SMT 324 Extra - abrasive mop disc for stainless steel and steel

The abrasive mop disc SMT 324 Extra has been designed for universal edges and surface work and is used on such materials as

• stainless steel 
• steel.

The abrasive stands out with its excellent removal rate and is held in equally high regard by professional users and do-it-yourselfers. Anyone attaching prime importance to finishing their work swiftly and with excellent results will benefit during their daily routine from the exceptional qualities of the SMT 324 Extra. This abrasive mop disc is convex shape. This shape allows for high aggression due to the small contact area. It is, therefore, ideal for work on edges and for grinding weld seams.

Superior abrasive performance thanks to zirconia alumina

The grain chosen for this product is tried-and-tested zirconia alumina. The disc is made up of a high-quality glass fibre backing plate that is extremely durable. The disc is extremely effective with low power angle grinders. The disc will not glaze even if used at a low grinding pressure. The result is significantly improved handling combined with outstanding results and surface finishes of exquisite quality. The SMT 324 Extra is available in a variety of grit sizes and diameters. The permissible speeds vary depending diameter used.

The benefits at a glance

Optimised performance

The abrasives used have also been engineered to work with high-speed angle grinders (80 m/s) and are designed to offer a wide range of possible applications. The optimised arrangement of the grinding flaps ensures first-rate grinding performance, long service lives and optimised utilisation to the end.

Sustained high performance

The cloth flaps are coated with zirconia alumina, ceramic or aluminium oxide and spaced equally on the backing plate. The optimised cloth-reinforced backing guarantees the operator a fresh grit and, thus, consistent removal throughout the entire work process.

Extraordinary stability


The backing plates included in our SMT range are made of glass fibre or glass-fibre reinforced plastic. They are extremely hard-wearing and deliver optimal power transmission to the work piece.

Tried-and-tested safety

A special manufacturing process ensures an exceptionally strong bond between baking plate and grinding flaps and produces a level of break resistance that easily exceeds the provisions of the oSa and EN 13743 standards.
