This range of mortar mixer paddles have a M14 x 2 thread connection which is directly adaptable to all Rubimix mortar mixers and most other brands. The mixer paddles for adventitious mortars have a head designed to perform a movement from the bottom up. The mixer paddle 3H has a propeller-head with 3 paddles for greater mixing efficiency. This design increases performance compared to the 2-paddles propeller-head. In addition, the 3H reduces the stress of the mixer while working, which means greater durability. The 3-paddles propeller-head generates less vibration, so the user can work with a higher level of comfort.
