Greenlee 50203509 Spade Bit, 5/8" Diameter, 6-1/4" Length, Hex Shank

The Greenlee 50203509 Spade Bit is a 6-1/4" (158.800 mm) overall length wood boring bit engineered with a 5/8" (15.900 mm) bit diameter and a 1/4" (6.400 mm) hexagonal shank for secure, slip-resistant chucking in drills and drivers. Built for electricians and tradespeople who need to bore clean holes for cable and conduit runs through hardwood, softwood, plywood, and drywall, this spade bit delivers the fast material removal and consistent hole diameter that professional installers rely on for rough-in wiring. The hexagonal shank design ensures positive engagement in quick-change chucks, reducing bit slippage during high-torque boring applications on the jobsite. Sourced through Greenlee's established manufacturing standards, this bit is a dependable, repeatable-tolerance addition to any electrician's or contractor's toolkit for framing bay and joist penetrations.

Greenlee 50203509 – Frequently Asked Questions

1) What diameters do the Greenlee hex shank spade bits come in?
Five diameters: 5/8, 3/4, 7/8, 1 and 1-1/8 inch. The part numbers run 50203509 (5/8), 50203525 (3/4), 50203541 (7/8), 50203576 (1 inch) and 50203584 (1-1/8). All share the same 6-1/4 inch overall length and 1/4 inch hex shank, so you can run a set through the same quick-change chuck without swapping adapters.
2) Will a 1/4 inch hex shank spade bit fit my impact driver?
Yes. The shank is a 1/4 inch hexagonal shank, which is the standard quick-change size an impact driver or drill/driver collet accepts directly, no chuck adapter needed. The hex flats also stop the bit spinning in the chuck when the paddle bites and torque spikes.
3) Is a 6-1/4 inch spade bit long enough to drill through a wall stud?
For a single 2x4 or 2x6 stud bored face-on, yes. The 6-1/4 inch overall length includes the shank, so usable cutting reach is shorter than that figure, and it will not carry you through doubled plates, built-up headers or a stud stack. For deep penetrations through multiple framing members you want a longer bit or an extension.
4) What materials can these Greenlee spade bits bore?
Hardwood, softwood, plywood and drywall. That covers the usual rough-in work: pulling cable and conduit through studs and joists, and opening drywall for device boxes. These are wood boring paddle bits, so they are not the tool for steel studs, masonry or metal plate.
5) Which spade bit diameter should I use for romex and conduit runs?
Match the hole to the cable bundle or the conduit OD plus clearance. Of the five sizes offered, 5/8 and 3/4 inch are the common picks for single or paired NM cable runs through studs, while 7/8, 1 and 1-1/8 inch give room for multiple cables or larger raceway. Sizing up slightly makes the pull easier and reduces jacket abrasion on long runs.
6) Spade bit or auger bit for electrical rough-in?
A spade bit like this Greenlee is the faster, cheaper choice for shallow bores in wood framing and drywall, and the flat paddle clears chips quickly on single-member penetrations. An auger pulls itself through deep stacked lumber under less push and tracks straighter, so it is the better call for long joist runs or doubled plates. With 6-1/4 inch of overall length, the spade is aimed at the single-member bore.
7) Are these spade bits sold individually or as a set?
Each diameter is ordered as its own part number, 5/8 through 1-1/8 inch, so you buy the sizes you need rather than a fixed kit. Buyers standardizing a crew's tool bags usually order the full span of five since they all run off the same 1/4 inch hex shank.
