A heavy-duty, factory-priced 125mm angle grinder built for global B2B buyers.
This 125mm Angle Grinder pairs a high-output brushless motor with a 125 mm (5 inch) disc platform and a powerful 21V lithium-ion battery system to deliver up to 8 000 RPM of cutting and grinding speed — strong enough to slice through steel rebar, thin pipe and sheet metal, and powerful enough for stone, tile and heavy rust removal. The brushless motor reduces friction, generates less heat and runs up to 50% longer per charge than comparable brushed models, which means lower service costs and higher end-user satisfaction for the angle grinder buyer in Southeast Asia, the Middle East, Central Asia and Latin America.
The 125mm Angle Grinder supports metal cutting, grinding, sanding and polishing by simply swapping discs — 1 mm cutting disc, 4 mm grinding disc, flap disc, diamond disc or wool polishing bonnet all fit the standard M14 spindle. A 3-position side handle, tool-free guard adjustment, spindle-lock button, electric brake and soft-start trigger make this angle grinder safe and versatile for daily commercial work. With a slim-grip housing, ergonomic anti-slip handle and dust-protected ventilation slots, it is built for jobsite durability. Custom logos, retail color boxes and private-mold services are available for brand owners looking to launch their own brushless angle grinder line.
