Which grit is finer 180 or 300?

The 300 grit sandpaper is finer than the 180 grit. Grit numbers indicate the size of the abrasive particles; a higher number means smaller particles and a smoother finish. Therefore, 300 grit will produce a smoother surface compared to 180 grit, which is more coarse.


Is 30psi equal to 150 grit blasting?

No, 30 psi is not directly equal to 150 grit blasting. PSI (pounds per square inch) measures the pressure of the air used in the blasting process, while grit size (like 150 grit) refers to the size of the abrasive particles being used. Different pressures can produce varying effects on surfaces depending on the grit size, so they are not interchangeable or equivalent measures.


What is the difference between 2000 and 4000 abralon?

There's a about a 6 micron difference between a 2000 and a 4000 grit. Abralon pads are graded using the tighter tolerance FEPA "P" scale. A Abralon "P 2000" grit pad is about 9 microns, which is between 1000 and 1200 USA "ansi" grit. A Abralon "P 4000" grit pad is about 3 microns, which is about a 1500 USA "ansi" grit. Grits can vary a lot, this is do to the different tolerance ranges used by different company's and association's.


What is the difference between 60 and 80 grit sandpaper?

The primary difference between 60 and 80 grit sandpaper lies in the coarseness of the abrasive particles; 60 grit is coarser and removes material more quickly, making it suitable for heavy sanding and shaping. In contrast, 80 grit is finer and provides a smoother finish, ideal for intermediate sanding or preparing surfaces for finishing. The choice between the two depends on the specific project and the desired surface smoothness.
