HERCULES 4-1/2 in. Type 27/42 Metal Cut-Off Wheels, 10-Pack, $5.99 at Harbor Freight

This is a 10-pack of HERCULES 4-1/2 in. metal cut-off wheels, sized 1/16 in. thick with a 7/8 in. arbor, made for standard angle grinders. Harbor Freight's regular price on this item is $12.99, and it's currently showing a member-only deal price of $5.99, which requires being logged into a free Harbor Freight account/Inside Track Club to unlock. The page lists the deal as expiring 8/27, so it's not a permanent price.

At $5.99 for ten wheels, this works out to about 60 cents per disc, which is solid pricing for cut-off wheels from a brand with a strong review record (4.6 stars across 362 reviews). It's a reasonable pickup for anyone doing metalworking, fabrication, or general shop cutting who goes through wheels regularly. Just make sure you're logged into your Harbor Freight account before checkout, since the discounted price won't apply otherwise.

Note that Harbor Freight also sells a cheaper BAUER-branded version of the same size and type for $8.99 without a membership requirement, so it's worth comparing if you don't want to bother with an account. The page also throws in a comparison to a DIABLO wheel at $27.97, but that's a different brand's list price, not a discount off this item's own history, so treat that number as marketing rather than a real reference point.
