Diamond grindstones can be divided into two types according to their surface conditions:

One is the breakpoint surface grindstone. The so-called breakpoint surface, the surface of the grindstone is not a continuous and complete diamond plane, but a series of regular and continuous circular holes or very narrow grooves on the surface, which are slightly recessed under the plane. The function of these round holes is to let iron filings into them during the grinding process, so that the grinding surface is not disturbed.

The other is a continuous surface grindstone, which is more suitable for grinding narrow or point-shaped cutting edges, because such cutting edges may get stuck in the breakpoint of the broken surface grindstone.

The size of diamond grindstone is similar to that of terrazzo, including four sizes of 2x6", 3x8", 4x10" and 3x12".

The mesh number of the grindstone starts from the thickest 180 mesh (70 microns) to the finest 8000 mesh (3 microns).

Why choose diamond?


One of the main reasons why I like to use diamond grindstones is the durability of diamonds. If you accidentally drop the diamond grindstone on the concrete floor, it will generally not break, but the terrazzo or whetstone will not be so strong.


There is no need to worry about damage to the surface of the diamond grindstone, whether it is accidentally poking the edge or tip of the grindstone or the tool hits the corner of the grindstone. The best thing about diamond grindstones is that they will never be dented.


The grinding efficiency of diamond grindstone is very high. Under the same mesh, diamond grindstone can grind faster than terrazzo. Diamond grindstone can not only grind high-speed steel but also hard alloy. All in all, this means that you can grind more types of metals, and you can grind tools faster and improve work efficiency.

The frequency of use of the grindstone directly affects the life of the grindstone, but the life of the diamond grindstone is very long. For four and a half years, Carl Duguay basically used a grindstone to sharpen the cutting edge of his tools every other week. Up to now, these tools are still very useful. Although diamond grindstone is obviously more expensive than terrazzo, its long service life has significantly improved its cost performance.

Diamond grinding stones require almost no maintenance. The use of diamond grindstones does not require lubricating oil. Generally, water is used as lubrication. Of course, you can also use a grinding fluid specially designed for diamond grindstones. The effect is similar to water, but it will not rust the metal substrate of diamond grindstones.

Don't use things like WD40 and mineral oil, because they are too viscous and will make you spend more extra effort to press the tool when grinding to ensure the grinding effect. After using the grindstone, it will be cleaned briefly to keep it clean and dry. Sometimes, you will see some sticky iron chips on the surface of the diamond grindstone. Don't worry, you can easily wipe off these things with an eraser.
