Our take on the Bosch 4-1/2" Wheel Diam, 11,000 RPM, Corded Angle & Disc Grinder
The Bosch GWS9-45 is a corded 4-1/2 inch angle grinder with an 8.8 amp motor that spins wheels at up to 11,000 RPM. It uses the common 5/8-11 spindle, so standard grinding and cutting wheels and wire cups fit directly. It is a compact, one-hand-class tool aimed at metalwork, weld cleanup and light masonry jobs. Against 4-1/2 inch grinders with smaller motors, it trades a little weight for more cutting power; against larger 5 and 6 inch grinders it is lighter and easier to control but limited to smaller wheels.
- 8.8 amp motor gives strong torque for a 4-1/2 inch grinder
- 11,000 RPM top speed suits thin cutting wheels
- Standard 5/8-11 spindle takes common accessories
- Runs on ordinary 120 volt household or jobsite power
- Compact body for one-handed work in tight spots
- Corded, so it needs an outlet or extension cord
- No battery option for remote work
- 4-1/2 inch wheel size limits depth of cut versus 5 or 6 inch models
- Grinding dust and sparks require eye and face protection

Questions and answers
- What wheels fit the Bosch GWS9-45?
- Any 4-1/2 inch wheel with a 5/8-11 threaded arbor, including grinding discs, cutting wheels, flap discs and wire cups. The 11,000 RPM rating means wheels must be rated at least that fast.
- Is 8.8 amps enough for cutting steel?
- Yes for most shop and jobsite work. It cuts sheet metal, rebar and bolts steadily; very thick stock or long continuous cuts will slow it and are better handled by a larger grinder.
- Does it need a special outlet?
- No. It runs on standard 120 volt power, so a normal wall outlet or a heavy-duty extension cord works. Use a cord rated for the tool's current draw.
- How does it compare with a 5 inch grinder?
- It is lighter and easier to control but cuts less deep. A 5 inch grinder takes larger wheels and clears more material per pass, at the cost of weight and bulk.
- Is it a one-hand tool?
- The compact body allows one-handed use for light work, but two hands on the body and side handle give better control for cutting and heavy grinding.
- What is in the box?
- The grinder itself with its side handle and wheel guard. Wheels and discs are usually sold separately, so check what the listing includes before buying.
