The only listing here that publishes a grit size

Shark Welding 13067, 4.5 in × 1/16 in, 10-pack

The only disc on this shelf with a published grit size, and the thickest cutting wheel here at 1/16 in — which is a different tool from a 0.045 in disc.

Shark Welding 4.5 inch cut-off wheels in a ten-pack

Shark Welding 13067, 4.5 in × 1/16 in, 10-pack

The only disc on this shelf with a published grit size, and the thickest cutting wheel here at 1/16 in — which is a different tool from a 0.045 in disc.

  • Publishes a grit size — 46 — which no other disc listing in this hub does
  • A 1/16 in thickness, nearly 40 per cent thicker than the 0.045 in wheels here, so it resists flexing in a deep cut
  • No maximum speed published, the first marking this hub names

Best for: Heavier cutting where a thin wheel flexes or wears through too fast

Two things make this listing worth reading on a shelf of commodity discs. It is the thickest cutting wheel here at 1/16 in, where everything else is 0.045 in or 3/64; and it is the only one anywhere in this hub that publishes a grit size, at 46.

Both matter. A 1/16 in wheel is stiffer than a 0.045 in one, which means it tracks straighter in a deep cut through solid bar and tolerates a bind that would shatter a thinner disc — at the cost of a wider kerf, more metal turned to dust and more heat in the work. And 46 grit is a coarse abrasive, chosen for speed rather than finish: it eats structural steel and leaves an edge you would dress before painting.

The listing itself is four lines long: double reinforcement for strength, the abrasive named as aluminum oxide, “10 pk”, “Built to last” — and then a paragraph about the company, which has supplied the automotive aftermarket since 1983 and manufactures in Minnesota. What it does not publish is the maximum speed, which this hub names as the first marking to read, or anything about iron and sulfur. For the price per disc, the fifty-packs on this shelf are a very different proposition; for a thick, coarse, rigid wheel, this is the only one here.

The questions welders ask

What does a published grit size tell me?

How coarse the abrasive is, which decides whether the wheel cuts fast or finishes clean. Forty-six grit is a coarse, aggressive abrasive — it eats metal and leaves a rough kerf, which is what you want on structural steel and not what you want on a visible edge. This is the only listing in this hub, either half, to publish it; every other disc here says "aluminum oxide" or "proprietary grain" and leaves the grit to be discovered in use.

Why choose 1/16 in over 0.045 in?

For depth and rigidity. A 0.045 in wheel cuts faster with less waste and is the right choice for sheet and thin section; at 1/16 in — 0.0625 in — the wheel is stiffer, so it wanders less in a deep cut through solid bar or thick angle, and it survives a bind that would shatter a thinner disc. The cost is a wider kerf, more material turned into dust and more heat into the work. This hub’s buying tip warns against grinding with a cutting disc either way.
