Diamond blade for micro trenching: how to choose?
Choosing the right diamond blade for micro trenching is essential. Today we analyze together what are the fundamental characteristics to take into consideration. In fact, not all products on the market are actually efficient for this process.
Microtrench: clean excavation with diamond discs
First of all, it is important to understand the fundamental difference between micro-trench and mini-trench. In fact, the micro-trench is an excavation on the road surface with a width of 3 to 2 cm and a depth of up to 35 cm. These dimensions are required by large contractors for the installation and laying of optical fiber. The small size of this type of excavation guarantees clean restoration without creating excessive depressions for municipal administrations.
Micro-trench diamond blades, unlike PCD or hard metal blades, guarantee a clean cut. What do we mean by clean cut? First of all, a trench that does not require excessive work to empty the trench. Secondly, the diamond blade abrades the asphalt surface leaving solid and clean cutting edges. This feature is essential to prevent the road surface from collapsing inside the trench during processing. Furthermore, a solid edge helps a better consolidation of the specific chemical substances for restoration.
Diamond Disc Trenching: The Benefits
We can therefore summarize the benefits of micro-trenching with specific diamond discs. These points must be compared to traditional trenching methods with blades and spike discs.
- Better excavation cleaning
- Faster cutting speed
- Better post-processing consolidation
- Dust reduction through wet use
- Use with light machines (joint cutters)
Diamond discs for laying optical fibre
What is the best diamond blade for micro trenching for laying optical fiber? You surely know that large contractors require very different excavations. This depends both on the client's request and on the type of excavation required. Digging trenches with a diamond blade is usually optimal for short distances and minimum thicknesses.
The diamond discs used today are:
- Ø450 mm with hole 25.4 + T with cutting thickness: 10, 15, 20 mm – maximum cutting depth: 17.5 cm
- Ø500 mm with hole 25.4 + T with cutting thickness: 10, 15, 20mm – maximum cutting depth: 20.0 cm
Where to find them? Since 1960, Nord SRL has been producing diamond wheels and discs for cutting asphalt and for joint cutters . Today we offer specialized products for micro-trenching with excellent performance in terms of duration and cutting speed.

Microtrench: custom diamond blade and refill
Thanks to the continuous and changing requests of the client companies, we have produced custom diamond discs for micro trenching. These special tools obviously require solid and high-performance machines. Below you will find some very interesting examples:
- Ø600 mm with hole 25.4 + T with cutting thickness: 10, 13, 15, 20mm – maximum cutting depth: 25.0 cm
- Ø650 mm with custom hole. Cutting thickness: 10, 12, 13, 15 mm – maximum cutting depth: 27.5 cm
- Ø800 mm with custom hole, cutting thickness: 15, 20 mm – maximum cutting depth: 35.0 cm
All La Nord SRL micro-trench diamond blades are produced entirely in Italy at our production plant. This advantage allows us to produce a diamond blade with ad hoc measurements for unique and specific requests in reasonable timeframes.
