Greenlee 50309234 Nail Eater Extreme 3/4 IN Auger Bit, Heat Treated Steel

The Greenlee 50309234 Nail Eater Extreme is a heavy-duty auger bit engineered for electricians and installers who need to bore through wood framing without slowing down for embedded nails. Built from heat treated steel with a 3/4 IN (19.100 MM) bit diameter, this bit delivers the durability and cutting performance demanded on commercial and residential job sites. Its 18.000 IN (457.200 MM) overall length and 15.000 IN (381.000 MM) twist length let installers reach deep into stud bays and joists for conduit, cable, and wiring runs, while the hexagonal 7/16 IN (11.100 MM) shank ensures a secure, slip-resistant grip in standard drill chucks. Whether you're running new electrical rough-in or tackling a renovation where hidden fasteners are a real risk, this bit is designed to keep cutting instead of chipping.

Key Features

  • Bit Diameter: 3/4 IN (19.100 MM) sized for standard electrical and low-voltage boring applications.
  • Durable Construction: Heat Treated Steel body resists wear and holds an edge even when striking embedded nails and fasteners hidden in framing.
  • Overall Length: 18.000 IN (457.200 MM) provides extended reach through deep framing members and multiple stud bays.
  • Twist Length: 15.000 IN (381.000 MM) flute design clears wood chips efficiently for faster, cleaner holes with less binding.
  • Shank Type: Hexagonal 7/16 IN (11.100 MM) shank locks securely into drill chucks to minimize slippage under heavy load.
  • Compact Footprint: Overall product dimensions of 18.7 IN length, 1.15 IN width, and 1.1 IN height keep the bit manageable in tight work areas.
  • Lightweight Design: Packaged weight of 1.02 lbs keeps the bit easy to carry and maneuver on ladders and in crawl spaces.

Greenlee 50309234 – Frequently Asked Questions

1) How thick a wall can I bore through with the Greenlee 50309234 Nail Eater Extreme?
Overall length is 18 inches with 15 inches of that being flute (twist) length, so the usable boring depth is about 15 inches before the shank bottoms out. That handles a doubled 2x top plate, stacked studs, or angled bores through a 2x6 wall in one pass. For deeper runs you would need an extension or a longer bit.
2) Can this auger bit go through nails without wrecking the cutting edge?
That is what the Nail Eater Extreme is built for. The bit is heat treated steel, so it survives incidental strikes on nails and light metal embedded in framing, which is the usual killer of standard wood augers on remodel work. It is still a wood boring bit, not a metal drilling bit, so treat nail hits as incidental rather than routine.
3) Will an 18 inch auger bit fit between studs on 16 inch centers?
Not straight on. At 18 inches overall it will not swing perpendicular in a 14-1/2 inch stud bay, so plan on a right angle drill or bore at an angle. The 15 inch flute gives you room to work once the bit is started.
4) Is the Greenlee 50309234 a single bit or a kit with multiple sizes?
It is one bit, MPN 50309234, in the 3/4 inch diameter only. If you are stocking a van or a shop for rough-in, you will want the other diameters ordered separately alongside it.
5) Is this Greenlee auger bit made in the USA?
Yes, country of origin on the 50309234 Nail Eater Extreme is the United States. That matters on public and institutional jobs carrying domestic sourcing requirements.
