3-48 INTERNAL THREAD RELIEF MILLS by AB Tools

CHAMFER-HOGS SINGLE-FLUTE
The Single Flute Chamfer Hog by AB Tools, Inc. was developed in 1982 for spot drilling and chamfer milling small slots in non-ferrous part materials. If used prior to drilling non-ferrous materials it performs well. If used as a countersink after the hole is drilled it is chatter prone.
