Greenlee 645-022 – Frequently Asked Questions

1) What size hole cutters does the Greenlee 645-022 arbor accept?
The 645-022 large quick-change arbor takes cutter heads from 2-3/8 inch through 3.000 inch. One arbor covers that whole range, so you are not buying a separate arbor for each cutter size. If your cutters are smaller than 2-3/8 inch, this is the wrong arbor for them.
2) Will the Greenlee 645-022 arbor chuck into my 1/2 inch drill?
Yes. The shank is 1/2 inch diameter, so it seats in a 1/2 inch chuck on a standard corded or cordless drill. A 3/8 inch chuck will not take it.
3) Is the Greenlee 645-022 an arbor only, or does it include a cutter?
Arbor only. The 645-022 is the drive arbor with the 1/2 inch shank that carries the cutter head; you order the cutter heads separately in the sizes you need between 2-3/8 and 3.000 inch.
4) Will a Milwaukee BIG HAWG arbor work with Greenlee carbide cutter heads?
Do not plan on it. The Milwaukee 49-56-9305 is a BIG HAWG series arbor, built around that cutter system, while the Greenlee 645-022 is a quick-change arbor with a carbide cutter shank sized for cutter heads in the 2-3/8 inch to 3.000 inch range. Quick-change arbors use a brand-specific push-and-turn interface, so pair each arbor with cutters from its own line rather than mixing them.
5) What is the closest alternative to the Greenlee 645-022 quick-change arbor from another brand?
The Milwaukee 49-56-9305 BIG HAWG carbide-tooth arbor is the comparable option. Both are quick-change arbors intended to drive carbide hole cutters, so one arbor serves a range of cutter head sizes. The Greenlee 645-022 has a 1/2 inch shank diameter and accepts cutter heads from 2-3/8 inch through 3.000 inch, while the Milwaukee unit is part of the BIG HAWG system and is matched to BIG HAWG cutters. Choose based on which cutter family you already stock, since arbors and cutter heads are keyed to their own systems.
6) How do you change cutter heads on the Greenlee 645-022 quick-change arbor?
It is a push-and-turn mechanism. You push the cutter head onto the arbor and twist to lock, no wrench or separate set screw step, which is the point of the quick-change configuration when you are stepping through several hole sizes in one enclosure.
7) Is the Greenlee 645-022 arbor the right choice for cutting holes in electrical panels and enclosures?
That is what it is built for. Greenlee lists it for electrical panel and enclosure hole cutting, conduit and box knockout prep, and commercial or industrial electrical installs. It is a carbide cutter shank arbor, so it is matched to carbide-tooth cutter heads rather than wood-boring bits.
8) If I only need one or two hole sizes, do I still need a quick-change arbor like the Greenlee 645-022?
Not necessarily. The value of the Greenlee 645-022 is that its push-and-turn design lets one 1/2 inch shank arbor carry cutter heads from 2-3/8 inch to 3.000 inch, so it pays off when you are moving between several sizes on panels and enclosures. For a single repeated hole size, a fixed-pilot hole saw or a one-piece cutter is simpler. The Milwaukee 49-56-9305 BIG HAWG arbor serves the same multi-size purpose within the BIG HAWG cutter line.
9) What is the Greenlee part number to order for the large quick-change arbor?
Order Greenlee 645-022. That is the manufacturer part number for the large quick-change arbor with the carbide cutter shank. It is made in China.
