Your Guide to Diamond Hole Saws
May 13, 2020

If you work with a lot of porcelain, ceramic, slate, marble, stone, fibreglass, granite, and glass materials, you most likely utilize a diamond hole saw to help with the cutting process. If you are planning to use or are already using one, it is helpful to know how drill speed, pressure, and lubrication can affect the cutting speed and lifetime of the saw. Determining the optimum parameters for these factors will help you get the fastest cutting speed that will have the least effect on the hole saw’s life, lessening the risks of breakage.


If you don’t have enough experience yet with a diamond hole saw, it is advisable that you begin with a very low pressure, slow speed, and plenty of lubrication. This will help minimize any potential risks associated with this cutting tool. Careful maintenance of your saw is key, and how well you take care of it will determine how easy and smooth your cuts will be.


When it comes to the hardness and abrasiveness of the material being cut, they vary a lot depending on their specific physical compositions.


For instance, the hardness of glass varies a lot based on its type and colour, depending on the additives used to achieve particular properties. In the case of stones and other natural materials, they also vary by type. Some of them are a mixture of different kinds of rock. Granite, for instance, is composed of different combinations of black mica, quartz, and feldspar. The same holds true with marble. Its hardness and abrasiveness significantly differs depending on the mineral composition it has, which will also affect how you choose the right diamond hole saw for the job.


As such, it helps to refer to a table of the hardness of different materials that uses the standard Knoop Hardness Scale. Of course, the hardest known material is also diamond, with a Knoop measurement of 7,000. Second to diamond as the hardest natural material that exists is tungsten carbide but it only measures about 2,000 Knoops. As such, it is clear that any diamond hole saw will be able to tackle a wide range of applications, though you will still need to adopt the best practices when using your saw to ensure its durability.

Love your diamond hole saw product!
