An angle grinder in Australia is a handheld power tool that spins an abrasive or cutting disc at high speed to grind, cut, sand or polish metal, stone, tile and masonry, the tool most tradies reach for when a job needs more brute force than a drill or a jigsaw can manage. A disc mounted at a right angle to the motor housing is what gives the tool its name, and swapping that disc between cutting, grinding and flap-sanding wheels turns one body into several different tools.
Two power formats dominate what’s sold to Australian buyers. Corded electric grinders plug straight into mains power, running continuously without ever needing a recharge, the standard pick for a home workshop where a power point is always within reach of the extension lead. Cordless battery grinders trade that endless runtime for the freedom to work on a roof, a fence line or anywhere else a cord becomes a hazard, and increasingly share battery packs with the rest of a brand’s cordless tool range so one battery does double duty.
Disc size is the number that decides what a grinder can actually do: 100mm and 125mm discs cover the vast majority of home and trade jobs in this guide, while anything larger starts moving into heavy fabrication territory most home garages never need. The spec worth checking second is no-load speed in RPM, since a higher-RPM grinder chews through a cutting job faster but also kicks back harder if the disc binds – which is exactly why a grinder with anti-kickback and drop protection built in is worth paying extra for over a bare-bones model.
This guide compares six angle grinders sold to Australian buyers, corded and cordless, from a cheap entry-level model to a trade-grade cordless kit, all built around the common 100-125mm disc sizes. If you’re kitting out the rest of a workshop corner at the same time, our guide to the best hedge trimmers in Australia covers the other side of the shed – the cordless tools that live outdoors rather than at the bench.

How We Picked
We checked general home and garden retailers stocked in Australia first and found no real angle grinder stock among them – the same gap that turns up for most standalone power tools sold outside dedicated hardware chains. From there we built this list entirely from Amazon AU, prioritising a spread of corded and cordless options across five different brands instead of filling slots with near-identical listings.
Star ratings and review counts anchored most of the picks, from Makita’s 7,000-plus review base down to newer entries with a handful of ratings so far – we’ve flagged the sample size honestly on each entry instead of treating every star rating as equally proven. We don’t physically test every grinder ourselves, and commission never overrides a properly better pick.
1. Bosch 750W Corded Angle Grinder – Best All-Rounder
Amazon’s Choice on this search isn’t a random algorithm pick – 74 reviews at 4.7 out of 5 for a corded grinder at this price is a genuinely strong result. 750 watts and a 125mm disc puts it squarely in the sweet spot for cutting steel angle, grinding welds smooth and trimming pavers, without the bulk of a trade-grade 1200W-plus machine.
Corded means no battery to charge or run flat mid-job, which matters for anyone doing a long weekend of fence repairs or metalwork rather than the odd five-minute cut. The trade-off against the cordless picks below is obvious the moment you need to work somewhere without a power point nearby – up a ladder, out past the shed, or anywhere an extension lead becomes its own hazard.
- Pros: Strong review base for the price, never runs out of charge, enough power for most home workshop and repair jobs
- Cons: Cord limits reach compared with the cordless picks below; 125mm disc size caps how deep a single pass can cut
Key specs: 750W motor, 125mm disc, corded electric
CHECK ON AMAZON2. Makita 18V Brushless Angle Grinder – Best Premium Cordless
Over 7,000 ratings at 4.7 out of 5 is an enormous sample for a single tool, and it reflects how deeply embedded Makita’s 18V LXT battery platform already is on Australian job sites. Buy this grinder and it slots straight into a battery collection that likely already includes a Makita drill, impact driver or circular saw sitting in the same ute toolbox.
This is a “skin only” listing – the tool body without a battery or charger – which is standard practice for a brand-loyal buyer topping up their kit, but it’s a genuine trap for a first-time buyer expecting a ready-to-use grinder in the box. Check you actually own compatible 18V LXT batteries before adding this to the cart, or budget for a battery and charger on top of the listed price. The brushless motor runs cooler and lasts longer than a brushed equivalent, and the slide switch design is a small but real safety detail over a simple trigger.
- Pros: Enormous, well-established review base, shares batteries with the rest of a Makita 18V tool collection, brushless motor for longer runtime per charge
- Cons: Skin only – no battery or charger included, easy to miss if you’re new to the brand; the priciest tool body in this guide before you even add a battery
Key specs: 18V LXT brushless, 125mm disc, tool body only (battery not included)
CHECK ON AMAZON3. DongCheng 20V Cordless Angle Grinder Kit – Best Value Cordless Kit
Unlike the Makita skin above, this one arrives as a complete kit – grinder, a 4.0Ah battery, charger and a carry case, ready to cut the moment it’s charged. For someone starting a cordless tool collection from scratch instead of adding to an existing one, that changes the real cost picture significantly once you account for what a separate battery and charger would add to a bare tool.
