter for hand-held drills. ·Patented Hougen Edge Geometry provides faster and smoother cuts with less chatter. ·Inner diameter taper reduces horsepower and improves slug ejection. ·Outer diameter margin provides close tolerance for less friction and better hole finish. ·Ground & fully fluted profile provides for better chip evacuation and better performance in deeper holes. ·Made of hardened high-speed steel with a precision ground geometry.Applications·Use with hand-held drills or drill presses.·For sheet metal or plate up to 1/2 inch thick.·Workpiece materials range from Steel, Non-Ferrous, Cast Iron to Plastics.·Perfect for the following areas: electrical, pipe and tubing, conduit work, sheet metal fabrications, and HVAC/PHCC.Benefits·Hougen cutters maximize feed rates as multiple cutting edges distribute the cutting load evenly. ·As a result, Hougen Cutters require less horsepower and thrust. ·The consequence of which is cleaner cut, burr-free holes.·Most Hougen cutters can be resharpened up to 15 times, depending on the wear.·Longer wear than hole saws.
