Güde GSK 140/420 Stone Splitter – Precise Cutting up to 140 mm
The Güde splitter offers precise cutting thanks to its manually assisted configuration. The operator has complete control over the cutting process, ensuring straight and clean lines on fragile and precious stones where errors are costly.
The integrated transport frame allows for easy movement of the machine between worksites. The cutting height is adjustable via a central spindle, accommodating thicknesses from 25 to 140 mm without requiring slow tool changes. Low maintenance (no motor, no fuel) ensures constant operational efficiency.
This machine is suitable for construction, renovation, and restoration work where the precision of direct stone cutting determines the final quality of the work. Its low weight (38.1 kg) makes it portable by hand on stable surfaces.

Frequently Asked Questions
What kind of stone material can I cut with the GSK 140/420?
The machine is suitable for soft and semi-hard natural stones: granite, marble, limestone, sandstone, slate, curb stones. Not suitable for extremely hard metamorphic rocks (gneiss, very compact basalt). Verify the specific hardness of the stone.
- Soft: Limestone, sandstone, gypsum (ideal)
- Medium: Granite, marble, slate (suitable)
- Hard: Basalt, gneiss (consider diamond blades)
How much physical effort does manual cutting require?
Assisted loading significantly reduces effort compared to traditional methods. For an operator with average experience, a single cut takes 2-5 minutes depending on the hardness and thickness of the stone. The machine's height (1,435 mm) is ergonomic for prolonged work.
Does cutting produce dangerous dust?
Yes, free cutting produces dust (silicosis hazard). Always use respiratory protection (FFP2+ with valve). The machine can be combined with an external dust extraction system (not included).
Can I transport the machine by myself?
Yes, the net weight (38.1 kg) is transportable by a single operator for short distances or gentle ramps. The integrated transport frame facilitates movement. For frequent movements or rough terrain, we recommend the support of a second operator.
Which blade should be used for marble vs. granite?
Standard Güde blades work well on marble and limestone. For granite and harder stones, use specific diamond blades that maintain sharpness longer and reduce vibrations. Available as a separate accessory.
How do I perform routine maintenance?
Regular cleaning of stone dust; visual inspection for blade cracks before each use; occasional lubrication of articulation points. It does not require periodic maintenance like motorized machines. Inspect the adjustment spindle for wear.
