Angle Grinder GEKO 230 mm — GEKO model with 230 mm disc, geared transmission, arbor sizes 15 mm and 10 mm

Geared angle grinder GEKO with a 230 mm disc is a power tool designed for demanding grinding and cutting operations. The geared (toothed) transmission focuses on delivering higher torque at lower speeds compared to direct-drive models, which makes this 230 mm angle grinder suitable for heavy-duty metal and stone abrasive work, surface preparation and tasks requiring a larger wheel. The tool accepts arbor sizes of 15 mm and 10 mm, offering compatibility with a wider range of cutting and grinding accessories.

Advantages

The geared transmission provides increased torque for controlled material removal and longer life under heavy loads. Using a 230 mm disc enables deeper cuts and wider grinding paths, reducing the number of passes on large surfaces. Compatibility with both 15 mm and 10 mm arbors increases flexibility when selecting discs and cup wheels. The design is intended for stable operation during prolonged use and for applications where torque and wheel size directly affect productivity.

Suitable for

• Cutting thick metal sections and structural profiles
• Grinding and shaping stone, concrete and masonry
• Surface preparation on large metal sheets and welded joints
• Removing rust or old coatings with coarse abrasive wheels
• Tasks that require deep grinding or wide cutting with a 230 mm wheel

Key specifications

• Disc diameter: 230 mm
• Transmission type: geared (toothed) for increased torque
• Arbor compatibility: 15 mm and 10 mm
• Primary applications: cutting and grinding of metal, stone and concrete
• Typical use profile: heavy-duty and prolonged operations requiring torque

How to use

Select an appropriate 230 mm disc or wheel compatible with the tool’s arbor size and application (cutting, grinding or surface removal). Securely fit the wheel following the manufacturer’s instructions for flange and nut tightening; ensure the wheel is compatible with the geared gearbox and rated speed. Use protective guards, hold the grinder with both hands, and apply steady, controlled pressure—do not force the tool. Allow the gearbox to reach operating speed before contacting the workpiece and maintain cooling breaks during prolonged use to avoid overheating. Check the wheel condition regularly and replace worn or damaged discs.

Usage recommendations

Wear appropriate personal protective equipment, including eye, ear and respiratory protection, as well as gloves. Use the correct disc type and grit for the material: coarse bonded wheels for rapid material removal, diamond or segmented blades for stone and concrete cutting, and flap or grinding wheels for surface finishing. Ensure secure workpiece clamping and maintain clear ventilation when cutting or grinding materials that produce dust or fumes.
