What are cutting discs?The thickness of disc has a crucial impact on speed and quality of cutting. In theory, you can also cut some material with grinding
China cutting disc for metal. The only question is how much power, time and material will you spend. (In the ideal case where angle grinder will not bounce or move to the left to the right during cutting).
The thinner disc is, the cutting is quicker and more accurate, less material is being used, likelihood of sparking is less and considerably lower temperatures are developed. Thickness of 3.00 mm was the standard for years. It was thick enough to withstand safety requirements and lateral straining, but also being thin enough for reasonable cutting. Since the standard grinding discs where manufactured in thickness from 6.00 to 12.00 mm, thickness of 3.00 mm for cutting disc proved to be ideal former production capabilities.
As technology of abrasives progressed, innovation began, so the thickness of
low price disc for metal decreased to 2.5 mm, 1.9 (1.8) mm, 1.5 mm, 1 mm and 0.8 mm. Today, all discs produced by the leading European and world manufacturers are safe for use in any thickness, and there is no reason for the mistrust that still exists towards thin cutting discs. Two protective safety nets are minimum prescribed by European and world standards, but some manufacturers made a step further by producing discs with three safety nets..cutting steel sheet with angle grinder
The advantages of thin cutting discs (1.00 mm thick) as compared to the classic (3.00 mm thick)
- wearing off less material
- cut thickness from 1.05 to 1.3 mm versus 3.15 to 3.50 mm
- less vibrating
- less heating of material
- less sparks
- producing less odor
- faster cutting - higher productivity
- the worker does not need to use a lot of strength when cutting
- easier to control cutting
The advantages of the classic cutting blades (3.00 mm thick) as compared to thin cutting discs (1.00 mm thick)
- slightly longer lifetime (depending on the manufacturer)
- habits
- lower price
Lower prices of thicker dicss can depend on local factors - and these are primarily market requirements and policies of local suppliers. On the European market there is no difference between the price of thinner and thicker discs. If there is difference, it is in favor of thinner discs, which is logical as it is less material needed to produce it. Therefore, if someone wants to sell you thiner

The difference of 2 millimeters per cut it doesn't seem a lot at the first sight. But if someone makes 250-500 cuts a day, 200 days a year, you get a calculation that between 100 to 200 meters of pipes, profiles, rods, sheets of steel, stainless steel etc. per year is literally turned to dust.
