About FLEX manuals on Manuals.plus

FLEX is a renowned manufacturer of professional-grade power tools, originally established in Germany in 1922. The brand is historically significant for inventing the world's first high-speed angle grinder in 1954, a tool so iconic that "flexing" became a common term for grinding in many parts of the world. Today, FLEX specializes in heavy-duty tools for metalworking, stone finishing, automotive polishing, and drywall construction (famously known for the FLEX Giraffe® sander).

In addition to its traditional corded lineup, FLEX has introduced the advanced FLEX 24V cordless platform, featuring Stacked Lithium battery technology for superior power and runtime. The product range includes angle grinders, polishers, impact drivers, hammer drills, and dust extraction systems, all engineered to meet the rigorous demands of professional tradespeople.
