Greenlee 50309315 Nail Eater Extreme Hex Shank Wood Boring Bit

The Greenlee 50309315 Nail Eater Extreme Wood Boring Bit is a heavy-duty auger-style bit built from Heat Treated Steel for electricians and contractors who bore through nail-embedded framing, studs, and joists during rough-in wiring and conduit installation. This bit features a 1.000 IN (25.400 MM) bit diameter, an 18.000 IN (457.200 MM) overall length, and a 15.000 IN (381.000 MM) twist length, giving installers the reach needed to punch through multiple stud bays in a single pass. A 7/16 IN (11.100 MM) hexagonal shank ensures a secure, slip-resistant fit in impact drivers and drill chucks, letting the bit transfer maximum torque without cam-out during demanding jobsite use. Manufactured in the US, this bit is purpose-built for professionals who need dependable performance on real construction sites where hidden fasteners are a constant risk.

Key Features

  • Bit Diameter: 1.000 IN (25.400 MM) for clean, consistent boring through framing lumber.

  • Overall Length: 18.000 IN (457.200 MM) provides extended reach for boring through thick or multiple framing members.
  • Twist Length: 15.000 IN (381.000 MM) of flute length clears chips efficiently during deep bores.
  • Shank Type: Hexagonal 7/16 IN (11.100 MM) shank locks securely into drill and impact driver chucks to prevent slippage.
  • Compact Footprint: Product dimensions of 18.9 IN length, 1.7 IN width, and 1.6 IN height keep the bit manageable for tight jobsite storage.
  • Field-Ready Weight: Packaged weight of 1.73 LB keeps the bit balanced and easy to control during extended boring tasks.

Greenlee 50309315 – Frequently Asked Questions

1) Will the 7/16 inch hex shank on this Greenlee auger fit my drill?
The 50309315 has a 7/16 inch (11.1 mm) hexagonal shank. That drops straight into the quick-change chuck on a right angle drill or a heavy duty 1/2 inch hole hawg style drill, and it will also clamp in a standard 1/2 inch keyed or keyless chuck. The hex flats keep it from spinning in the jaws when the bit grabs.
2) How deep can the Greenlee Nail Eater Extreme 50309315 bore in one pass?
Overall length is 18 inches with 15 inches of that being flute, so the usable boring depth is the 15 inch twist. That clears a doubled or tripled stud pack, a 2x12 joist face, or a top plate assembly in a single pass without an extension.
3) Can this auger bit go through nails in old framing?
Yes, that is the point of the Nail Eater Extreme design. The bit is heat treated steel, and the cutting head is built to chew through embedded nails and screws rather than chip out on them, which is what kills a standard wood auger during remodel and retrofit boring.
4) Does the Greenlee 50309315 auger come with an extension or adapter?
No. The 50309315 ships as the bare 1 inch auger bit with its 7/16 inch hex shank. If you need to bore deeper than the 15 inch flute, you add a separate hex bit extension, ordered on its own.
5) What is the exact part number and weight for the Greenlee Nail Eater Extreme 1 inch auger?
Order it as Greenlee MPN 50309315. Packaged weight is 1.73 lb and the packed carton runs about 18.9 by 1.7 by 1.6 inches. It is made in the USA.
