Description
Mohs hardness is a scale that measures the relative hardness of minerals, ranging from 1 (softest, talc) to 10 (hardest, diamond). It determines hardness by comparing the ability of minerals to scratch one another, offering a simple method to test material hardness. This is particularly useful for concrete grinding projects, as it helps in selecting the correct bond type for concrete grinding diamond tools.
This Mohs hardness test kit is ideal for selecting the right diamond grinding tool for your application. It includes 4 double-ended picks with 8 points representing Mohs hardness levels 2 through 9. You can determine the hardness of your floor or concrete by performing a simple scratch test, starting with the lower numbers and gradually moving up the scale until a scratch is made.
