About Bosch ADVANCEDGRIND 18V-80 P4A 18V Cordless Angle Grinder 125mm

The Bosch ADVANCEDGRIND 18V-80 P4A (product ID 100146189) is an 18V cordless angle grinder with a 125mm disc. It sits above basic DIY models and is built for more demanding home users who need performance without the bulk of a professional machine. It runs on the Bosch PowerForAll 18V battery platform so it works with any PowerForAll 18V tool you already own.

The variable speed dial runs from 2,800 to 12,000 RPM letting you match the speed to the job and the disc. The motor has a soft start so there's no sudden jerk when you pull the trigger. No battery is included this is a body-only tool and Bosch recommend a 4.0Ah battery or larger for best results.

The Quick Adjust guard rotates without tools and a separate cutting guard is included in the box. The anti-vibration side handle reduces fatigue and lets you press harder into the work. At just 1.7kg without battery the slim rear housing sits comfortably in the hand for extended use. It handles cutting and grinding across a range of materials.

Variable speed, tool-free disc changes via the Quick Change nut and PowerForAll battery compatibility make this a practical step up from entry-level grinders. The Syneon chip manages energy intelligently to get the most from your battery.

The Technology Explained

The ADVANCEDGRIND 18V-80 runs on Bosch's PowerForAll 18V lithium-ion platform. The standout feature is the electronic speed preselection dial which sets the no-load speed anywhere between 2,800 and 12,000 RPM far wider than most fixed-speed grinders at this level. The soft start motor ramps up gradually rather than hitting full speed instantly. A Syneon chip manages energy draw from the battery to extend runtime. The Quick Change nut removes the need for a spanner when swapping 125mm discs. At 1.7kg bare the slim rear housing keeps the tool manageable for longer sessions.

Using It Safely

Always fit the correct guard use the supplied cutting guard for cutting work and the grinding guard for grinding. Check that any disc you fit is rated to at least 12,000 RPM before use. Fit the anti-vibration side handle and grip it firmly throughout. Wear eye protection, gloves and hearing protection. The soft start reduces start-up jerk but wait for the disc to reach full speed before applying it to the work. Let the disc stop fully before setting the tool down.
