The 7 Best Angle Grinders of 2026

Let go of the paddle and the wheel stops in about two seconds instead of winding down on its own. That sounds like a small thing until you're up a ladder or lying under a trailer, where it decides whether you can set the tool down or have to keep holding it away from everything.

The rest of the safety package is just as deliberate. A two-stage trigger needs two separate actions before the wheel turns, so a glove catching on the paddle doesn't start the tool, and the kickback brake cuts in when the wheel pinches, stalls, or binds. We noticed it most on sheet metal, where a cutoff wheel likes to grab.

The brushless motor and 3.8-pound body give you the work of a small corded grinder without a cord dragging through the barn aisle. The runtime story depends entirely on which pack you clip on: the compact batteries that come with a drill kit won't carry you through a long session, while a large 20V MAX pack turns it into a genuinely useful tool.

For our money this is the cordless grinder of the group. The brake and the two-stage trigger are what we notice every single time we pick it up, and they are the difference between a tool that feels controlled and one that just spins a disc.

Set this next to our top pick and the trade is easy to see: no case, no set of wheels, but a 7.5-amp motor spinning 12,000 rpm and a low-profile jam-pot gear case that slips into places the Makita's rounder head won't go.

That gear case is the reason to pick it. Cleaning welds inside a trailer frame, or dropping a cutoff wheel between the pickets of a gate, you feel the smaller head immediately — you reach the joint instead of grinding the metal beside it. The one-touch guard turns by hand and the quick-change release lets you swap wheels without hunting for a wrench, which matters when you're trading a cutoff disc for a flap disc every few minutes.

The paddle is a hold-to-run switch, and we count that as a feature for overhead or one-handed work: let go and it stops. The trade is your hand during long grinding sessions, where a lock-on switch like the Makita's is kinder — for short jobs in tight steel, it's the switch we prefer.

Nothing else here gets you cutting for less. The Metabo HPT arrives with five grinding wheels and a hard case, and its 6.2-amp motor turns 12,000 rpm — the kind of numbers we expect to see on a tool priced a good deal higher.

For sharpening blades, dressing a gate hinge, cutting rusted bolts off a cinderblock wall, or slicing a length of pipe, it has plenty of torque and it steers easily. The side handle cants forward and unscrews so a left-handed user isn't fighting the tool, the spindle lock makes wheel changes quick, and the case keeps the whole thing together in the truck bed instead of rolling around loose.

The left-mounted slide switch is the flaw. It's small, your thumb has to hunt for it, and with work gloves on you'll fumble the shutoff — a real annoyance on a tool you sometimes want to stop in a hurry. It's manageable once you know to press the leading edge to lock it on, but it's the thing that keeps this out of the top spot.

This is the cordless grinder to buy if the red packs are already on your shelf, and the wrong buy if they aren't. What you get is a bare tool that runs 4-1/2-inch and 5-inch wheels on a 5/8-inch-11 spindle, so one grinder covers a cutoff disc for rebar and a flap disc for a rusted gate frame.

The safety electronics are the part we point to: an electronic clutch that cuts power when the wheel binds, overload protection that shuts the motor down before it cooks, and an anti-vibration side handle we were glad of during a long stretch of grinding welds. The spindle takes the common accessories, so the discs you already own will fit.

Where a cordless grinder gives ground is runtime, and this one is no exception: a compact pack empties fast under load, so pair it with the largest M18 battery you own and keep a second one charged. If the M18 packs aren't already yours, the appeal drops away — a corded kit does more work in a day for less money.

Half an inch of wheel doesn't sound like much until you're cutting 2-inch angle iron or a section of pipe that a 4-1/2-inch disc won't reach through in a single pass. This Makita takes both sizes, and it ships with a 5-inch cut-off wheel, an INOX grinding wheel, and both guards.

The brushless motor is electronically managed, changing speed and torque as the load changes, and the safety feature we care about most is AFT, which shuts the motor down if the wheel is suddenly forced to stop. Bind a cutoff wheel in a cut and the tool quits instead of kicking back at you. At 8,500 rpm it is slower than the corded grinders here, and that shows up in heavy stock removal.

So we treat it as a specialist rather than a first grinder: the one for someone already on 18V LXT batteries who wants 5-inch capacity without a cord. A small pack gets you through a handful of cuts; a long session means swapping batteries, and thick steel takes longer than it would with an 11,000 rpm corded tool.

Eighteen volts, a brushed motor, and 9,000 rpm: this is the oldest recipe in cordless tools, and the grinder follows it closely. There's no battery or charger in the box, just the tool and whatever pack you already own.

The case for it is your battery shelf. If One+ packs are already in the shop, this is the cheapest way to keep a grinder in the truck for jobs that don't justify dragging out an extension cord — sharpening a mower blade, shortening a bolt, punching through a hinge pin. It's easy to handle one-handed for that kind of work, and it takes the same packs as everything else you own.

We treat it as a convenience tool rather than a workhorse. For a handful of cuts it is genuinely handy and the entry price is low if the batteries exist, but a brushed 18-volt motor is where this class of tool stops, and a long stretch of grinding or cutting is asking it to do a job it wasn't built for. Anyone planning real steel work should be looking at the corded picks here instead.
