Extreme grinding and joint leveling with a Situp Grinder and Silver Turbo wheel illustrates how productive this combination can be.
Extreme grinding was required for our customer who had a factory to grind where all the slabs were uneven, mostly 25-30mm difference which required grinding down until they were level. He did not own three phase equipment and power on site was only 240V so he purchased a Situp Grinder.
After wearing out the Silver Turbo he purchased a couple of other expensive wheels for the job which ended up not being as productive or as smooth. Two more Silver Turbo wheels were purchased and the work began again.
14kg of weight was added to the Situp Grinder because the job required deep grinding into the aggregate and this made a big difference to the productivity.
The 178mm (7in) grinding wheel was the perfect size to apply a lot of force on the high edges to cut them down and then to smooth out the rest of the slab. The Situp attachment allowed the operator to lean down on the grinder as well until the grinder began to slow down. Working on this peak of performance intermittently the angle grinder could cope quite well.

A Husky 530 planetary grinder was used afterwards to wet grind the floor and finish the leveling.
