For improved cutting efficiency and reduced operator fatigue when cutting concrete and brick material, use this mountable cutting guide —made exclusively for the GS 461 ROCK BOSS® concrete cutter. Just plunge the cutting guide into the material and the guide spike will cling, helping to allow for easier and more comfortable cutting even in longer cuts and in hard, reinforced concrete. The guide is made from hardened and zinc-coated steel for long-lasting durability. The cutting guide also acts as a pivot point, allowing the user to focus more on the alignment of the cut and less on providing the force.
