All DURO diamond blades (except Duro Base) have a colour coded section on the label to match the material application type. Please ensure that your blade selection matches the material you intend to cut.
More than one colour code on a product label indicates that two or more applications are allowed with the blade.
White colour indicates highly dense and very hard materials such as granite, slate, Class A engineering bricks, clay products, flint concrete and heavily reinforced concrete.
Grey colour indicates universal use in most hard to medium hard materials such as reinforced concrete, Class B engineering bricks, kerbs, lintels, beams, cast pipes, flags and general building materials.
Yellow indicates that this product is designed to give the longest lifetimes with high in-feed rates in the widest possible range of construction materials, from the hardest engineering bricks and reinforced concretes to paviors, soft blocks.
Red indicates that this product is designed for cutting more or less anything on the construction site including, but not exclsively, various types of metal.
Pale blue indicates abrasive materials such as hand made bricks, facing bricks, concrete roof tiles, soft concrete paviors, green concrete, cement screed and other abrasive materials.
Black indicates extremely abrasive materials such as soft cemend screed, lightweight concrete and cellular block, abrasive sandstone and grit stone, as well as tarmac and hot rolled asphalt on roads and pavements.
The use of both grey and black indicates that this product is highly suited to both concrete and asphalt applications.
The use of four colour codes makes this specification our most universal. Cut almost any material, excluding heavy metal applications with absolute ease and security, whilst benefiting from very high lifetimes.
This is the application type of our DURO BASE entry line blades and this indicates that the blades are suitable for universal use in most medium to hard building materials, including lightly reinforced concrete, hard bricks, blocks and stones.
