The BlackHawk 1250 Burnisher drives a 20” pad at 1250 RPM for efficient polishing of all hard floor finishes. The 1.5 HP 66 frame AC motor is powerful. The welded steel frame and 2-piece handle are durable and reliable. It is remarkably easy to handle and can be used on all types of hard floors. It is powered by a durable 1.5 HP TEFC (Totally Enclosed Fan Cooled) AC motor that requires little maintenance with a motor shroud that protects the inner working from dust and moisture.
