Which Grinding Wheel Should I Choose? | Norton

For this reason, finer grit sized wheels are required to grind hard materials and soft materials are best ground with medium to coarse grit size wheels. For most efficient operation, the grade must be adjusted to suit the hardness of the material. As a general guide, the harder the material, the softer the grade of wheel required.

How to Select the Right Flap Disc for Your Project

Flap discs are almost always used on right angle grinders, and they are applied to your work at an angle or parallel to it. Flap discs are available in two shapes: conical or flat-shape. Conical flap disc: Conical flap discs are your best friends when you need to remove a lot of material in a small amount of time.

Pepper Mill vs. Salt Mill: What's the Difference?
