Güde GSTM 350 Stone Cutting Machine – 2200W Motor, Ø350 mm Diamond Blade
The Güde GSTM 350 machine is a stable solution for cutting natural stone, marble, granite, concrete, and bricks on construction sites and stone workshops. Unlike manual saws (physical fatigue, inaccuracy) or portable stone cutters (difficult movement), the stationary table allows precise workpiece positioning. The Ø350 mm segmented diamond blade cuts hard materials without excessive chipping, thanks to the calculated peripheral speed: moving the workpiece towards the blade (not freehand) improves control and safety.
The 0–45° continuously tiltable head allows for miter cuts for decorative profiles, angles, and curved shapes without the need for additional tools. The 800 mm cutting length covers almost all common stone sizes (slabs, edges, bases). The 115 mm depth is sufficient for double bricks and medium thicknesses (not for massive blocks >150 mm). The S6 40% duty cycle indicates intermittent use: suitable for construction sites with frequent breaks, not for continuous 8-hour uninterrupted production. Integrated water cooling protects the blade from overheating and reduces airborne silica dust (operator respiratory protection).
Who chooses it in Italy
Construction companies operating temporary sites prefer it for its versatility in cutting natural stone and brick without major investment (compared to pneumatic lathes). Artisans who create decorative elements (sills, cornices, balustrades) request it for precise angles with the diamond blade. Flooring and cladding installers use it for on-site touch-ups (edges, corners, adaptations) without resorting to external services. In the Krollit catalog, it represents the ideal complement for construction sites that require cutting versatility without multiplying specialized tools.
Who is the Güde GSTM 350 machine suitable for?
| Profile |
Suitable? |
Reason |
| Construction contractor / temporary site |
Ideal |
Versatile cutting of natural stone, brick, concrete. 0-45° tiltable head for decorative profiles. 800 mm length covers common sizes. Foldable legs facilitate transport between sites. Diamond blade included. |
| Artisan stone mason / specialized workshop |
Ideal |
Precise angles and miters for decorative elements. Segmented diamond blade reduces chipping. 115 mm depth suitable for medium thicknesses. Water cooling protects the blade. |
| Continuous industrial production |
Adequate |
S6 40% duty cycle is a limit for 8 hours of continuous use. For productions >1,000 pieces/month, consider a semi-automatic or industrial saw. 2200W power is sufficient for repetitive cuts but not for ultra-hard materials without breaks. |
Not suitable for: Massive stone blocks >150 mm deep (undersized machine, blade overheats). Precious marble requiring a mirror finish (diamond wire saw is better). Vertical or angled cuts not supported by a fixed table (custom design). Environments without water drainage (liquid cooling system requires regular discharge).

Frequently asked questions
Can I cut precious marble without chipping with this machine?
Partially yes for modest dimensions. Segmented diamond blades reduce chipping but do not eliminate it completely. For precious marble requiring a mirror finish, a dedicated diamond wire saw (more expensive) offers superior precision. The GSTM 350 is suitable for functional cuts, edges, and on-site adaptations with acceptable quality.
Is water cooling mandatory during cutting?
Strongly recommended. Water reduces blade overheating (prolongs life) and reduces airborne silica dust (operator respiratory protection). Without water, the blade overheats quickly and loses cutting efficiency. Therefore, yes, always activate the water circuit before cutting.
What materials can I cut besides natural stone?
The machine is suitable for: marble, granite, concrete, brick, ceramic tiles, gravel. Not suitable for: metal (steel, aluminum — requires a different metallurgical abrasive disc), wood (diamond disc would leave burn marks). Always check the material before cutting.
Does the soft start system really reduce current peaks?
Yes. Soft start limits the inrush current at startup, protecting the motor and reducing the load on the electrical grid. Without soft start, direct startup of a 2200W motor creates a current peak of ~20 A. With soft start, the peak is limited to ~10–12 A, which is gentler for the meter and other connected tools.
What blade diameter should I use as a replacement?
Always Ø350 mm with a 25.4 mm bore for mechanical compatibility. Güde diamond blades and compatible brands are available in various grit sizes (fine for finishing, coarse for speed). Segmented blades are recommended, like the original, to reduce chipping.
How do I drain the water from the cooling system?
After work: close the water supply valve, open the drain valve on the tank (if present) or tilt the machine slightly to drain by gravity. After 1–2 weeks of inactivity, drain completely to prevent limescale deposits and mold in the water circuit.
Can I cut thicknesses greater than 115 mm by tilting the head?
No. The 115 mm at 90° is the declared maximum depth. Tilting the head to 45° reduces the depth to 72 mm, it does not increase it. Cutting thicknesses >115 mm requires a larger blade (Ø400-500 mm) or a specialized saw.
Does the 90 kg weight make transport between construction sites difficult?
Depends on site logistics. A 90 kg weight requires a forklift or crane for single loads. Folding legs facilitate compact storage in the warehouse. If sites are close (same area), transport with an equipped van is manageable. For dispersed sites, consider two units or local rental.
