Greenlee 50317920 – Frequently Asked Questions

1) Will the Greenlee 50317920 Nail Eater Extreme auger bit fit my 1/2 inch drill chuck?
The bit has a 7/16 inch hexagonal shank, so it seats in a 1/2 inch chuck and in impact-style hex holders. Greenlee calls for a minimum 3/8 inch drill on the 5/8 through 1 inch sizes, with a 1/2 inch drill on all big shank bits. At 3/4 inch diameter you can run it from a 3/8 inch drill, but a 1/2 inch drill gives you the torque you want when it hits a nail.
2) Can this Greenlee auger bit go through nails in old framing?
That is what the Nail Eater Extreme is built for. It is heat treated steel, and the cutting geometry is intended to chew through embedded nails in remodel framing instead of stalling or walking off. On a rewire where you cannot see what is inside the stud, that is the difference between finishing the hole and burning a bit.
3) Is a 3/4 inch auger bit the right size for pulling romex through studs?
3/4 inch is the common electrician's hole for running a couple of runs of NM cable through framing, and this Greenlee Nail Eater Extreme bores exactly that at 3/4 inch (19.1 mm). If you are bundling more conductors or pulling flexible conduit, step up to a larger diameter in the same Nail Eater line rather than drilling twice.
4) Will this bit work in a right angle drill or a hex impact driver?
The 7/16 inch hexagonal shank is the standard drive for right-angle stud-and-joist drills and it also drops into a 7/16 inch hex holder. Greenlee specifies a 3/8 inch drill as the minimum for this size range, so a compact right-angle drill is enough, though a 1/2 inch class tool handles the torque spike better when the bit meets a nail.
5) What exact part number do I order for the 3/4 inch Greenlee Nail Eater Extreme Shorty?
Order Greenlee 50317920. It is the 3/4 inch diameter Extreme Shorty with the 7/16 inch hex shank, made in the USA. One part number, no handing or length options to specify.
