Frequently asked questions about the Grinders category
What are Grinders (sanders) and what tasks are they for?
Grinders (sanders) are power tools for sanding, polishing and finishing surfaces. The category includes models for wood, concrete and metal as well as wall-and-ceiling sanders, offering various power ratings, pad sizes, speed controls and dust extraction options.
Which sander is best for walls and ceilings?
Choose a dedicated wall-and-ceiling sander with a large 225 mm pad, variable speed and dust extraction (e.g., Mirka LEROS 950CV or Stanley SFMEE500S 750W 225mm). These deliver even sanding and are designed for vertical work.
Which sander is suitable for wooden floors and parquet?
Drum and orbital sanders with variable speed and soft operation are suitable for wooden floors and parquet, allowing use of fine-grit abrasives. The range includes eccentric and belt models designed for careful removal and finishing.
Which models are intended for concrete grinding?
Concrete requires powerful grinders with abrasive discs or diamond blades and robust construction for heavy loads. The category includes professional machines with reinforced plates and dust extraction for both rough and finish grinding.
Which sander fits wood and metal work?
For wood use orbital and belt sanders with speed control; for metal use angle grinders with metal-specific grinding discs such as Novipro 230x7x22mm or 125x6x22mm. Always match disc type and RPM to the material.
How to choose between orbital (vibrating), random-orbit and belt sanders?
Choose by task: vibrating (orbital) for fast coarse sanding of flat areas; random-orbit for fine finish with minimal marks; belt sanders for heavy material removal and leveling. Consider pad size, power and speed control.
Is dust extraction necessary and what options exist in the category?
Yes, dust extraction is recommended for large jobs and cleanliness. The category offers models with built-in dust boxes, connections for industrial vacuums and hose ports — choose based on compatibility and dust volume.
What power and speed parameters matter when choosing a sander?
Consider surface size and material: concrete and heavy use need high power and stable RPM; delicate wood benefits from variable speed and lower power (around 100–400 W). Also check for soft-start and RPM control.
Which abrasive discs and sizes suit different tasks?
For metal use NOVIPRO discs 230x7.0x22mm, 125x6.0x22mm or 115x6.0x22mm; for parquet and floors use fine-grit sheets/circles; for concrete use coarse abrasives or diamond discs. Match diameter and bore to your machine model.
Can a cordless random-orbit sander be used for small repairs?
Yes, cordless random-orbit models like DEWALT DCW210N are suitable for small repair and finishing jobs due to mobility and adequate power. Check battery capacity and spare batteries for longer tasks.
