Irwin IRW87950 – Frequently Asked Questions

1) Can an electrician use the Irwin 87950 set for running romex through studs?
Yes, that's the main reason this three-size mix exists. The 3/4 and 1 inch bits bore the clearance holes through studs and top plates for cable runs, and the 1/4 inch handles pilot work. Irwin catalogues the Speedbor Blue Groove line on the electrical side for exactly that kind of rough, fast boring in wood framing.
2) Will Speedbor Blue Groove spade bits work in a cordless drill or do I need an impact driver?
The Speedbor Blue Groove spade bits are made for common corded and cordless drills, so a standard keyless chuck takes them. Nothing in the spec calls out a hex impact-rated shank, so treat these as drill bits rather than impact-driver bits.
3) Are spade bits or hole saws the right choice for boring holes in wood framing?
For wood only, spade bits like these are faster and cheaper, and they clear chips well in soft framing lumber up to about an inch of diameter. Step up to a hole saw when you need diameters larger than the 1 inch top size here, a cleaner edge on finished plywood, or you may hit nails or metal. For long, deep runs through multiple studs, an auger bit pulls itself through better than a spade.
4) Is the Irwin 87950 suitable for drilling metal or masonry?
No. These are woodboring bits, intended for wood and wood products such as framing, cabinetry and furniture stock. Metal calls for twist drills and masonry calls for carbide-tipped hammer bits.
5) Will a 1 inch spade bit bore all the way through a 2x4 stud?
Yes. A 2x4 is 1-1/2 inches thick on the drilled face, so the 1 inch bit in this set bores clean through in a single pass with no extension needed. For deeper work, such as stacked plates, a bit extension is sold separately.
6) What part number do I order for the Irwin 3-piece Speedbor Blue Groove spade bit set?
Irwin manufacturer part number 87950. It ships as a set, not as loose bits, and the bits carry the blue Speedbor Blue Groove finish. Country of origin is China.
