Greenlee 33L-3/4 – Frequently Asked Questions
1) Will the Greenlee 33L-3/4 spade bit fit my cordless drill chuck?
The 33L-3/4 has a 1/4 inch hexagonal shank, so it drops into any 1/4 inch or larger drill chuck and also seats in a hex quick-change holder. Greenlee calls for a 1/4 inch or larger power drill. The hex flats keep it from spinning in the jaws when the bit bites in deep stock.
2) What is the hole in the end of this Greenlee spade bit for?
That hole in the top center is for wire pulling. After you bore through, you feed a pull wire or fish line through the hole and draw it back with the bit, so the hole you just drilled is already strung. It saves a second trip with a fish tape on electrical rough-in.
3) How many 12-2 or 14-2 cables can I run through a 3/4 inch bored hole?
The bit cuts a 3/4 inch (19.1 mm) hole, which is the common rough-in size electricians use for pulling a small bundle of NM cable through framing. If you need more cable in a single penetration, step up to a larger spade or auger diameter rather than overfilling a 3/4 inch bore.
4) Can this bit drill drywall and plywood as well as framing lumber?
Yes. The 33L-3/4 is rated for hardwood, softwood, plywood, and drywall. It is a wood-boring spade bit, so it is not for masonry, steel studs, or tile.
5) Should I use a long spade bit or an auger bit for drilling through studs?
A long spade bit like the 33L-3/4 is the cheaper, faster-cutting choice for 3/4 inch holes in wood framing, and the wire pulling hole in the tip lets you drag cable back through on the same pass. An auger self-feeds and tracks straighter through thick or nail-laden stock, but pulls harder on the drill. For a run of holes in clean dimensional lumber, the spade bit is the usual pick.
6) Is this spade bit built for daily production use or occasional work?
It is forged and heat treated, which is what Greenlee builds for repeat trade use rather than a stamped homeowner bit. At 0.4 lb (181 g) it is light enough to run overhead in a drill all day. Resharpening the two cutting lips with a file brings it back when it dulls.
7) What model number do I order to standardize this bit across my crews?
The part number is Greenlee 33L-3/4, the 3/4 inch size in the long spade bit line with the wire pulling hole. Order by that number so you get the 16 inch length rather than a standard-length spade of the same diameter.
