Professional Series Diamond Blade with Segmented Rim for building materials. Standard 22.23mm bore size to fit all makes of hand-held angle grinders.

Segmented Rim blades give the roughest cut and is used for concrete, brick, concrete pavers, masonry/block, hard/reinforced concrete, and limestone. This blade is usually referred to as a dry-cutting blade.

It can be used on dry applications without water due to the segments (cutouts) on the edge of the blade. The segments allow for airflow and cooling of the blade core. The segments also allow for better “exhaust” of debris, allowing for a swifter cut.

One of the risks to the lifetime of a diamond blade is overheating, which affects the bond and can warp the blade. Segmented blades are the best option when water is not available. Segmented blades are not recommended for cutting tiles, the blade is going to chip the tile, leaving an awful finish.

Sintered metal-bonded diamond blades are the most common type of blade which are made by combining synthetic diamond crystals with metal powder and then sintering them.

Usage

• Make multiple shallow cuts instead of a single deep cut
• Do not side-grind a cutting blade
• Fit the blade in the correct rotation direction
• The life expectancy and cutting performance of the blade will be reduced when fitted reversed
• It is also prone to becoming glazed
• When a diamond blade is glazed, it feels smooth to the touch with little to no diamonds exposed
• This happens when the metal bond on the segment is too hard for the material it is cutting
• To rectify - expose more diamonds on the segments by making shallow cuts in a soft, abrasive material like limestone
• A short diamond blade life is a result of using a blade with a soft metal bond on a more abrasive material such as sandstone or asphalt
• Wet cutting will extend the life of the blade
• Select the correct blade for the material
