Our take on the Bosch Angle Grinder GWS10-450 4-1/2 Inch 10 Amp Ergonomic Corded Electric Cut-Off Tool

The Bosch GWS10-450 is a corded 4-1/2 inch angle grinder with a 10 amp motor spinning at 11,000 RPM. It weighs about 4.5 lbs and uses a slender barrel plus an anti-vibration side handle to cut hand fatigue during long grinding and cut-off work. Epoxy-protected field windings help it survive metal dust and masonry grit. It sits above budget 6 to 8 amp grinders on power and vibration control, while pro-grade 13 amp models offer more muscle for heavy continuous cutting.

About the Bosch Angle Grinder GWS10-450 4-1/2 Inch 10 Amp Ergonomic Corded Electric Cut-Off Tool

The Bosch GWS10-450 is a corded 4-1/2 inch angle grinder with a 10 amp motor and an 11,000 RPM no-load speed. It has a slim barrel body and weighs 4.5 lbs. It is used for grinding welds flush, beveling steel plate edges, deburring angle iron, scoring masonry joints, clearing mortar lines and cutting black iron pipe and rigid electrical conduit.

The motor has epoxy-coated field windings and double-sealed ball bearings to protect against stone fragments and metal filings. Internal airflow channels draw in air through rear openings and push debris away from the slide switch and motor windings. The Service Minder system automatically shuts off the brushes when they need replacing, which protects the commutator.

The multi-position side handle is anti-vibration and reduces strain on the joints. The tool-free adjustable guard rotates into several fixed positions to shield the user at different working angles.

Questions and answers

Is the Bosch GWS10-450 good for cutting steel?
Yes. The 10 amp motor and 11,000 RPM speed handle cut-off wheels on steel and rebar well. For long continuous cuts in thick stock, a 13 amp grinder holds speed better.
How does it compare with a 6 amp grinder?
It has noticeably more power and less bog-down under load. It also weighs more than small 6 amp models, so it is less ideal for light sanding and detail work.
Does it have a brake?
No. This model has no electronic brake, so the wheel coasts to a stop after you release the switch.
What size wheels does it take?
It uses 4-1/2 inch wheels with a 7/8 inch arbor, the common size for US angle grinders.
Is it safe for one-handed use?
The slim barrel and low weight make one-handed holding easier, but Bosch and safety guidance call for two hands with the side handle installed whenever possible.
What comes in the box?
The grinder, a side handle, a guard and a flange set. Wheels are usually sold separately.
