Irwin 373001 – Frequently Asked Questions

1) What's the difference between the Irwin 373001 and 373002 hole saw mandrels?
Shank size. The 373001 is the 3/8 inch hex shank version, and the 373002 is the 1/2 inch hex shank version. Both are Irwin hole saw mandrels (arbors) in heat-treated S2 steel, so the choice comes down to what your chuck takes and which shank your existing setup is built around.
2) Will a hole saw mandrel with a hex shank hold in a standard drill chuck?
Yes. The hex shank seats in standard drill and driver chucks and resists slipping under the torque a hole saw generates. A round shank can spin in the jaws once the saw binds in the cut; the hex flats give the chuck something to grip. The 373001 uses a 3/8 inch hex shank.
3) Can I buy an Irwin hole saw mandrel on its own to replace a broken one from my kit?
Yes, these are sold as individual arbors rather than part of a saw set, and replacing the mandrel in an existing hole saw kit is one of their normal uses. Match the shank to your drill (3/8 inch is part 373001, 1/2 inch is part 373002) and confirm your saw falls in the arbor's cup diameter range.
4) Is the S2 steel on these Irwin hole saw arbors actually better than a plain steel mandrel?
S2 is a shock-resisting tool steel, and Irwin heat-treats it on these mandrels. That matters on a hole saw arbor because the pilot bit and the saw take hammering loads every time the cut breaks through or the saw grabs, which is where a soft arbor body twists or the pilot seat wallows out.
5) How are Irwin 373001 hole saw mandrels packaged for a shop or MRO stockroom?
The 373001 ships 5 pieces per box, model code AD, which suits a crib or service van where arbors get lost and broken rather than a one-off purchase. Country of origin is the United States.
6) Does this Irwin arbor come with a pilot drill bit?
Irwin lists these as hole saw mandrels (arbors) only, with no battery or accessory content called out. Plan on sourcing the pilot bit and the hole saw separately when you order the arbor.