Only 7 ratings so far is a genuinely small sample – treat the 4.7 average as an early, promising sign, not a settled track record the way Makita’s 7,000-plus reviews represent. Anti-kickback and drop protection are worth calling out specifically, since a lower-cost cordless grinder skipping these safety features is exactly where corners tend to get cut. At 1000W and up to 9000RPM across three speeds, the spec sheet reads closer to the corded options above than a typical entry-level cordless tool.
- Pros: Complete kit with battery, charger and case included, anti-kickback and drop protection built in, strong power spec for a cordless tool
- Cons: Very small review sample so far; a less established brand name than Bosch or Makita for anyone buying on reputation alone
Key specs: 20V brushless, 125mm disc, 4.0Ah battery and case included
CHECK ON AMAZON4. Bosch 620W Corded Angle Grinder – Best Budget Corded
This is the cheapest way into a proper Bosch grinder in this entire guide, and 139 reviews at 4.5 out of 5 shows it’s earned its Best Seller badge honestly, not through low pricing alone. A smaller 100mm disc and 620 watts trades some raw capability against the 750W pick above, in exchange for a lighter, easier-to-control tool for anyone whose jobs skew toward smaller cuts and general maintenance instead of heavy fabrication.
It comes with a grinding disc in the box, a small but real saving over a bare tool that leaves the first disc up to you to sort out. For a renter doing the odd repair job, or a first grinder for someone who’s never owned one, the smaller disc size is arguably the safer starting point – less torque to control, less kickback force if a disc catches.
- Pros: Real Bosch reliability at the lowest price on this list, includes a grinding disc in the box, lighter and easier to control than the larger models
- Cons: Smaller 100mm disc limits cutting depth on thicker material; less headroom for heavy or continuous fabrication work
Key specs: 620W motor, 100mm disc, corded electric, disc included
CHECK ON AMAZON5. TOPEX 1200W Heavy-Duty Angle Grinder – Best Heavy-Duty Motor
1200 watts is a real step up in raw power from every other corded grinder on this list, more than half again what the Bosch all-rounder above puts out. A magnesium gear housing sheds heat faster than the plastic housings on cheaper grinders, useful if you’re running the tool for stretches longer than a quick weekend job, and the auxiliary handle bolts onto either side for left or right-handed control.
21 ratings at 4.1 out of 5 is a smaller and slightly more mixed sample than the Bosch or Makita entries above, worth knowing before you buy on power spec alone. More torque also means more force to control if a disc binds, so this suits someone who already has grinder experience over an absolute first-timer reaching for their first tool.
- Pros: Highest wattage corded motor here, magnesium gear housing for better heat handling, adjustable auxiliary handle for either hand
- Cons: Smaller, more mixed review sample than the established brands above; more raw torque to control than a beginner may want as a first grinder
Key specs: 1200W motor, 125mm disc, corded electric, auxiliary handle
CHECK ON AMAZON6. TOBAIL 18V Brushless Angle Grinder – Best Budget Cordless
Same trick as the Makita above – a tool body built to run on existing 18V LXT-compatible batteries – but at roughly a quarter of the price of the genuine article. If you’re already holding a drawer of Makita batteries from other cordless tools, this is the cheapest way to add grinding to that same battery collection without paying Makita’s own premium for the badge.
Only 12 ratings and stock that’s been running thin at times means this is the biggest unknown quantity in the entire guide – a reasonable bet for a backup or occasional-use grinder, not the one tool you’d want to rely on for daily trade work. Four speed settings give more control over material than a single-speed budget tool typically offers.
- Pros: Works with existing Makita-compatible 18V batteries, four speed settings, the cheapest cordless option in this guide
- Cons: Very small review sample and stock has run low at times; an unproven brand next to Makita, Bosch or DongCheng
Key specs: 18V brushless, 125mm disc, 4 speed settings, Makita-compatible battery interface
CHECK ON AMAZONHow to Choose an Angle Grinder in Australia
Match disc size to the job, not the other way around. A 100-125mm grinder covers nearly everything a home workshop or trade repair job needs – fence repairs, welding clean-up, tile and paver cutting. Only step up to a larger disc size if you’re regularly cutting through thicker steel or masonry than these six models are built for.
