Norseman-Viking Hole Hog Core Drills Set
With Companion Pilot Drills - Black & Gold Oxide Coated - USA Made
Norseman's Hole Hog Core Drills Set is built for superior drilling performance and comes with companion pilot drills for each corresponding core drill. Hole Hog core drills are used primarily to enlarge existing holes, but can also be used for cutting large diameter holes in thin materials. Hole Hogs can replace tapered reamers in many applications where a significant amount of material must be removed or a particular size hole is required. The 4 flute design of the Hole Hog eliminates the catching and hogging-in experienced with standard drills when breaking through thinner materials.
The round shank has flats ground onto three sides to reduce slippages of the bits when used in drill chucks. When run in a counterclockwise direction (right hand), spiral fluted tools evacuate chips up and out of the cut to reduce clogging.
Recommended for use with work hardening grades of stainless steel, alloy steel, and other hard metal drilling applications. The smallest hole which may be enlarged by a Hole Hog is represented by the accompanying pilot drill (shown to the left of the core drill it's meant for in the case). Pilot drills have a 135-Degree Split Point. Made in the USA.
