COLLOMIX Universal - Large Mixing Paddles - MKD Series Double Mud Mixer Drill Paddle Set for Concrete, Mortar, Epoxy and All Other Materials with HEXAFIX Connection - MKD140HF

Mixes as advertised, videos showing how it mixes help.

Works great if your mixing thick epoxy floor compound to prevent mixing in air bubbles. The alternatives I looked at all come with dual turbine blades which will create a pocket of air within the mixture. This is the only alternative.

First, as the description says, it does not fit in a half inch chuck drill. If you have a cheap 6" bench grinder this is easily remedied in about 5 minutes. I just rotated the shaft in my hand while using the coarse wheel and then finished off the job with the fine wheel. Since end of the shaft has six sides which are close to 1/2" it is easy to see whether your grinding is even as the points are ground off. When the points are gone you have a perfect circle of the right size. Before I touched things up with the fine wheel there was a slight wobble when run in my drill.I suppose that if you poured an entire 80 pound big of concrete in your bucket and then your water this thing might give a lesser powered drill some difficulty. I start by putting some water in the bucket and then adding the mix and then more water and more mix. This works very well, and this mixer is much easier on the bucket than the large diameter paddle that I was using previously.I am using a Ryobi One Brushless 1/2" drill with a 9aH 18v battery. It has plenty of power the way that I have been using it and has not been overheating. I have several mixing paddles, each of a different style, this one is the best in my opinion.

Official Collomix product. I had absolutely no issues using the paddle in the Collomix mixer and it does a great job. It also cleans easily in a bucket of water needing only a wipe down and a small brush for the nooks and crannies of the welds. The finish holds up very well so far, too. The price cannot be beat as opposed to buying retail.

Very heavy duty and worth the extra cost compared to cheaper made mixers. Mixes brick mortar in a five gallon bucket for repairs easily.

Mixing concrete in a 10 gallon bucket.

constructed well and very sturdy. I have been using it to mix concrete. Used it with my 1/2 drill, as I could not find a quality, affordable 1/2 paddle. If you go this route, you will need to sand/file down the end to get it down to 1/2 inch. Took me about 30 minutes with a hand sander.

Collomix makes the best mixing paddles in the industry
