CS Unitec's concrete grinders remove epoxy, paint, and other coatings, and smooth rough surfaces. Two 5-inch diameter models are for handheld use. They feature an integrated shock-absorbing system, reducing fatigue and increasing operator comfort. The EBS 125 has a 1500-watt motor, while the EBS 1801 has an 1800-motor. Each is available with a walk-behind cart. Grinders come with a built-in vacuum port for dust-free operation; motors are vertically located away from the dust flow zone.
