Attention! Stark Abrasive's holiday schedule

3M™ Flap Disc 769F – is our durable, high-performance abrasive flap disc with precision-shaped grains from 3M™ Precision-Shaped Grain and durable polyester base.

3M™ Flap Disc 769F – convenient, strong, efficient and universal petal disc. Our discs are coated with 3M™ Precision-Shaped and proven to be more effective than traditional zirconium corundum petal discs. This abrasive is constantly breaking down to form sharp particles that cleanly cut metal, unlike traditional abrasives that tend to plow through the substrate. This breaking down into particles, together with the destruction of individual petals to release fresh layers of mineral, ensures a high grinding speed that is stable throughout the life of the disc. Polyester base additionally extends durability. Together with the high adhesion, this makes the discs an ideal choice for high-pressure jobs such as beveling, grinding welds and deburring edges. In addition, they create clean surfaces, which makes them indispensable for smoothing and surface preparation. In many cases, 3M™ Flap Disc 769F provides sanding and finishing without changing the abrasive tool. This is possible because under normal conditions the 769F disc finish is one step thinner than a fiber disc of the same grade. Although the fiber disc grinds faster, this petal disc simplifies the process flow, eliminating the need to change tools, which saves time and increases productivity. An ideal choice for processing carbon steel, stainless steel and other alloys sensitive to high temperatures.

Petals End Conical Disc 3M ™ 577F with P40 grain and 125mm diameter consists of aluminum zirconate in a dense polyester base. It is used for hard metals, stainless steel.
