Best Cordless Angle Grinders in 2027

The DEWALT DCG413B leads our Best Score at 78. At 3.75 lb it is one of the lightest 4-1/2 in grinders on this page, which makes a real difference when grinding overhead or holding the tool at an angle for long periods.

Its safety features stand out. A Kickback Brake engages when a pinch, stall or bind-up is sensed and stops the wheel quickly, and the regular brake stops the wheel in 2 seconds or less on average. E-Switch Protection means the trigger will not restart the tool on its own after a power interruption.

The brushless motor needs no brush changes and runs up to 9000 rpm with a 4.5 in disc. It is sold as a bare tool, so you need a DEWALT 20V MAX battery and charger. For anyone already on DEWALT batteries, it is the safest and most comfortable cordless grinder here.

Second with a Best Score of 74, the Milwaukee 2880-20 is the M18 FUEL grinder for 4-1/2 in or 5 in wheels. An electronic clutch provides kickback protection by reacting when the wheel binds, and overload protection helps maximize motor life.

The brushless motor and FUEL electronics are built for demanding cutting and grinding. An anti-vibration side handle reduces hand fatigue and improves control during long sessions. It works with all M18 batteries, so Milwaukee owners can add it as a bare tool.

At 4.99 lb it is heavier than the DEWALT DCG413B, and it is sold without a battery or charger. Its no-load speed is not listed in our data. For crews and shops on the M18 platform, it is the natural choice and matches the DEWALT for safety features. Pair it with a high-output M18 pack for heavy grinding, since grinders drain small batteries quickly.

The TEENO 3 in brushless grinder ranks third with a Best Score of 63. It is a smaller tool than the others, with a 3 in disc and a 500W brushless motor running on 16.8V. Its top speed is listed at 19500 rpm, the highest on this page, which suits small cut-off wheels.

The short gear head shifts weight back toward your hand, which makes one-handed cuts easier in tight spaces like exhaust work, rebar and tile edges. A smart LED display shows battery status. A 90 degree adjustable base guard deflects sparks away from your body as part of a dual-guard system.

Unlike the DEWALT and Milwaukee, it comes as a full kit: 2 batteries, a charger, 6 discs for metal cutting and other jobs, and a hard case. The 3 in disc limits cutting depth, so it complements rather than replaces a full-size grinder.

Fourth with a Best Score of 59, the DEWALT DCG410B belongs to DEWALT's most powerful line of 20V MAX angle grinders. Its brushless motor delivers up to 1,590 MWO and up to 9,000 RPM, built for heavy grinding and cutting.

An anti-rotation system senses excessive rotational motion of the tool and shuts it down, which helps control the grinder if the wheel snags. It is TOOL CONNECT Chip ready, with the chip sold separately, so crews can track it with the Site Manager app.

At 4.59 lb it is heavier than the DCG413B at the top of this page, and a kickback brake is not listed in our data. It is a bare tool, so add a DEWALT 20V MAX battery, ideally a larger pack for heavy work. For users who need more power than the DCG413B, it is a strong step up, especially for long cuts in thick steel or heavy weld grinding.

The DEKOPRO 20V cordless grinder completes our top five with a Best Score of 55. At 3.3 lb it is the lightest grinder on this page that lists a weight, and it arrives ready to work with 2 × 20V 4.0Ah batteries and a charger.

Its brushless motor gives longer motor life and better heat dissipation than brushed designs. It includes two wheel guards, a standard guard and a half-cover guard, to block sparks and debris in different jobs. A spindle lock makes wheel changes quick, and the 7/8 in arbor fits common 4-1/2 in wheels.

A side handle helps control. Speed and kickback protection are not listed in our data, so take extra care with cut-off wheels. For homeowners who want a complete cordless grinder kit without buying into a big-brand platform, it offers a lot in the box.
