Industries We Supply

DOT Diamond Tools supplies diamond blades, core bits, grinding wheels and cutting equipment to six sectors of the construction industry. Each one puts a different demand on the tooling — and buys differently as a result.

Who we supply, and why it matters

A blade that performs on a highway resurfacing job will disappoint on a bridge deck, and the tooling a plant maintenance crew keeps on the shelf looks nothing like what a tile contractor carries. The material is different, the machines are different, and the way the work is scheduled changes what “the right blade” even means.

These pages set out what each sector actually cuts, which bond and rim suit it, what fails when the specification is wrong, and the kit we would put on the truck. With 35 years in diamond tooling behind the recommendations, they are written to answer the question a buyer is really asking: what should I be running on this job?

Choose your sector

Highway ContractorsRoadway sawing, full-depth pavement repair and lane-closure work where abrasive asphalt and green concrete eat ordinary blades.Bridge ContractorsDeck sawing through heavy reinforcement, partial-depth removal, and anchor coring with runoff to control.Commercial ConstructionMixed-material cutting, service penetrations and fit-out work in occupied buildings where dust and fumes are the constraint.Utility ContractorsTrench cuts across live roadway, service penetrations through walls and vaults, and restoration that has to look right.MunicipalitiesPublic works crews covering everything from sidewalk repair to roadway patching on a fixed annual budget.Industrial ContractorsPlant maintenance inside short shutdown windows, hard cured slabs, equipment pads and surface repair.

What every sector gets wrong at least once

Bond hardness, backwards. Hard, dense, cured material takes a soft bond; soft, abrasive material takes a hard bond. It reads the wrong way round and it is the single most expensive mistake in the trade — see the bond guide.

Depth of cut. One pass should take no more than a third of the blade diameter. Choosing the cheaper, smaller blade is how a crew ends up making three passes where one would have done, which on a timed closure never pays.

Silica. Cutting and grinding concrete dry is one of the highest-exposure tasks on any site. Water at the blade or on-tool extraction is the practical route to compliance — see OSHA Table 1.
