Greenlee 50203649 – Frequently Asked Questions

1) What bit sizes come in the Greenlee 50203649 spade bit kit?
Six bits, 3/8, 1/2, 5/8, 3/4, 7/8 and 1 inch, catalogued individually as 33A-3/8, 33A-1/2, 33A-5/8, 33A-3/4, 33A-7/8 and 33A-1. That spread covers the usual holes an electrician bores for NM cable runs and small conduit pass-throughs in wood framing, so you are not stopping to buy a one-off size mid-rough-in.
2) Are spade bits the right choice for boring studs for cable, or should I use a self-feed or auger bit?
Spade bits like the 33A sizes in this Greenlee kit are the quick, low-cost choice for boring softwood studs and plates for cable, and at 3/8 through 1 inch they handle most NM and low-voltage runs. They cut fast but wander more and leave a rougher hole. For deep boring through multiple members, nail-embedded lumber, or repeated large-diameter holes, an auger or self-feed bit tracks straighter and clears chips better. For 2x framing rough-in, spade bits are what most electricians carry.
3) Can I order the individual 33A spade bits separately instead of the whole Greenlee kit?
The 50203649 ships as one complete six-bit assortment, not as loose pieces. The bits inside carry their own Greenlee designations (33A-3/8 through 33A-1), so if you only need to replace one size you would order that 33A part rather than the kit.
4) Is a 3/8 to 1 inch spade bit kit enough for a residential electrical rough-in, or will I need bigger holes?
For standard branch-circuit work this Greenlee set covers it: 3/8 and 1/2 inch for single cable runs and low-voltage, 5/8 through 1 inch for stacked NM runs, flex, and small conduit pass-throughs through wood framing. If your job includes larger trade-size conduit or boring for multiple stacked raceways you will need bits or self-feed cutters above 1 inch, which this kit does not include.
5) Will the Greenlee 50203649 spade bit kit fit in a tool bag pouch or van drawer?
The kit measures 8.200 by 5.700 by 0.450 inches and 21.033 cubic inches of volume, so it is essentially a flat sleeve. It drops into a bag pocket or a shallow service-van drawer without taking a full tray.
6) Will these Greenlee spade bits work in a cordless drill or do I need an impact driver?
Spade bits are shanked for standard chucks, so a 1/2 inch chuck cordless drill or corded drill runs the 3/8 through 1 inch sizes in this kit. The larger 7/8 and 1 inch bits pull real torque in framing lumber, so a drill with a side handle or a low-speed setting is worth having rather than a compact driver.
7) What is the Greenlee part number and UPC for this spade bit kit?
Greenlee calls it 50203649, which is both the model and the manufacturer part number, with UPC 783310203643. Country of origin is China.
