Grinders
How to choose grinders
Disc size
Disc size drives capability: 115mm or 125mm for light tasks, 230mm or 9-inch for heavy removal.
Power source
Power source splits the range: corded for steady work, air if you have a compressor, brushless unit if you own batteries.
Body material
Body material changes feel: aluminium and composite save weight, steel adds site toughness.
Motor build
Motor build matters: copper coil corded suits long loads, brushless gives efficiency with less care.
Substrate match
metal/wood tools handle mixed materials, dedicated metal grinders focus on steel and stone.
What's good
- Corded angle grinders with copper coil motors deliver constant power for long cuts, with no battery to fade.
- Air die grinders in composite or aluminium bodies are light, letting you reach tight corners without arm strain.
- Brushless cut off tools run cooler and need no brush changes, suiting users who want low upkeep.
- Large 230mm or 9-inch disc machines clear thick steel or masonry faster than 115mm units.
- Stainless steel or aluminium bodied tools shrug off rust in damp sheds better than plain steel.
Things to watch
- Corded electric grinders need a nearby socket, which restricts movement when working on cars or outdoors.
- Air angle grinders require a compressor, so setup is noisy and tied to another machine.
- Small 115mm grinders cannot cut deep enough for thick bar or slab, leaving you stuck mid job.
- Brushless unit-only tools often ship without battery or charger, useless if you lack the platform.
- Narrow 10mm by 330mm belt sanders are slow on wide areas, wrong for big flat surfaces.
Care & maintenance
Clean bodies
Wipe aluminium and stainless bodies after use to keep dust from clogging vents.
Check brushes
Inspect carbon brushes on corded grinders, or pick brushless to avoid that check.
Service air tools
Lubricate air tool internals and drain compressor water to stop freeze ups.
Store consumables
Keep discs and belts dry, especially for metal/wood rated items that warp with moisture.
