Bosch Professional GWS 9-115 S corded angle grinder (900W) with auxiliary handle
Product description
What it is and why you’d buy it
The Bosch Professional Corded Angle Grinder GWS 9-115 S is a mains-powered, 900W small angle grinder aimed at day-to-day workshop jobs where speed and control both matter. On paper it’s built around a strong motor, a speed selection feature, and an ergonomic design with a small grip size—so it’s the kind of tool people reach for when they want fast progress without wrestling the tool into position.
If you’re doing things like cutting, grinding, or general surface prep across different materials, the speed control is the standout idea here. It’s not trying to be a heavy-duty “one tool for everything forever” machine, but it looks well pitched for regular DIY/handyman use and professional touch-up work where the cable power is simply part of the deal.
There’s one limitation to keep in mind: because it’s corded, your range is ultimately defined by your lead and your workspace. In a garage it’s fine, on bigger outdoor sites or awkward access areas, it can get inconvenient.
The essentials you’ll notice in use

Speed selection and ergonomics are the two things you tend to feel quickly. The GWS 9-115 S is described as offering fast work progress thanks to its 900W motor. That’s exactly what you want when you’re not interested in slow “creep along” grinding.
At the same time, the small grip size and ergonomic design are there to help with tool control. Realistically, that makes a difference when you’re switching angles often—think of trimming an edge, cleaning welds, or levelling a surface where you don’t want to fight the tool.
A practical way to picture it: imagine you’re smoothing a metal edge after a rough cut. With speed selection, you can dial things in rather than using a single fixed speed for everything. And with the auxiliary handle included, you’re not relying on one-handed balance for comfort and steadier handling.


Where it shines (and what “good” looks like)
This model is positioned as a small, corded angle grinder for producing working results across a variety of materials. The combination of:

- a strong 900W motor,
- speed selection,
- and a control-focused grip/ergonomic layout
…is the recipe it uses to hit “fast progress” while staying manageable in the hand.
It also comes with useful items in the box for getting set up quickly rather than having to hunt for basics.
What’s in the box
The scope of supply includes: backing flange, cardboard box, protective guard, locking nut, auxiliary handle, and two-hole spanners. That’s handy because it covers the early setup steps you’d expect with an angle grinder (guard and mounting hardware), without forcing you to improvise.

Is it the right fit for you?

It’s a good fit if you want a corded small angle grinder with speed selection for work across different materials, and you value tool control through a compact grip and ergonomics.
It makes sense if you’re doing regular grinding and prep tasks and you’d rather pay for a sensible feature set (motor strength + speed control + auxiliary handle) than compromise on handling.
You may want to skip it if your projects often involve limited access to power outdoors or you regularly work far from sockets—corded tools can slow you down there.
Not the best choice if you’re expecting a fully featured, “next level” workshop grinder experience, because the details provided here focus more on everyday progress and control than on advanced specs.

Final verdict

If you’re looking for a corded angle grinder that prioritises fast progress (900W) and gives you speed selection for dealing with more than one material type, the Bosch Professional GWS 9-115 S is worth considering. The inclusion of the auxiliary handle, protective guard, and mounting hardware in the box suggests it’s designed to be ready to use without extra scavenging.
Just be realistic about the corded format: if your work is often on the move or far from power, you might want to factor in that trade-off before buying. And if you care about specific technical details like disc size or exact speed ranges, check those on the listing since they’re not included in the information provided.
