Motor and Speed

The Hitachi G12SR4 comes with a powerful motor that can produce 980 watts of power. This makes it strong enough for heavy-duty grinding jobs.

It also allows you to work on several types of materials and finish different metals, including aluminum, bronze, and even steel.

Not only that, but the Hitachi G12SR4 can also grind slate, brick, marble, and synthetic resin. It’s one of the best options for grinding welded selections.

The Bosch 1375, on the other hand, comes with a very powerful 6 amp motor that enables it to work at speeds up to 11,000 RPM. It’s a very great option if you’re looking for something to finish very heavy-duty tasks and professional-grade projects.

And although it’s small, it can tackle materials as hard as masonry thanks to its dry diamond cutting wheel. You can use it to cut tile, stone, brick, and more.


The Hitachi G12SR4’s impressive power provides it with versatility and an ability to remove casting fin, grind welding selections, and much more.

This is because its spindle lock facilitates the changing process of discs and other accessories.

And while the Hitachi G12SR4 doesn’t come with a wide variety of accessories, it’s compatible with many, including wire brush attachments. Just make sure you follow the instructions before using accessories that you buy separately.

On the other hand, the Bosch 1375 comes with a dual-position side handle that’s positioned naturally and conveniently to provide the user with the best control over their tool.

Its 5/8-inch to 11-inch adjustable spindle allows you to work with various popular accessories and attachments as well as change the wheels quickly and seamlessly.

Both the Hitachi G12SR4 and Bosch 1375 are equipped with a trigger that locks the tool on for continuous operation –this makes them more convenient than having to keep pressing down the button.

If you love working with no breaks or interruptions, either model will suit you very well.


The Hitachi G12SR4 comes with five abrasive wheels, so you’ll have access to good quality grinding wheels whenever they’re required. This variety is superior to most angle grinders that come with only one or two abrasive wheels.

The Bosch works with low vibration to give you the most stable performance. It’s both compact and versatile yet very powerful and reliable.

It also comes with an excellent warranty option that guarantees the durability of the unit.

Which is Better the Hitachi G12SR4 or Bosch 1375?

Both the Hitachi G12SR4 & Bosch 1375 are very good choices if you’re looking for a reliable angle grinder. But the slight difference in performance and features will help you choose the one that suits your needs better.

If you’re looking for a more powerful tool that works with higher accuracy and strength, I’d recommend going for the Bosch 1375.

However, if you’re looking for something more versatile that could work for DIY and professional jobs alike, opt for the Hitachi G12SR4.
