Thanks to high rotation speeds and a wide selection of blade types, KDS diamond saws excel across multiple applications. Available saw blades include options for natural stone, granite, concrete and reinforced concrete, asphalt, plastics, wood, foil, and aluminum.
From urban trenching to precision demolition and high-performance recycling, the KDS Diamond Saw offers a rugged, reliable, and cost-efficient solution for today’s demanding contractors.

Project Overview: Urban Trenching Challenge in Pordenone, Italy
In Pordenone, Italy, a micro trenching contractor faced the demanding task of cutting 15 meters through a complex mixture of asphalt, concrete, rock, and light backfill. The jobsite required shallow yet precise horizontal trenching with minimal disruption to the surrounding area, especially given the variability in material strength ranging from 10 to 170 MPa.
The Smart Choice: KEMROC KDS 30 Mounted on CAT 306
To meet the challenge, the team selected the KEMROC KDS 30 excavator attachment, mounted on a CAT 306. The combination offered an ideal solution for tight urban environments, enabling fast, efficient trenching without the high noise and vibration associated with traditional equipment like floor saws or asphalt milling machines.
Game-Changing Blade Technology
KEMROC introduced a prototype diamond rock cutting machine blade, 800 mm in diameter and 20 mm wide, perfectly tailored for microtrenching. The blade allowed horizontal cuts at a depth of 300 mm, with productivity hitting an impressive 18–20 linear meters per hour. Even more notable was the blade’s durability, estimated at 1.5 km lifespan per blade, with minimal wear during the entire project.
More Flexibility, Less Overhead: KEMROC’s Economical Alternative to Traditional Trenching
To ensure minimal environmental impact and enhanced safety, water was actively used on-site to suppress dust during the trenching operation. Operators quickly recognized the advantages of the KEMROC KDS 30 Diamond Saw, particularly its low-vibration and low-noise performance, features that are often only associated with indoor floor saws.
What truly sets the KDS 30 apart is its unmatched ability to deliver high performance in challenging outdoor trenching conditions, while significantly reducing project costs. Compared to conventional cable trencher machines and asphalt removal tools, KEMROC Diamond Saw KDS 30 offers a cleaner, quieter, and far more economical alternative. The cost difference is not just noticeable, it’s tremendous. For contractors who prioritize efficiency, the KDS 30 dramatically cuts down overall project expenses, thanks to its reduced maintenance needs, minimal wear on the host machine, and extended blade life. With exceptional cutting precision and lower operational costs, KEMROC Diamond Saw has quickly become the go-to smart solution for operators and project managers seeking both performance and profitability.
In fact, the KEMROC KDS Diamond Saw proved to be a game-changer on site. Its innovative design and cutting-edge technology allowed for efficient horizontal trenching in mixed materials, including asphalt, concrete, and light rock, without the disruption, downtime, or excessive maintenance associated with traditional methods. For contractors seeking high productivity, low environmental disturbance, and long-term operational savings, KEMROC truly stands out as the ‘smart’ solution in the world of excavator attachments.

Why KEMROC? Faster, Smarter, Cost-Effective
Contractors cited several reasons for choosing KEMROC over other brands:
- Lower maintenance and higher utilization
- Significantly improved productivity
- A revolutionary new way of microtrenching in Italy
- Consistent, precise results through hard rock, asphalt, and concrete
- Low price per linear meter
