Bosch Professional GWS 9-115 S 900W Corded Angle Grinder (110V) with Auxiliary Handle

The essentials

Bosch Professional’s GWS 9-115 S is a corded angle grinder aimed at steady, practical work where you want progress without constantly swapping tools or waiting around. It’s built around a 900W motor, and Bosch leans into a slim, ergonomic grip so the tool sits comfortably in the hand during cut-off and grinding sessions.

On paper, it suits the kind of jobs tradespeople and competent DIYers do regularly: shaping metalwork, tackling rust or weld prep, and powering through abrasive tasks using the right accessories. The “S” in the name hints at a straightforward, no-nonsense approach rather than a gimmick-heavy feature set.

What you’ll notice in use

The biggest day-to-day difference here is how controllable the grinder feels, thanks to the thin grip and ergonomic design. Angle grinders can get fatiguing if the body doesn’t suit your hold, so a comfortable hand position really matters once you’ve been at the bench for a while.

Bosch also mentions a speed selection approach for matching outcomes to different materials and accessories. That’s a sensible feature because not every job benefits from the same speed—some setups prefer a gentler touch to avoid grabbing or uneven finishes.

A small practical example: if you’re prepping a metal edge before fitting, you typically start at a more controlled setting, take down the high spots with an abrasive accessory, then switch approach as the surface evens out. With a corded grinder like this, the main limitation becomes your access to power rather than battery runtime.

Key features that matter (and where they help)

Where this model makes sense is in predictable, repeatable workshop work. A corded angle grinder can feel “always ready”, and that matters when you’re doing a run of similar cuts or grinds.

• 900W motor for fast work progress: useful when you want momentum, not just gentle, slow removal.
• Slim grip and ergonomic design: helps maintain control for longer sessions.
• Speed selection for matching materials/accessories: handy when you switch tasks or use different attachments.
• Includes an auxiliary handle: improves stability compared to using only the main grip, especially on heavier control moves.

It’s not perfect, of course. If your work area is awkward or you often need full freedom away from mains power, a corded unit can feel restrictive—so you’d want to plan cable reach.

Who it suits (and who should skip it)

It’s a solid pick if you want a mainstream corded angle grinder for frequent workshop tasks and you care about control during use. The slim ergonomic hold and included auxiliary handle point towards a tool that’s meant to be handled confidently, not just powered on.

It may not suit you if your priority is maximum portability or you often work where mains access isn’t practical. Also, if you’re the sort of buyer who expects lots of advanced, job-specific features beyond basic speed selection, this looks more like a practical workhorse than a “premium all-rounder”.

Worth considering if you’re choosing between approaches: a corded grinder like this is often the go-to when you value consistent power, while battery options can be more convenient if you’re working off-grid.

Is it worth it?

Bosch Professional GWS 9-115 S is worth a look if you want a corded angle grinder with a 900W motor, an ergonomic thin grip for better control, and speed selection to adapt to different materials and accessories. For many real-world jobs, that combination is exactly what you reach for—particularly when you’re doing repeatable grinding or cutting tasks.

You might want to avoid it if you routinely work in places without reliable mains power, because the cable becomes part of the job. And if you’re expecting information that goes beyond what’s listed here—like specific disc sizes, no-load speed, or extra safety/feature systems—you’ll need to check the full listing details before committing.
