Diamond circular saws for:

In diamond circular saws, cutting of the material is succeeded by diamond segments that are precisely welded on the outer periphery of the steel disc blade, under controlled time, heat and pressure. One of the main factors of cutting is to use suitable segments for the material to be cut. While segments wear the stone, the stone abrades the segments as well, so new diamond particles become exposed and the process continues.

DIATOOLS diamond circular saws are available in diameters 200 to 3000 mm in order to adapt their utilization possibilities to different materials and machineries.

DIATOOLS diamond circular saws are widely used in:

- Cutting marble, granite, travertine, limestone;
- Opening grooves in concrete roads;
- Cutting asphalt roads;
- Cutting building floors and walls;
- Installation of power and telecommunication lines without damaging asphalt roads;
- Construction and restoration of airports.

Application recommendations:

  • Cutting rate
    A proper speed must be determined for every single material, since peripheral speed varies with characteristics of the material to be cut. A very low speed results in segments getting dull so the blade will not cut. In addition, a very fast cutting causes diamond particles to burn or break out. In both cases, the saw blades life will decrease considerably. Refer to table I for peripheral speed and rpm values according to saw blade diameters.


Peripheral speed

Cutting rate (cm2/min)


25 - 40

100 - 600


40 - 50

1000 - 5000


50 - 60

1500 - 6000

  • Power requirement
    The motor power driving the main shaft must be sufficient to maintain an optimum performance of the saw blade. Main shaft and saw blade alignment must be proper, that is, it must be ensured that there is no gap between main shaft and saw blades arbor hole. Vertical saw must move in parallels with horizontal saw blade. Also, the material to be cut must be anchored securely. See table II for minimum power requirement.
  • Flange
    The functions of flanges are to tighten the saw blade to the main shaft, to ensure proper alignment of the both and to avoid the saw blade run eccentrically. Flanges must be free of dirt, oil and rust and must be checked periodically. For minimum flange diameters, refer to table II.
  • Cooling water
    The function of cooling water is to cool the saw blade and to wash worn    particles of the material away from cutting zone, so excessive wear on    segment will be avoided. Cooling water must be directed to both sides of      the blade, below flanges and front of the blade, if necessary. Cooling      water must be sufficient and clean. For cooling water requirement, see      table II.
  • Direction of rotation
    The saw blade must always be mounted in the direction of rotation shown on it by an arrow. If the blade is installed reversal on the main shaft, diamond particles on segments will fall down and dullness will occur. A suitable cutting system must be determined for each type of stone. For hard materials such as granite, the step cutting method is recommended.
