Diamond blade for micro-trenching: how to choose?
Choosing the right diamond blade for micro-trenching is crucial. Today, we'll analyze the key features to consider. Not all products on the market are truly efficient for this type of operation.
Microtrench: clean excavation with diamond discs
First, it's important to understand the fundamental difference between a micro-trench and a mini-trench. A micro-trench is an excavation in the road surface 3 to 2 cm wide and up to 35 cm deep. These dimensions are required by large fiber optic installation contractors . The smaller size of this type of excavation ensures clean restoration without creating excessive depressions for municipal administrations.
Diamond blades for micro-trenching, unlike PCD or carbide blades, guarantee a clean cut. What do we mean by clean cut? First, it means a trench that doesn't require excessive trench clearing. Second, the diamond blade abrades the asphalt surface, leaving solid, clean cutting edges. This feature is essential to prevent the road surface from collapsing into the trench during work. Furthermore, a solid edge helps better consolidate the repair chemicals.
Diamond blade trench digging: the benefits
We can therefore summarize the benefits of micro-trenching with specific diamond blades. These points should be compared to traditional excavation methods using blades and pick-shaped blades.
- Better excavation cleaning
- Faster cutting speed
- Better post-processing consolidation
- Dust reduction through wet use
- Use with light machines (joint cutters)
Diamond wheels for laying optical fiber
What's the best diamond blade for micro-trenching for fiber optic installation? You're probably aware that large contractors require very different excavation methods. This depends both on the client's requirements and the type of excavation required. Digging trenches with a diamond blade is usually optimal for short distances and minimal thicknesses.
The diamond blades used today are:
- Ø450 mm with 25.4 + T hole with cutting thickness: 10, 15, 20 mm – maximum cutting depth: 17.5 cm
- Ø500 mm with 25.4 + T hole with cutting thickness: 10, 15, 20 mm – maximum cutting depth: 20.0 cm
Where to find them? Nord SRL has been producing diamond wheels and blades for cutting asphalt and joint cutters since 1960. Today, we offer specialized products for micro-trenching with excellent performance in terms of durability and cutting speed.
Contact us at sales@lanordsrl.it to find out where you can find retailers for our specific products, or to get more information directly from the Italian manufacturer.
In microtrenching, the consistency of the cut also depends on the correct calculation of the peripheral speed .
Custom-made and rechargeable tools
Thanks to the constant and evolving demands of our clients, we produce custom diamond blades for micro-trenching. These special tools obviously require solid, high-performance machines. Below are some very interesting examples:
- Ø600 mm with hole 25.4 + T with cutting thickness: 10, 13, 15, 20 mm – 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 diamond blades for micro-trenching are manufactured entirely in Italy at our own production facility. This advantage allows us to produce custom-sized diamond blades for unique and specific requests within reasonable lead times.
