Grinding Paper - Plane Grinding
Our high-quality grinding paper Rhaco Grit can be used for plane grinding of all types of materials. However, it is the best choice for grinding soft and ductile materials. Rhaco Grit provides a long lifetime as well as good planeness and edge retention. Rhaco Grit P120-P320 is recommended for plane grinding. These grit sizes are based on Al2O3 which means that the lifetime is 2-3 times longer, providing at least 100% higher material removal compared to regular SiC Paper.
When Rhaco Grit is used with our unique Aka-Rhaco, it can substitute the expensive PSA or foil backed grinding papers. Aka-Rhaco is a thin steel disc with a soft polymer coating to hold grinding paper. Aka-Rhaco can last for up to 1000 applications and is optimised to be used with our Rhaco Grit grinding paper. However, Aka-Rhaco can be used with most types of plain-backed grinding papers.

Why is grinding paper the optimal choice for soft and ductile materials?
For very soft and ductile materials, diamond grinding discs can get clogged and will eventually stop removing material. Then grinding paper is the better choice, also because grinding paper is exchanged frequently.
How do I convert the grit sizes you use (FEPA P) to ANSI (American Standard) or the actual grain size?
