21V Brushless Cordless Angle Grinder 4.5"
Key points
- Rotating head reaches awkward angles
- Brushless motor with up to 7.5Ah runtime
- Cutting, grinding, polishing & rust removal
- Tool-free guard & spindle lock
- Shares the 21V Li-ion platform across the cordless range
- No extension cords - full cordless freedom for rooftop, duct & field work
- One tool covers cutting, grinding, polishing and rust removal - fewer tools to buy for metal and tile jobs
- Rotating-head access helps maintenance crews finish awkward edge and overhead work without repositioning the workpiece
- Cordless multi-function operation helps field-service buyers cover cutting, grinding and polishing where outlets are unavailable
- The rotating head helps maintenance distributors support awkward-angle metalwork where a fixed grinder is harder to position
- Workshop benches can add a cordless grinder for quick deburring and weld dressing between jobs
- Tile and stone finishers can switch discs for cutting and edge dressing on the same tool, cutting down on the tools carried between rooms
- Fabricators can keep one grinder per bench and give each operator their own battery, cutting waiting time
- Tool hire shops can send the grinder out with one battery and discs, so a weekend DIY customer gets a complete cutting setup in a single hire line
- Weld dressing on a finished frame can be done in place, so a fabricated assembly does not travel back to the bench for one rough edge

Product detail
Versatile brushless cordless angle grinder with a rotating head for cutting, grinding, polishing and rust removal in hard-to-reach positions. The 21V brushless motor delivers consistent power with up to 7.5Ah battery capacity for extended working time. Features include tool-free guard adjustment, side handle for control and spindle lock for fast disc changes. Ideal for metalwork, construction, tile work and maintenance crews who need cordless freedom. The rotating head lets operators cut and grind flush against surfaces fixed-head grinders cannot reach, such as door frames, chassis rails and confined ductwork. Maintenance crews switch between grinding disc and polishing pad in seconds using the spindle lock, keeping changeover time to a minimum on the job. Because it shares the 21V battery platform, contractors already running the cordless range can add cutting and grinding coverage without buying into a separate battery system, and the tool-free guard and side handle keep setup quick on site. Contractors can order the grinder together with the cutting and grinding discs they use most, keeping consumable supply lined up with the tool so crews are not left waiting for a replacement wheel before the next metalwork job can start. Plumbing and heating crews can cut pipe and threaded rod on site where a bench vise is unavailable, so a repair in a plant room or service riser is finished during the same visit instead of being left for a return trip. Steel stockholders can cut bar and section to length at the trade counter on battery power, so a customer's order is prepared without walking the stock to a fixed saw. Cordless models increasingly set the standard for site mobility in 2026, because the cutting and grinding work can be finished where the work actually is instead of where the nearest power point happens to be. A grinder for a fabricator on a scaffold or a roof, where a lead would be a trip hazard and a socket is not within reach. Trade buyers now rank battery-powered angle grinders among the fastest-selling cordless lines, which is why this model is quoted as a complete kit for the shelf rather than a bare tool the buyer has to assemble from separate battery and accessory lines.
