Diamond Blade Segmented for Brick Chasing 150mm x 22mm x 6mm Seg Cable Trenching


These diamond blades have 6mm wide segments for trenching in brick for electrical cable.


  • Rapid brick and mortar removal when trenching for electrical or plumbing applications.
  • Can be used for either wet or dry cutting. Extended blade life will be experienced with wet cutting.
  • Use when trenching or wall chasing in clay brick.
  • Diamond blades do not cut, they actually grind through the material by exposing new diamond at the right moment just before the old diamond wears away.
  • The newly exposed diamonds again will wear, chip, or break out of the metal bond in the segment, while the metal bond gradually wears away to expose new diamond. This process is repeated over and over until there is no diamond remaining and the blade is worn out.
  • Ideally and to get the maximum life out of a diamond blade, the metal should wear away at just the right time to expose new diamond for optimum cutting performance.
  • If the metal wears away too quickly, the diamonds are exposed to soon and get torn out of the metal bond before they are fully worn. The result is a very short blade life.
  • If the metal wears away too slowly, the diamonds wear away before new diamond is exposed. This is often referred to as a 'glazed blade'. Without exposed diamond the blade will not cut.
  • Abrasive materials like green concrete and asphalt will wear the metal bond very fast, so blades for these materials have a much harder metal bond to resist this abrasion.
  • The opposite occurs on a hard clay paver the clay paver is not abrasive enough to wear the metal bond fast enough to expose fresh diamond, therefore a different and much softer alloy is needed for cutting these types.
  • The single most important factor for the life of the blade is to match it to the job application and the type of equipment it is being used on.
