Bosch Professional Angle Grinders cover cutting, grinding, deburring and surface preparation on metal, masonry and concrete. Tooled-Up.com stocks corded 240v models such as the GWS 12-125, GWS 14-125 S and GWS 20-230, alongside cordless 12v and 18v brushless grinders for work away from mains power.

Disc sizes run from the compact 76mm GWS 12-76 V-EC to 115mm and 125mm grinders, up to the 230mm GWS 20-230 for heavy-duty cutting. There is also a specialist tool, the GBR 18V-15 S cordless concrete grinder, built for dry grinding on mineral surfaces.

What sets these grinders apart is how closely each one is matched to a job, whether that is fine metalwork in tight spaces, all-day site grinding or cable-free surface smoothing.

Key Features of Bosch Professional Angle Grinders

• Brushless motors: Most cordless models, including the GWS 18V-7, GWS 18V-8 and GWS 18V-11 series, use brushless motors. These give more efficient power delivery and longer runtime per charge, with less motor wear.
• Variable speed: The GWS 18V-11 S offers variable speed, so you can match disc speed to the material, from slower polishing and finishing to full-speed cutting.
• Speed selection on the concrete grinder: The GBR 18V-15 S lets the operator set output for the substrate, whether concrete, stone, screed or marble.
• Cordless freedom: The 18v models suit site work, working at height and jobs where cable access is limited. The 12v GWS 12-76 V-EC is a lightweight option for detailed work.
• Corded consistency: The 240v GWS 12-125, GWS 14-125 S and GWS 20-230 suit workshop and long-duration use with no batteries to manage.

Frequently Asked Questions

Should I choose a corded or cordless Bosch Professional angle grinder?

Choose cordless 18v for site work, working at height or anywhere a cable is a nuisance. Choose a corded 240v model for continuous workshop use or when you need the 230mm disc size.

Which disc size is best?

115mm grinders offer the best control in tight spaces, and 125mm is the best all-rounder for general metalwork and construction. Go for 230mm when you need greater cutting capacity on heavy-duty jobs.

What does a brushless angle grinder offer?

Brushless motors run more efficiently, which helps battery runtime and reduces wear on motor parts. This makes them a sensible choice for regular professional use.

Can I cut concrete with these grinders?

With a suitable diamond disc, a standard grinder can cut masonry. For grinding and smoothing concrete, the GBR 18V-15 S is the purpose-built option. Always manage dust in line with COSHH guidance and wear suitable PPE.
