The most efficent grinding tools on the market! HTC's four series of tools, covering all types of concrete grades,

Mohs Scale - Choose the right tool with HTC's hardness tester
By means of a simple scratch test, you determine the hardness of the floor
or the concrete in relation to the Mohs Scale. Start with the lowest numbers
on the scratch sticks and then work your way up until you scratch the floor.
When you have obtained the value from the scratch stick, use the SMHX
table below to find the tool series HTC recommends for the
floor you want to grind.
