Welcome back to 'Ask the Expert' and this time Norton Application Engineer Paul answers a very common question, how to choose the right coated abrasive grit for the job? As Paul explains, the choice of grit depends on the metal you're working on. If you're grinding carbon steel, it's better to start with a more coarse grit like 40 to remove welds and scale from the metal before moving on to grit 60. You could also use a grinding wheel on carbon steel, such as the Norton Quantum3 Light Comfort Grinding (LCG) wheel.

For stainless steel where a better, smoother finish is usually needed, start with a finer grit, like 80. This will achieve a flat finish which is easier and faster to polish out. Using too coarse a grit will result in lots of scratches as the steel is a softer metal which will take much longer to finish.
