Mark-III Dust Buggy  

The Mark-III is a high performance; high precision saw designed to clean out control joints, remove the old joint filler, and make straight, accurate cuts in concrete up to 2″ deep. A specially designed blade guard allows the operator to see the blade yet still covers 98% of it for excellent dust control and a high degree of accuracy. The handle and frame are designed for more stability and adjustable height that rotates to get closer to walls or racks.

The aluminum alloy chassis has a lifetime warranty and is powered by a 120V 15 amp Metabo 24-230 (6,600 RPM).

The Mark-III uses 7 or 8″ blades up to 3/8″ (.375) wide, blade depth is fully adjustable and has a depth lock to prevent overcutting.
