The QEP 21700 is a high-performance, 1,400-Watt variable speed electric power mixer designed for professional tile installers and serious DIYers. It efficiently handles thick, viscous materials like thinset, mortar, grout, and cement. The mixer features a 0–800 RPM variable speed dial and a 2-speed gearbox (low: 0–480 RPM, high: 0–800 RPM) for precise control, reducing splashing and ensuring a smooth, consistent mix. It includes the QEP 21661 mixing paddle (24 in. long with a 5-1/2 in. wide blade) and a 1/2 in. chuck kit, allowing compatibility with both M14 threaded and non-threaded paddles. A convenient lock-on function lets you maintain your desired speed without holding the trigger, reducing hand fatigue. The unit has a durable, cast aluminum gearbox, double-insulated motor for splash protection, and a co-molded handle with a non-slip rubber grip for comfort and control.
