Rough Grinding
The first cutting stage on a floor: taking off laitance, coating residue and high spots to leave a flat, open surface. Every stage that follows is limited by how well this one was done. SES holds the range as an authorised Tyrolit distributor, covering grits Coarse strip grits; bonds Metal and hybrid, soft through hard; tooling Segments, PCD blocks, coarse cup wheels; passes Overlapping, cross pattern. Executions include coarse metal-bond segments, PCD stripping tools, hybrid first-cut segments, heavy-duty single segments, among others. It is specified most often into levelling trowel ridges on newly poured slabs and opening laitance ahead of a resin system. Every part is genuine Tyrolit through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Rough Grinding in the parts of a plant where this particular duty actually occurs. In practice that means levelling trowel ridges on newly poured slabs, opening laitance ahead of a resin system, stripping residual coating after PCD work, and equally grinding screed back to meet a level tolerance, first pass on a terrazzo restoration, preparing loading bay floors for heavy-duty coatings. What links them is the duty rather than the machine name — stage: First pass. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the Tyrolit range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Slab is out of level by several millimetres — Coarse grit on a heavy machine worked in a cross pattern. A light machine chases the surface up and down instead of cutting a datum. Surface needs to be open for adhesion rather than flat — One coarse pass, then stop and vacuum. Extra passes close the surface back up and undo the profile you just created. Reinforcement sitting close to the surface — Reduce depth of cut and map the area first. A coarse segment catching exposed rebar destroys the head along with the whole segment set. Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Grind the edges and corners at the same time as the main floor, not afterwards. Edge work done later never matches, and a visible border around a polished floor is a complaint you will hear about for years.
