Built-in vacuum attachment port for efficient removal of dust and debris.  Rubber shield helps keep debris away from operator and from entering the motor. Tool base adjusts allowing up to 5" cutting depth; best for cutting split face block when building retaining walls.  Guide wheels on the tool guard ensure smooth traveling of tool over surface material when base is removed for cutting closer to walls.  Positioning of the tool body can be adjusted (0?-80?) for operator comfort; operates independently of cutting depth for convenience and efficiency.  Base has front and rear cutting guides for increased accuracy.  Ball bearing construction and externally accessible brushes for greater serviceability and longer tool life.  Lock-on button for continuous operation.  Rubberized wraparound handle for increased control and comfort with reduced operator fatigue.
