In this video we are testing out the "4 Inch Concrete Stone Ceramic Turbo Diamond Grinding Cup Wheel,12 Segs Heavy Duty Angle Grinder Wheels for Angle Grinder (Yellow)" from Amazon and grinding a drainage channel into concrete. This Grinder wheel is designed to cut concrete with a standard 4 inch or 4.5 inch angle grinder. The grinder I am using is a Porter Cable PC750AG 7.5 amp grinder. We are cutting concrete dry rather than wet cutting which creates a lot more dust and will require use of PPE like a 3M respirator. This is a relatively good way to fix a puddle in an old concrete driveway or shape concrete if necessary.
