Quick Guide to Diamond Grinding and Polishing Tools

Diamond tools can make or break a job. Whether you’re a Rental House, Dealer, a Contractor, or a DIY user, you should understand a few basic things about the diamond tooling required for polishing concrete to achieve a good finish.  


Here we will discuss the grinding tools for concrete.


Bond refers to the metal or material that holds or binds the diamond pieces to the segment.


There are 3 different types of Bonds: Hard Bond, Medium Bond, and Soft Bond.


Hard: The bond of metallic powder in the segment wears away slowly. Best for soft concrete surfaces. 


Medium: Metal bond strength between soft and hard. Most commonly used.

Hard: The bond of metallic powder in the segment wears away slowly. Best for soft concrete surfaces. 


Soft: The metallic powder in the sintered segment wears away very quickly, releasing dull diamond crystals, and exposing new abrasive crystals. Best used for hard concrete surfaces.


You must pair the appropriate diamond bond with the hardness of concrete you’re working with. Once you figure out the hardness of your concrete you'll be able to figure out which bond strength you'll need. Soft concrete requires hard bond diamonds and hard concrete needs soft bond diamonds. 


Grit Profiles

Grit Profiles are what cause the varying scratch patterns in the concrete. The lower the grit, the deeper the scratches.


We have 6 Grit Profiles: 6, 16, 30, 50, 70 and 100, that are used in sequence to help achieve the appropriate finish.


Each grit is used in sequence to remove the scratch patterns from previous grit until the surface is smooth and free of scratches. Not all steps are always necessary but the more steps followed the smoother the surface potential, which will result in a better polished finished.


Resin Series


When it is time to switch from metal bonds to resins you have to start with Transitional or Hybrid resin tool. This will help to ensure the transition from grinding and smoothing with the metal bonds, to polishing with the resins, is flawless. We have 50 grit and 400 grit transitional (hybrid) resins available.


Similar to metal bond tools, you can build your shine by using increasing Grit resins for each polishing step. The concrete floor will achieve a flawless finish if followed correctly.


Diamond tool is simply one aspect of grinding concrete floors. You should fully understand what the tooling is and how it works, or you will struggling to achieve the polish you’re looking for, or even worse, you could damage your floor.
