What the Best Contractors Look for When Sourcing Diamond Blades for Fiberglass Cutting
December 24, 2019

Diamond blades for fiberglass cutting are renowned for speeding up working time by a significant margin.


Working with fiberglass can be notoriously tough, as an industrial material it is highly resilient to blunt and cutting forces.


For this reason, contractors are left at the mercy of the toughest and highly-durable cutting blades to deliver clean and precise cuts. The biggest hurdle for workshops in utilizing diamond blades to meet this demand is their upfront investment. For those who have understood how this increase in productivity can lead to unprecedented returns and worksmanship, the next step is to educate yourself on the details the best contractors look out for when sourcing the best diamond blades.



Diamond blades for fiberglass cutting require a specific blade thickness that is pertinent to the volume and thickness of the fiberglass in question. Blade thickness determines revolutions per minute (RPM); a smaller blade with just enough width will cut through fiberglass rapidly (high RPM), the tradeoff coming in that it will wear down its diamond grit quickly. A bigger blade with a larger width can cut through a higher quantity of fiberglass but it might not be suitable for precision applications.


Diamond Particle Grit

This corresponds to the meshes per linear inch of the diamond granule particles found in diamond blades for fiberglass cutting. Similar to sandpaper, diamond cutting blades have particle grits - the bigger the grits the more aggressive the material removal. Caution, however, isn’t to be thrown to the wind, increased grit size risks a higher probability of material micro-damage or inaccurate cuts, leading to chipping. Smaller grit will lead to more cutting time but will pave the way to ensuring fine, accurate cuts.


Bond Hardness

The bond strength holding the diamond grit against the cutting blade plays a huge role in its performance. A harder bond will improve diamond retention and even improve the blade's overall lifespan; however, the thicker bond will slow down the blade's RPM.


Manufacturer Reputation

Lastly, all diamond cutting blades are made differently. Before landing on a purchase, all previous details are for naught if you don’t work alongside a manufacturer with a track-record of fabricating reliable products. No contractor can afford slowdowns in their fiberglass projects by using subpar diamond blades during operational periods.
