This twin pack is for professionals and serious DIYers tackling metal fabrication, construction, and masonry work. Its key benefit is providing two versatile angle grinders with different capacities and a universal diamond blade for efficient material cutting. A potential caveat is that the powerful nature of these tools requires careful handling and appropriate safety measures.

The pack includes a 115mm mini angle grinder (G12STX) suited for more detailed work and lighter tasks, and a larger 230mm angle grinder (G23ST) designed for heavy-duty cutting and grinding on larger materials.
The 230mm Universal Diamond Saw Blade is primarily designed for cutting hard, brittle materials like tiles, stone, brick, and concrete. It is not optimized for cutting metal. Use appropriate metal cutting discs for metal applications.
This feature on the G12STX prevents the tool from starting automatically if the power supply is interrupted and then restored. You must manually turn the switch off and then back on to restart the tool, preventing accidental startup.
Always use the 3-position side handle for better control, wear appropriate personal protective equipment (PPE) including safety glasses, gloves, and hearing protection, and ensure the spindle lock is engaged only when changing discs. Never force the tool.
The G12STX uses 115mm (4.5 inch) diameter discs with an M14 spindle thread.
The G23ST uses 230mm (9 inch) diameter discs with an M14 x 2 spindle thread.
The 230mm grinder has features like halved stator coils for better cooling to support longer use. However, for very demanding, continuous operations, it's always good practice to allow the tool to rest and cool periodically to maximize its lifespan.
Check if the power cord is securely plugged into a working 240v outlet. Ensure the on/off switch is in the correct position. For the G12STX, verify that the no-voltage restart protection has not been triggered (unplug and re-plug). Check the power outlet with another device.
The accessory (disc/blade) may be worn or dull; replace it with a new one. Ensure the correct accessory for the material is being used. Check for any blockages in the ventilation slots that might be causing overheating and power reduction.
Ensure the grinding disc or blade is correctly and securely mounted. Check for damage or imbalance in the accessory. If vibration persists, the tool may have internal issues; discontinue use and contact support.
Allow the tool to cool down by running it at no-load for a few minutes. Ensure ventilation slots are clear of dust and debris. Reduce the load or duration of continuous operation if necessary, or consider using a more powerful tool for the task.
