Eliminating the backing pad and tapered flange nut from portable grinding wheel securement results in a lighter unit to ease operator control and comfort and reduce fatigue.

Metabo Corporation, a leading international manufacturer of professional grade portable electric power tools and abrasives for various industrial, construction and welding applications, has introduced the Type 29 Z-Plus grinding wheel that eliminates the need for a backing pad and tapered flange nut. The Type 29 Z-Plus weighs less than half of a typical 4-1/2in grinding wheel. This significantly increases the operator's control and comfort while decreasing fatigue, particularly with small grinders used in tight spaces and at odd angles.

The wheel's slightly concave profile also lessens the grinder's angle of attack, reducing operator fatigue.

The Type 29 Z-Plus, with its aluminum oxide abrasive, is well suited for blending and surface weld removal on steel, stainless steel and aluminum.

The wheel, a refinement of Metabo's Type 29 grinding wheel, can also be used to grind other non-ferrous metals, as well as most plastics and resin or fiberglass-based structural materials.

The Type 29 Z-Plus is available in 4-1/2in or 7in diameter, with a 7/8in arbor or 5/8in-11 hub.
