We tested the power of the collomix cordless mixer collomix XO10 battery powered mixing drill here.
As you can see the collomix cordless mixer is more than capable of mixing a batch of 85 KG of concrete and there was still power left in the battery to make another batch.
We used the Metabo 8 Amp battery for this and the KR mixing shaft which was a quick release.
As you can see the mix which was used for a footing for a concrete pillar was mixed quite stiff so it was impressive to see the cordless mixer work through this toughest of mixing jobs.
The Xo10 is supplied with a body only or a battery and body kit here at PFT Wales
The Collomix range of mixing paddles will cover any mixing job you have and being cordless it is extremely versatile.
