Specifications
Benefits
The electric motor of the RURIS RA850 model offers significant benefits, being both powerful and efficient. It operates smoothly and consistently, providing optimal power without interruptions, which is crucial in projects requiring precision and constant speed. Additionally, this type of motor is easy to maintain, quieter, and more environmentally friendly, contributing to a comfortable, clean, and efficient work environment.
The 850W power allows it to easily handle demanding tasks, such as quickly cutting thick metals and precisely grinding hard surfaces.
Thanks to its 850W, users can work efficiently without the risk of overheating or power loss, ensuring continuous workflow and professional results in a shorter time.
The no-load speed of the RURIS RA850 angle grinder of 11,000 rpm is optimal, as it ensures precise and fast cutting, even in hard-to-reach areas.
Advantages
The cutting disc diameter is 125 mm. Discs of this type are excellent for fine cuts, detailed adjustments, and finishes, providing better control and increased maneuverability compared to larger diameter discs. Thus, the RURIS RA850 is an extremely efficient tool for precise tasks, both in DIY workshops and on construction sites.
Additionally, due to its 125 mm diameter, the grinder is easier to handle, being more compact and lighter than models with larger discs. This feature reduces user fatigue and makes the tool suitable for extended use or for tasks requiring flexibility and precision. On top of that, it offers low vibration levels.
The soft grip handle is designed to absorb vibrations and reduce hand fatigue, allowing for a firmer and safer grip on the tool even during prolonged work or when the grinder is used in challenging environments.
The tool includes a diamond cutting disc for metal cutting.
Changing the disc can be easily done using the central spindle lock button.
The protective guard is designed to shield the user from any material fragments, sparks, or debris expelled during cutting or grinding. It also prevents accidental contact with the cutting disc during operation, significantly reducing the risk of accidents.
Moreover, the guard can be adjusted for optimal protection, regardless of the angle at which the grinder is used. Safety and comfort are enhanced by the option to position the handle in either of the two working positions.
The Power Off system automatically stops the grinder in case of a power interruption or overload, protecting both the equipment and the user.
One of the main advantages is preventing accidental restarting of the grinder when power is restored. Thus, the power-off system eliminates the risk of accidents caused by an uncontrolled sudden start, making the tool much safer to use, especially in demanding work environments.
