Diamond Blades for Concrete

Concrete, reinforced concrete, concrete kerbs and pipes as well as concrete pavers require United Diamond Tools "white" blades. They also suit fast cutting of reconstituted limestone pavers.

Green concrete (concrete that has set but not fully hardened or cured) is highly abrasive, so we suggest a United Diamond Tools "black" asphalt blades for longer life.

Newly laid or cured exposed aggregate is best cut with a concrete blade - these blades have excellent undercut protection if you go through to the under base.

Our Premium concrete blades were originally developed for dry cutting in the US market, so are tough and durable and can operate with reduced water that you sometimes get on site.

Note - If you are cutting dry, always be aware of the danger of breathing in the dust. Ensure a dust extraction system is used with a suitable filter fitted. Use a half face respirator or a PAPR (Powered air purifying respirator). Even if you are cutting wet, the slurry created can dry out and create a hazard for other users - dispose of slurry as per your local regulations.
