Mark-IV Dust Buggy - Joint Clean Out Machine

The Mark-IV 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.

When the Mark-IV is paired with the Tiger Tooth Blades, this machine will remove polyurea joint filler.

The aluminum alloy chassis has a lifetime warranty and is powered by a 120V, 15-amp Metabo W24-230.

The Mark-IV Dust Buggy comes with an 8″ x .125 x 7/8-5/8 Supreme Concrete Blade and can accommodate 7″ or 8″ blades up to .375″ wide. It features a fully adjustable blade depth and includes a depth lock to prevent overcutting.

Recent Added Features: A new motor bracket makes grinder changes faster and easier. The new blade guard allows even more visibility of the blade, and the new control box features a magnetic switch that eliminates accidental re-starts and an all in one voltage and amperage gauge to allow the operator to to push the limits without burning out the grinder.
