The DDG 1220 (nicknamed the “Beast”) is an all-in-one grinder, polisher, burnisher and zero-tolerance edger. The DDG 1220 is a variable-speed single-head grinder with flex-head technology powered by a dual-phase (single or three-phase) or a dedicated three-phase 230-volt-480-volt, 7.5-horsepower motor.
The grinder is equipped with a single 12-inch plate, which is adjustable by design to move left or right in order to get right up against the edge of the wall for zero-tolerance edging. The DDG 1220 is engineered with a grinding-head leveling system that allows the operator to adjust the height of the grinding head in order to account for varying tooling heights. In addition, the head of the grinder can be adjusted 20 degrees left or right of center to allow the operator to walk in a straight line while following the edge of the wall. The grinder is equipped with a floating shroud for efficient dust pickup.
This grinder can be fitted with several options, such as an additional weight for additional grinding-head pressure. The grinder head can be retrofitted in minutes with a 20-inch metal- or resin-bond diamond plate and a very low-profile shroud, known as a Toe Kick Shroud, in order to grind under a cabinet toe kick or low racking. In addition, the grinder can be retrofitted to be used as a 20- or 27-inch high-speed burnisher.
