Greenlee 50309196 Nail Eater Extreme Wood Boring Bit, 5/8 IN, Hexagonal Shank

The Greenlee 50309196 Nail Eater Extreme is a heavy-duty wood boring bit engineered for electricians and contractors who need to drill through framing members that may contain embedded nails or fasteners. Built from heat treated steel, this bit features a 5/8 IN (15.900 MM) bit diameter, an 18.000 IN (457.200 MM) overall length, and a 15.000 IN (381.000 MM) twist length that allows for deep boring through studs, joists, and other structural wood members during electrical rough-in work. The 7/16 IN (11.100 MM) hexagonal shank is designed for a secure, slip-resistant grip in compatible drill chucks and impact-rated drivers, helping transfer torque efficiently even under heavy load. As part of the Greenlee Nail Eater® family, this bit is purpose-built to keep cutting through obstructions that would stop a standard auger bit, reducing downtime on the jobsite. Manufactured in the US, it is designed for professional electrical rough-in crews who need a bit that can survive contact with hidden metal fasteners without dulling or snapping.

Greenlee 50309196 – Frequently Asked Questions

1) How thick a wall can I bore through with an 18 inch Nail Eater auger bit?
The 50309196 is 18 inches overall with 15 inches of twist, so the usable boring depth is the twist length, 15 inches. That clears a standard 2x4 or 2x6 stud bay easily and lets you reach through doubled plates or stacked studs. For deeper runs you would need an extension or a longer bit.
2) What size hole does the Greenlee 50309196 drill, and will that pass my cable?
It cuts a 5/8 inch hole (15.9 mm). That is the common electrical rough-in size for pulling NM cable through studs and plates. If you are bundling multiple runs or pulling larger feeders, step up to a bigger diameter bit.
3) Can a Nail Eater Extreme bit go through nails and screws in old framing?
That is what the Nail Eater line is built for. The 50309196 is heat treated steel, so the cutting head survives contact with embedded nails in remodel framing rather than chipping out the way a standard wood auger does. It is the right choice for retrofit and rewire work in existing walls.
4) Will an 18 inch auger bit fit between studs on 16 inch centers?
Not for a straight-on bore in a 16 inch bay. The 50309196 measures 18.65 inches overall in its packaged length with an 18 inch bit length, so you need clearance for the bit plus the tool behind it. In tight bays, drill at an angle from an open end or use a shorter auger and a bit extension.
5) What is the exact part number and country of origin for the Nail Eater Extreme 5/8 inch auger bit?
Greenlee part number 50309196, made in the US. Specify that number when you are matching what is already in the crew's bit roll, since the Nail Eater Extreme range runs across several diameters and lengths.
