Intro
HiKOKI — the brand formerly known as Hitachi Power Tools — produces a range of 18-volt cordless tools that compete directly with the major manufacturers on features and build quality, often at a more accessible price. Their G18DSL2 is a 125 mm cordless angle grinder designed for the professional and serious DIY markets, offering restart protection, a spindle lock for easy disc changes, and a compact, lightweight body that aims to make cordless grinding and cutting as comfortable as possible over extended use.
Generalities
The G18DSL2W3Z is an 18-volt cordless 125 mm angle grinder in HiKOKI's MultiVolt platform. It spins discs at 9,000 RPM and includes restart protection — if power is interrupted, the tool will not restart until the switch is cycled off and on. With 28 customer reviews averaging 4.1 out of 5 stars, feedback is solid if not exceptional. Sold as a bare tool.
This review examines the grinder's power-to-weight ratio, the restart protection feature, and the value proposition for users already invested in HiKOKI's battery platform.
Description
The grinder drives 125 mm discs at 9,000 RPM, providing adequate cutting power for steel, rebar, bolts, masonry, and tile. The compact, lightweight body is designed for comfortable handling — HiKOKI has prioritised reducing weight and bulk to make the grinder manageable for one-handed use during light grinding and surface preparation, while still providing the two-handed control needed for cutting.
The spindle lock enables quick disc changes, and the restart protection prevents accidental startup if a battery is inserted while the switch is in the on position. The tool is compatible with HiKOKI's 18V and MultiVolt batteries. Customer feedback from 28 reviews averaging 4.1 out of 5 stars suggests the grinder performs well within its intended light to medium professional use — it is not a replacement for a heavy corded grinder, but it handles the quick cuts and grinding tasks that make up most of a working day.
