Grinding disc 125 mm — from the manufacturer NovoAbrasive
Thick reinforced discs of 6 and 8 mm with a depressed centre (type 27) for cleaning welds, removing burrs and rough grinding of steel, stainless steel and cast iron. Three series: Standard, Profi, Extreme.
Why the 125 mm grinding disc is the basic tool
125 mm is the most common angle grinder size, so a 125 mm grinding disc is found in every workshop, on every construction site and in every plant. The depressed centre (type 27) lets you work with the face of the disc at 15–30° without the nut touching the surface, and the 6–8 mm thickness gives a safety margin for removing welds, chamfers and burrs.
NovoAbrasive makes grinding discs on Davide Maternini (Italy) equipment with grain from Saint-Gobain and Imerys; every batch is tested by the oSa method, and the products are MPA Hannover certified and comply with EN 12413.
6 or 8 mm thick: which to choose
| Thickness | Application | Advantages | For whom |
|---|---|---|---|
| 6 mm | Cleaning welds, removing burrs, chamfers on thin metal | Lighter, more manoeuvrable, finer control | Daily workshop use |
| 8 mm | Heavy stock removal, large welds, cast iron, castings | Longer life and rigidity, less vibration | Construction, industrial plants |
Rule: the more metal you need to remove per pass, the thicker the disc. A 6 mm disc suits grinders up to 1000 W; for tools from 1200 W take 8 mm.
Abrasive and series
Aluminium oxide (corundum)— the universal grain of the Standard and Profi series for structural steel, pipes, profiles and cast iron. Stable wear, predictable life.
Ceramic aluminium oxide— the self-sharpening grain of the Extreme series: the grain fractures in use and exposes new cutting edges, so the disc removes metal faster and keeps its performance longer on stainless and alloy steels.
Series: Standard (NovoAbrasive Standard, Hetman brands) — household and occasional work; Profi (NovoAbrasive Profi, WellCut) — daily professional work, MPA Hannover certified; Extreme — industrial conditions with maximum stock removal.

How to work with a 125 mm grinding disc
- Hold the grinder at 15–30° to the surface: at a smaller angle the disc skips, at a larger one it digs in and leaves grooves.
- Never cut with a grinding disc: it is designed for face loads, not edge loads. Use a 125 mm cutting disc for cutting.
- Work only with the guard and a flange that matches type 27; check that the grinder speed does not exceed 12,200 rpm.
- Inspect the disc for chips and cracks before mounting, then let it run idle for 30 seconds.