Corded versus cordless comes down to where you actually work. A home workshop with a power point nearby suits a corded grinder just fine, and you’ll never fight a flat battery mid-cut. Working up a ladder, along a fence line, or anywhere a trailing cord becomes its own trip hazard is where cordless earns its higher price.
Check if you’re buying a tool body or a complete kit. Skin-only listings like the Makita above assume you already own compatible batteries and a charger from the same brand’s tool range. A first cordless tool almost always makes more sense as a complete kit, even at a lower headline power spec, once the cost of a separate battery and charger is added to a bare tool body.
Safety features are not optional extras on a tool this powerful. Anti-kickback protection, a slide or paddle switch that won’t restart on its own after a power cut, and a properly fitted guard all matter more on an angle grinder than on almost any other handheld power tool – a disc that binds and kicks back happens in a fraction of a second, faster than a hand can react. Always wear safety glasses and hearing protection, and check for AS/NZS-compliant discs rated for the RPM your grinder actually runs at.
Buy discs to suit the job before you need them. A cutting disc, a grinding disc and a flap sanding disc all do different jobs on the same grinder body, and turning up to a job with only one disc type on hand is a common first-timer mistake. Stock a small range once you know which jobs you’ll actually be doing.
You’ll Also Want
Safety glasses rated for impact protection are non-negotiable with any grinder throwing sparks and metal fragments at speed – a cheap pair costs less than a single cutting disc and does a job no amount of experience replaces.
A spare pack of cutting and grinding discs in the sizes your grinder actually uses means a worn-out disc mid-job doesn’t turn into a trip to the shops, and buying a multipack up front works out cheaper per disc than buying single replacements as needed.

Frequently Asked Questions
What size angle grinder do I need for home use?
A 100mm or 125mm disc angle grinder covers nearly all home workshop needs, including cutting steel angle, grinding welds, trimming pavers and general repair work. Larger disc sizes belong to heavier fabrication and trade work most homeowners never need. If you’re only buying one grinder, 125mm gives slightly more cutting depth than 100mm for a small step up in weight and price.
Is a cordless or corded angle grinder better?
Corded grinders run continuously without ever needing a recharge, making them the better choice for a home workshop near a power point. Cordless grinders trade that endless runtime for freedom to work anywhere a cord can’t safely reach, such as up a ladder or along a fence line, and increasingly share batteries with a brand’s wider cordless tool range. Neither is objectively better – the right choice depends on where the tool actually gets used.
What does skin only mean on an angle grinder listing?
Skin only means the listing includes just the tool body, with no battery or charger included. It’s standard for buyers already holding compatible batteries from other tools in the same cordless range, letting them add a new tool without paying for a battery and charger they don’t need. First-time buyers should check compatible batteries are already owned, or budget for them separately before buying a skin-only listing.
How do I stop an angle grinder from kicking back?
Kickback happens when a spinning disc binds in the material and the tool suddenly twists back toward the user. Always hold the grinder with both hands using the auxiliary handle, keep the guard properly fitted rather than removed, let the disc reach full speed before contacting the material, and never force the cut faster than the disc can handle. Grinders with built-in anti-kickback protection cut power automatically the instant binding is detected.
What safety gear do I need to use an angle grinder?
Impact-rated safety glasses are essential every time the tool is running, since sparks and metal fragments travel fast and land close to the operator’s face. Hearing protection matters over extended use, and gloves improve grip while protecting hands from heat and sharp edges on freshly cut metal. A dust mask is worth adding for masonry and tile cutting, which throws fine particulate the lungs don’t need.
Can one angle grinder cut metal, tile and stone?
Yes, provided the correct disc is fitted for each material – a metal cutting disc, a diamond blade for tile and stone, and a grinding or flap disc for smoothing welds all suit the same grinder body. Never use a metal-rated disc on masonry or vice versa, since discs are rated for specific materials and speeds for safety reasons. Keeping two or three disc types on hand covers most home workshop jobs without needing a second tool.
Verdict
The Bosch 750W Corded Angle Grinder is the pick for most Australian buyers – proven, affordable and ready to run the moment it’s plugged in. Anyone already invested in Makita’s 18V battery platform should go straight to the Makita cordless pick above, and a first-time cordless buyer with no existing batteries gets better value from the DongCheng kit than from adding a bare tool body and battery separately. Whichever one comes home, budget for a proper set of discs and safety glasses before the first cut, not after.
