Zirconia alumina resin fibre disc for heavy stock removal on mild and structural steel. Stocked at our Kota counter, dispatched across Rajasthan.
A fibre disc, not a grinding wheel. This is a vulcanised fibre disc: a sheet of zirconia alumina grain bonded with resin over resin onto a stiff fibre backing. It runs on an angle grinder with a rubber backing pad behind it, and it grinds. It is not a depressed-centre wheel and it will not cut.
The difference matters when you are ordering. Fibre discs and backing pads are covered by EN 13743, which is the mark printed on the face of this disc. Bonded grinding and cut-off wheels are covered by EN 12413 instead. If a seller quotes you 'Zirkon 178' without saying which of the two you are getting, ask before you pay.

Knocking down MIG and arc weld beads on structural steel before finishing. Grit 36 is the usual choice; grit 24 where the bead is heavy.
Paint, rust and old weld removal on panels and chassis sections, typically in 100 mm and 125 mm.
Shutdown and breakdown work in cement, thermal and process plants, where a disc that lasts longer means fewer trips back to the store.
Removing runners, risers and parting-line flash from castings. Coarse grits, high consumption, usually bought by the 100.
Edge grinding, plate preparation and dressing after gas or plasma cutting. This is the bulk of what moves through our counter in Kota and Jaipur.
Cutting of any kind, stone and marble work, and sustained grinding on stainless where a ceramic grain will run cooler and last longer. We will say so rather than sell you the wrong box.
Most buyers who call us about 'a fibre disc rate' are really asking whether they are on the right grain. The three grains below cover nearly every job that comes through a Rajasthan fabrication shop.
| GRAIN | NORTON RANGE | BEST ON | RELATIVE COST |
|---|---|---|---|
| Aluminium oxide | Alkon | Light and general-purpose grinding, mild steel, wood. Avoid on stainless — ordinary corundum can leave iron that rusts. | Lowest |
| Zirconia alumina | ZirKon+ | Mild and structural steel, heavy weld removal, foundry fettling. Self-sharpening under pressure, so it suits an operator who leans on the grinder. | Middle |
| Ceramic alumina | Blaze, 3M Cubitron II | Stainless steel, hardened and alloy steels, anything heat-sensitive. Runs coolest and lasts longest. | Highest |
| GRIT | USE IT FOR |
|---|---|
| 24 | Heavy weld beads, casting flash, scale on hot-rolled plate. |
| 36 | General heavy stock removal. The grit most shops order by default — and the one on this disc. |
| 50 / 60 | Moderate stock removal with a cleaner finish; cleaning up after a 24 or 36. |
| 80 | Blending, feathering and preparation before paint. |
| 120 | Finishing passes where scratch depth matters. |
| Properties | FIBRE DISC | FLAP DISC | DEPRESSED-CENTRE WHEEL |
|---|---|---|---|
| Standard | EN 13743 | EN 13743 | EN 12413 |
| Needs a backing pad | Yes | No | No |
| Stock removal | Highest for the money | High | Highest |
| Finish left | Coarse, even scratch pattern | Smoother, blends well | Coarse and uneven |
| Can it cut | No | No | Only a cut-off wheel can |
| Usual reason to pick it | Fast, cheap per disc, easy to change | Grind and finish in one pass | Deep, aggressive grinding on heavy sections |
We stock all three. If you tell us the job rather than the product, we will usually be able to tell you which one works out cheaper over a month.
