Hitachi G12SR4 Angle Grinder Product Review

The Hitachi G12SR4 Angle Grinder is one of the most lightweight angle grinders we found, and if you’re looking for a home improvement tool, then this could be the one for you. It would work great for tile cutting, rust removal jobs, and even sharpening blades, as its lightweight design gives it a versatile feel. This also means it can be used for overhead operations without a struggle, so you can work in a variety of spaces with precise control and ease.

We would describe this grinder as a ‘medium-duty’ grinder. It includes a 6.2 amp motor, with a maximum power output of 980 watts. Despite being powerful, the grip perimeter is only 7-8 inches, so it’s comfortable for use over long periods.

If you’re wanting a tool that is durable and long-lasting, then you’ll be glad to know that this angle grinder comes with a carrying case, so you can store it away safely to prevent damage. It also features class-leading overload durability, which helps to increase the tool’s overall lifespan.

It features 5 abrasive depressed center grinding wheels, and a low diameter grip, which means you can feel comfortable holding the tool, even during extended use. Included with this grinder is a removable, forward canted side handle, so you can also comfortably gain better control over your tasks, whether you’re right or left-handed. The overall design helps to reduce hand fatigue, so you can be more productive for longer.

The Hitachi G12SR4 model comes with a trigger lock mechanism that allows for continuous, smooth operation, as well as a spindle lock, so you can easily change the disc and accessories. In addition to this, it also has a quick-off feature with a left-mounted slide switch, for enhanced safety.

The dimensions of the Hitachi G12SR4 is 10 x 4 x 4 inches, and, as it only weighs around 4 pounds, it is a lightweight tool that can be used to work in tight angles and compact spaces. If you have a task that demands precision, then this could be an excellent option for you to get your hands on.

While the overall control and operation of the tool is generally smooth, some customers have found that the on-off switch can be difficult to press whilst wearing gloves, so bear this in mind if you find this may be an issue for you.


If you’ve never used an angle grinder before, then you’ll be in for a treat once you start incorporating them into your construction and home improvement tasks. They increase efficiency and productivity, giving you powerful and high-quality results against tough materials.

With that in mind, the Hitachi G12SR4 Angle Grinder makes for a great overall tool, combining power with precision and lightweight portability. This is definitely an angle grinder worth considering if you’re looking to use the tool for DIY projects, too.
