Irwin 373003 – Frequently Asked Questions

1) What size hole saws will the Irwin hex shank hole saw arbor drive?
The Irwin hex shank arbor is built to accept compatible hole saws from 1-1/4 inch up to 6 inch diameter. Below 1-1/4 inch you are into the small-diameter saws that use their own integral or smaller mandrel, so this arbor is not the right driver for those.
2) If the pilot bit snaps, do I have to buy a whole new hole saw arbor?
No. The pilot drill is removable on these Irwin arbors, so a worn or broken pilot comes out and a replacement goes in without scrapping the arbor body. That is the difference between a consumable pilot bit and a consumable tool.
3) Is a pilot drill included with the Irwin hex shank arbor?
Yes, each version ships with a removable pilot drill, so you can mount a hole saw and cut without sourcing a pilot separately.
4) Is this arbor made in the USA?
Yes, country of origin on the Irwin hex shank hole saw arbor is the United States, which matters if you are buying against a domestic-preference or Buy American line item on a government or institutional order.
5) Is this arbor suitable for electricians running conduit and device boxes?
It is catalogued for electrical work and covers the hole saw range electricians use day to day, 1-1/4 inch up through 6 inch, for recessed cans, box knockouts and larger penetrations. Plumbing and general construction hole saw work uses the same arbor.
6) Does this hole saw arbor need batteries or any power source of its own?
No. It is a passive drive accessory, no battery and no power source, listed as non-energy using. All the power comes from the drill it is chucked into.
