Virginia Abrasives 14-Inch Concrete Cut-Off Wheel (10-Pack)

The Virginia Abrasives 14-inch concrete wheel is a Type 1 reinforced abrasive disc for cutting concrete, block, and masonry on a 20mm-arbor saw. It is not a diamond blade, and on concrete that distinction decides the money. Buy this wheel for occasional work. For anything ongoing, the VA 14-inch Ultra Value diamond blade at $69.99 is the cheaper tool, and this page is not going to argue otherwise.

Who this wheel is for

Crews whose concrete cutting is occasional but recurring: a plumbing contractor who cuts a slab a few times a year, a fence crew that has to get through a footing now and then, a shop that keeps a 20mm-arbor saw for the odd cut. Ten wheels at $119.56 get used up over a year, and no diamond blade sits in a truck box.

For a true one-off, read the arithmetic below before you order, because the diamond blade costs less at checkout.

The economics, with the arithmetic visible

Here is the whole case in three numbers. This 10-pack is $119.56 at checkout. The VA 14-inch Ultra Value diamond blade is $69.99 at checkout. Our published break-even against diamond is about 20-30 total concrete cuts.

So for one job, the diamond blade is the cheaper purchase by about $50, and it is still cutting afterward. The pack wins only when you will use most of it: once all ten are consumed the wheels cost about $12 each, and a crew that makes a handful of cuts a month spends less that way than it would on diamond blades it rarely needs. A crew cutting daily clears 20-30 cuts inside a week and should be on diamond from the start. Full detail is in Diamond vs Abrasive Cut-Off Wheels.

Lost diameter is lost depth

This is the failure mode that surprises people, and it isn’t a quality problem — it’s how bonded abrasive works. The wheel cuts by wearing away. A fresh 14-inch wheel gives you the full depth the saw is rated for. Three-quarters of the way through that wheel you’re spinning something closer to 11 inches, and the depth you could reach on the first cut is simply gone.

For scoring and shallow work that hardly matters. For a full-depth slab cut, an expansion joint at a specified depth, or a flush cut around a penetration, it matters a lot, and it’s the reason the site recommends diamond for depth-critical work regardless of volume. A diamond blade holds its diameter until the segments are spent.

What we have not tested

We have not run this wheel on a job. There is no cuts-per-wheel number, no linear-foot figure, and no head-to-head wear test on this page, because we don’t have one we measured. What we have is VA’s specification and verified Amazon data as of 2026-08-15: $119.56, 3.6 stars, 4 ratings. Four ratings is not a signal. Do not read it as one in either direction.

Our published category guidance for 14-inch abrasive on concrete is 15-40 shallow scoring cuts per wheel, dropping to as few as 1-5 at full depth. That range comes from our 14-inch cut-off wheel roundup and describes the category, not this part number.

Construction and fit

Spec	Figure
Diameter x thickness x arbor	14” x 1/8” x 20mm
Wheel type	Type 1 (flat), reinforced
Bond	Resinoid, fiberglass reinforced layers
Grain	Silicon carbide
Pack	10 wheels, $119.56 at checkout (about $12 a wheel once all ten are used)
Rated materials	Concrete, block, masonry

The 20mm hole is the fit constraint and it runs one way only. It seats on a Stihl TS 420 or TS 500i and a Husqvarna K 760, K 770, or K 970 with no bushing. It will not go over a 1-inch arbor, which is what most US chop saws run — the hole is smaller than the shaft, so the wheel physically won’t mount. Measure your spindle before ordering, because a 10-pack is a lot of wheels to own for the wrong saw.

Silicon carbide is the correct grain for concrete and masonry, and the resinoid bond microfractures as it works, breaking down to expose fresh cutting edges rather than polishing over. That’s what keeps an abrasive wheel cutting, and it’s also why the wheel gets smaller every minute it runs.

Dust, water, and the safety items

No wet cutting. Resinoid bonds are not rated for it and water weakens them over time. That pushes you into dry cutting, and OSHA Table 1 lists water fed to the blade as the only control for a handheld saw on concrete, so a dry cut takes the employer out of Table 1 and into an exposure assessment. Wet cutting with a diamond blade is the Table 1 path, and it’s a real argument for diamond that has nothing to do with cost. Our silica dust safety guide covers what inspectors actually check.

Read the RPM rating on the wheel. The listing doesn’t publish one. The printed rating is authoritative and an illegible label means the wheel doesn’t get mounted.

Check the date stamp before each use, and retire anything past roughly two to three years from manufacture.

Guard down, no side-load, clamp the work. Abrasive cracks under lateral force more readily than diamond does.

Honest summary

Your situation	What to buy
One repair, no repeat work expected	VA 14” Ultra Value diamond, $69.99 at checkout: less than the pack, and it keeps cutting
Occasional but recurring cuts on a 20mm-arbor saw, well under 20-30 cuts per job	This wheel, $119.56 / 10-pack, used up over a year
Ongoing concrete, 20-30+ cuts	VA 14” Ultra Value diamond, $69.99
Depth-critical cuts at any volume	Diamond — abrasive loses depth as it wears
Exposed steel and rebar stock	VA 14” metal cut-off wheel, $79.99 / 10-pack

Disclosure

Matt Lipman is CEO of Capstone Holdings Corp. (NASDAQ: CAPS) and a board member of Virginia Abrasives. He discloses this relationship on every page that recommends a VA product. VA sells both products compared on this page, and our answer for ongoing concrete cutting is still the diamond blade rather than the wheel, because that is what the per-cut math says.
