Greenlee 50317962 Nail Eater Extreme Hex Shank Drill Bit

The Greenlee 50317962 Nail Eater Extreme Hex Shank Drill Bit is an Extreme Shorty style bit built from Heat Treated Steel for maximum durability when boring through wood studs, joists, and other framing members that may contain embedded nails or fasteners. With a 7/8 IN (22.200 MM) bit diameter and a compact 7-5/8 IN (193.700 MM) overall length, this bit is engineered to power through tough, nail-embedded lumber where standard bits would chip, dull, or fail. The hexagonal 7/16 IN (11.100 MM) shank delivers a secure, slip-resistant grip in impact drivers and drills, making it a dependable choice for electricians, low-voltage installers, and contractors running cable and conduit through framing on the jobsite. Compact overall dimensions of 8.250 IN length x 1.100 IN width x 1.150 IN height keep the bit maneuverable in tight framing bays while its 5.000 IN (127.000 MM) twist length clears chips and debris efficiently during extended drilling runs.

Greenlee 50317962 – Frequently Asked Questions

1) Will the Greenlee 50317962 Nail Eater Extreme bit fit in an impact driver?
Yes. The 50317962 has a hexagonal 7/16 inch shank, so it seats in impact drivers and drill chucks that accept a 7/16 inch hex. The hex flats keep it from spinning in the chuck when the bit bites hard in a nail-embedded stud.
2) How thick a wall or joist can a 7-5/8 inch Nail Eater Extreme Shorty actually drill through?
Usable boring depth is governed by the 5 inch twist length, not the 7-5/8 inch overall length, because the back portion is shank. That handles a single 2x4 or 2x6 stud or plate easily, but it will not pass through doubled top plates plus a header in one shot. For deeper runs you want a full-length Nail Eater or a bit extension; the Shorty exists for control and access in tight framing bays.
3) Will this bit survive hitting a nail or a joist hanger screw?
That is what it is built for. The Nail Eater Extreme body is heat treated steel so the cutting edges hold up on contact with embedded nails and fasteners that chip or dull ordinary wood auger bits. It is still a wood bit, not a metal-cutting bit, so treat it as nail-tolerant rather than a substitute for drilling steel.
4) Is a 7/8 inch hole big enough for the cable I'm pulling through studs?
The 50317962 bores a 7/8 inch (22.2 mm) hole, which is the common rough-in size electricians use for pulling multiple NM cables or small conduit through wood framing. If you need a hole sized to a specific trade conduit size, match the bit diameter to the outside diameter of what you are running, not the trade size.
5) Should I use a short Nail Eater or a long one for stud and joist rough-in?
Pick by access. A Shorty like the 50317962, at 7-5/8 inches overall, gives you control drilling between studs 16 inches on center where a long bit and drill body will not line up. Long versions are for boring multiple framing members in one pass or reaching into a bay you cannot get square to. Many crews carry both and use the Shorty for the majority of single-member holes.
6) What is the exact Greenlee part number to reorder this 7/8 inch Nail Eater Extreme bit?
Order Greenlee part number 50317962. That number covers the 7/8 inch Extreme Shorty with the 7/16 inch hex shank, and it is the single configuration, so there are no diameter or length suffixes to specify.
7) Is the Greenlee 50317962 made in the USA?
Yes, country of origin on the 50317962 Nail Eater Extreme bit is the US. That matters if you are buying against a domestic-preference purchasing policy on a public or institutional job.
