Greenlee 34AR-6 – Frequently Asked Questions
1) What sizes come in the Greenlee 34AR-6 spade bit set?
Six bits: 3/8, 1/2, 5/8, 3/4, 7/8 and 1 inch. That range covers the common electrical rough-in holes, from small single-cable runs at 3/8 inch up to 1 inch for conduit or bundled runs through studs and joists. All six are 6-1/4 inches overall length, so they bore through a single 2x4 or 2x6 framing member without needing an extension.
2) What is the hole in the tip of these Greenlee spade bits for?
Wire pulling. Each bit has a hole in the top center, so after you bore through a stud you can hook fish tape or a pull wire to the bit and draw it back through the hole in the same motion. It saves a second trip with a fish rod on electrical rough-in through framing.
3) Will these spade bits fit my cordless drill?
The 34AR-6 bits are made for use in a 1/4 inch or larger power drill chuck. Any standard 3/8 inch or 1/2 inch keyless chuck on a cordless drill/driver takes them. Note these are round-shank spade bits, not 1/4 inch hex quick-change, so an impact driver with a hex-only collet will not hold them.
4) What materials can the Greenlee 34AR-6 set drill?
Hardwood, softwood, plywood and drywall. These are wood-boring spade bits, so they are not for metal studs, masonry, or tile. If you are drilling steel studs for a wire run, you need a step bit or a hole saw rated for metal instead.
5) What does self-feeding mean on a spade bit, and is it better than a standard spade bit?
The tip pulls itself into the wood as it turns, so you supply less push and the drill does the work. Greenlee lists less effort and reduced vibration as the result, which matters most when you are boring a long line of studs overhead. The tradeoff versus a plain spade bit is that a self-feeding tip grabs, so hold the drill firmly and use a drill with a clutch or side handle on the 7/8 and 1 inch sizes.
6) What is the Greenlee part number for the 6-piece self-feeding spade bit set?
Greenlee 34AR-6. That is the full six-bit kit covering 3/8 through 1 inch, sold as one set rather than individual bits.
7) Will these bits hold up to daily use on a job site?
The bits are forged and heat treated, which is what gives a spade bit edge retention through repeated use rather than a stamped blank that rolls over after a few dozen holes. For an electrical crew drilling framing day in and day out, that construction is the difference worth paying for. They will still dull if you hit nails, so keep a spare 3/4 inch on hand for remodel work.
