Abstract

A back grind attachment, kit and method used to make undercuts on a stone slab using a hand grinder. The attachment includes a mounting plate attached to a guide plate. e. Extending downward from the head is an arbor with one or more blades configured to form an undercut in the edge of the stone slab when pressed against the edge. The guide plate extends outward from said mounting plate and includes two wheels that roll against a fence formed on a fence plate. The mounting plate is pivotally attached to said guide plate, enabling it to rotate to one side, which allows the operator to rotate the grinder in an offset position and force the blades inward (deeper cut) or outward (shadow cut) from the edge of the stone slab. A clamping lever holds the mounting plate fixed over the guide plate. A uniform undercut is formed on the edge by simultaneously pushing the wheels against the fence and sliding the guide plate over the fence plate.
