Lenox 1972920 – Frequently Asked Questions

1) Will the Lenox MetalMax cut-off wheel fit my 4-1/2 inch angle grinder?
Yes, if you order the 4-1/2 inch wheel with the 7/8 inch arbor, MPN 1972921. That 7/8 inch bore is the standard spindle arbor on 4-1/2 inch angle grinders, so it drops straight on. The MetalMax line also comes in a 4 inch size with a 5/8 inch arbor (MPN 1972920), which will not seat correctly on a 7/8 inch grinder spindle without the right bushing, so match the arbor to your tool, not just the diameter.
2) What is the difference between the two Lenox MetalMax wheel sizes?
Two combinations are offered: 4 inch diameter with a 5/8 inch arbor (1972920) and 4-1/2 inch diameter with a 7/8 inch arbor (1972921). Diameter sets your depth of cut and has to match what your guard allows; the arbor has to match your spindle. Smaller grinders and some cordless tools take the 4 inch / 5/8 inch wheel, while the common corded 4-1/2 inch grinder takes the 7/8 inch bore.
3) Can a diamond cut-off wheel cut steel, or is it only for masonry?
The MetalMax wheel is a metal-cutting wheel. Its diamond cutting edge is built for ferrous material, sheet metal and rod stock, so it handles steel stud, conduit, threaded rod, angle iron and light plate. It is not a masonry or tile wheel, and nothing in the Lenox spec supports using it that way.
4) Why use a diamond edge wheel instead of a cheap abrasive cut-off disc?
An abrasive disc wears down as it cuts, so the diameter shrinks, depth of cut drops, and you change discs through the day. The MetalMax diamond edge holds its cutting surface through extended use, which means fewer wheel changes and less downtime mid-task. If you only make a handful of cuts a year, a bonded abrasive disc is the cheaper call; for electricians cutting strut and conduit all day or fabricators running repeated cuts, the diamond edge is what reduces stoppages.
5) Is this the right wheel for cutting threaded rod and strut on a commercial electrical job?
Yes. Rod stock and sheet metal are named applications for the MetalMax diamond edge wheel, which is the bulk of what an electrical crew cuts: hanger rod, strut, EMT, box knockouts. The 4-1/2 inch size with the 7/8 inch arbor is the one that fits the grinders already on most electrical trucks.
6) I need to standardize one cut-off wheel across a maintenance shop with mixed grinders. Which Lenox MetalMax do I stock?
Stock by arbor, not by brand of grinder. If every tool in the shop is a 4-1/2 inch grinder, carry 1972921 (4-1/2 inch x 7/8 inch) as the single line item. If you also run 4 inch tools with 5/8 inch spindles, you need 1972920 as a second line. Those are the only two configurations in the MetalMax diamond edge cut-off wheel range, so two part numbers cover the whole shop.
7) Does the Lenox MetalMax wheel come with an arbor adapter or mounting flanges?
No. It is the wheel only, with the arbor bore sized into the wheel itself (5/8 inch on the 4 inch version, 7/8 inch on the 4-1/2 inch). You mount it on your grinder's existing inner and outer flanges and spindle nut, so the tool has to already be complete.
