Acker - Finger Type Cutter Head

This drill head or "Cutter Head" is designed for use on Conveyor Flight type augers. The head is constructed of high quality steet and designed for use with hard faced or carbide inset type finger cutters. Carbide insert fingers are commonly used to drill reasonably hard rock and shales. The cutter head is held on the flight auger by means of a drive clip pin and rotated by the standard shank and socket connection. Finger teeth are held in place by a drive wedge or soft wire pins. Select cutter head diameter on basis of hole diameter desired and select flight size or diameter, about 10% less than cutter head diameter...or hole size.
