Norseman SP-8HH Hole Hog™ Super Premium 4-Flute Core 8 Piece Drill Bit Set 38880

Hole Hog™ Super Premium 4-Flute Core Drill Bit Set

Type 134-AG

This tool is designed exclusively for enlarging existing holes. The 4-flute design eliminates the catching and hogging-in experienced with standard S & D drills when breaking through thinner materials such as truck frames. These core drills may replace tapered reamers in many applications. Set includes a selection of core drills and companion (minimum starting hole size) pilot drills in a black steel index. Core drills have a 1/2" shank with 3-flats on shank.

Set includes 134-AG core drill sizes 3/8", 1/2", 5/8" and 3/4"; 175-AG drill sizes 1/4", 5/16", 25/64" and 15/32".
