Answering the Three Most Common Questions Surrounding Diamond Cutting Tools
August 20, 2019

Diamond blades show continuous growth in the international market; with an estimated growth of US$1 billion over the next five years, there will naturally be many questions that arise as uptake increases, especially considering the extensive variability and applications that these tools can be used for.


At Graff Diamond, we keep a steady eye on forecasts in the diamond blade market.


In order to prepare for this growth, we have decided to tackle some of the most widespread questions out there surrounding diamond cutting tools – ensuring continued success on your worksite by having the right information.



1) Does Segment Height Affect Blade Life?


Most low cost diamond cutting tools incorporate taller segments into their design so that they give off the impression they are more durable, and have a longer service life than they would otherwise demonstrate from routine usage. We recommend keeping a sharp eye out for visual bronzing on the segment, this shows that a soft bond was used on the peripheries of the diamond tool – resulting in a quicker wearing of the tool.


Ultimately, while segment height can be a respectable barometer for assessing the performance of your blade, there are other, more critical, qualities you should research before considering how well your blade will cut into the material in question. For example, diamond concentration, quality, bonding strength, and size should take precedence.



2) Is a Combination Blade Necessary for Cutting Concrete and Asphalt?


While combination blades can minimise the downtime otherwise seen from switching blades back and forth, reduce the likelihood of damage from misapplication, and are true to their namesake in being used for a combination of tasks, the reality is cutting can be conducted much faster with less blade turnover if blade usage is adapted to each material.



3) Is It Wise to Let Workers Use a Valuable Blade Even If It Might Be Damaged?


The professional consensus is that throwaway blades are much more susceptible to failure at a faster rate than quality blades; diamond cutting tools designed in conjunction with better quality blades are known for their heavier steel core and improved tension – meaning they can handle abusive operations over much longer stretches of time, ultimately resulting in lower costs per cut.

We've always been quite wary of when we use our diamond cutting tools but I was pleased to hear they have lower costs per cut! We'll definitely be using them more often.
