Greenlee 66PT-3/4 – Frequently Asked Questions

1) Can this auger bit really drill through a nail without wrecking the cutting edge?
That is what the Nail Eater Extreme is built for. The heat-treated steel body and patented cutting angle let it cut through nails it hits mid-bore and keep going, instead of chipping the spur the way a standard auger does. It matters most in remodel work where you are boring through old plates and studs with no idea what fasteners are buried in them.
2) Do I need to push hard on a self-feeding auger bit?
No. The screw point on the tip threads into the wood and pulls the bit through, so you guide it and let it feed rather than leaning on the drill. Keep the drill square to the face and back out slowly at the end of the hole so the flutes don't bind. Fighting a self-feed bit with pressure is how you stall the drill or snap a wrist on a right angle tool.
3) Is the Greenlee 66PT-3/4 worth it over a plain auger bit for a crew doing daily rough-in?
The tradeoff is bit life against nail damage. Greenlee rates the improved cutting edge at 30 percent longer life than a standard bit, and because it survives hitting fasteners, one bit gets through remodel plates that would retire an ordinary auger. For new construction in clean lumber, a standard auger does the same hole; the Extreme earns its keep on renovation and service work.
4) What part number do I order for the 3/4 inch by 18 inch Nail Eater Extreme?
Order Greenlee 66PT-3/4. That number covers the 3/4 inch diameter, 18 inch overall length bit with the 7/16 inch hex shank. The Nail Eater family runs across several diameters, so the fraction in the part number is the bore size, and the bit ships as a single piece with nothing else required to run it.
5) How heavy is this bit for overhead boring above a ceiling?
The bit weighs 1.2 lb (545 g) on its own. Add that to a right angle drill and it is manageable overhead, but at 18 inches long it carries leverage, so keep both hands on the tool and expect kickback if the screw point grabs in a knot or a nail.
