The Kodiak Pro Grinding system is a configuration of 6 over-lapping counter rotating heads that provide an aggressive full coverage grind that gets within an 1/8" of a wall eliminating the need for time consuming edging. The 1.5HP VFD controlled motor runs on a 120V 15A circuit and will keep the motor draw voltage within this range to prevent blowing breakers. The 6 counter rotating heads with two magna trap accessories per head provide a consistent grind from prep at 16 grit to polish at 3000 grit. This configuration provides greater performance than similar 20" planetary grinders and is same head configuration as the Werkmaster Grinders
