Rubi M14 Threaded Mixing Paddles — Bottom-Up Blending, Less Strain The paddle does as much for your mix as the motor. These professional Rubi M14 paddles use a 3-blade propeller design that drives bottom-up blending, pulling unmixed material up off the bucket floor so you get a uniform batch with fewer dry pockets and lumps. A standard M14 x 2 thread fits the Rubimix mixers and most other M14 systems, so they drop onto the mixer you already run. They come in different diameters and lengths, so you can match the paddle to the mix volume and the material — a smaller head for a quick grout batch, a bigger one for a full bucket of thinset. The propeller geometry also reduces vibration and strain on both the mixer and the operator, which adds up over a day of mixing. Why Tile Pros Choose It Uniform mix: 3-blade propeller drives bottom-up blending with fewer dry pockets Universal thread: Standard M14 x 2 fits Rubimix and most M14 mixers Sized to the job: Multiple diameters and lengths for different mix volumes Easier on the tool: Reduces vibration and strain on mixer and operator For mortar to grout: Handles thinset, grout, and dense materials Pro durability: Built for repeated professional mixing Pro tip: Size the paddle to the bucket — too big and it bogs the motor and climbs out of the mud; too small and it won't turn the whole batch. Keep the paddle moving through the mix rather than parking it in one spot.
