Irwin 1890707 – Frequently Asked Questions

1) What sizes does the Irwin 18907 installer bit come in, and what are the part numbers?
Three orderable sizes in the 18907 installer bit family: 1/4 in. dia. x 18 in. (MPN 1890707), 3/8 in. dia. x 18 in. (MPN 1890709), and 1/2 in. dia. x 18 in. (MPN 1890711). Pick the diameter off the cable bundle you are pulling, not the drill.
2) Can I use the Irwin 18907 installer bit to drill through steel studs or masonry?
No. The 18907 installer bit is a high carbon steel wood bit with an 82 degree point ground for wood framing. Run it through studs, joists, top plates and floor plates. For steel studs or masonry you need a different bit entirely, as carbon steel will dull or burn immediately in those materials.
3) How does the hole in the flute work for pulling wire through a wall?
After you bore through the framing, you thread the wire or fish line through the hole in the flute and reverse the bit back out, dragging the wire with it. The 3-flatted shank also carries a hole, so you can pull from whichever end you can reach. It saves going back with a fish tape on blind cavity runs.
4) Will the 18907 bit slip in a standard drill chuck?
The shank is straight with three flats ground into it, which gives a three-jaw keyless or keyed chuck something to bite on so the bit does not spin under load. It is not a hex or SDS shank, so it goes in any normal drill or right-angle drill chuck.
5) Is the Irwin 18907 sold individually or in a pack?
These ship 10 each per pack, which suits a shop or service van stocking consumables rather than a one-off purchase. Installer bits in wood get retired regularly once the point dulls, so buying by the pack keeps a crew running.
6) Is an 18 inch installer bit long enough to get through a wall and the top plate?
At 18 inches of overall bit length, you have reach for typical stud bays, single and doubled top plates, and floor plates on standard framing. For deeper runs, drilling down through multiple stacked plates or thick built-up headers, you may need a bit extension or a longer flex bit instead.
7) Which diameter 18907 bit should an electrician use for low-voltage and data cable runs?
For single low-voltage or data drops the 1/4 inch (1890707) usually clears the cable. Bundled Cat6 runs or NM cable generally want the 3/8 inch (1890709), and the 1/2 inch (1890711) gives room for multiple conductors through one bore. All three are 18 inches long, so reach does not change with the size you pick.
8) Does this Irwin installer bit need a battery or any power source of its own?
No. It is a non-energy-using accessory with no battery and no lithium content, so it carries no shipping restrictions on that account. All the power comes from whatever drill you chuck it into.
9) Where is the Irwin 18907 installer bit made?
Country of origin is Brazil. That matters on public and institutional jobs where procurement has to record origin on submittals.
