Product Description

4.5" Silicon Carbide Semi-Flex Sanding Disc with 7/8" Arbor Hole

4.5" x 7/8" Silicon Carbide Semi-Flex discs by BHA feature layers of high-quality silicon carbide grains coated on a vulcanized depressed center / domed backing in a spiral pattern for increased airflow and reduced loading during use. These 4-1/2 inch semi flexible grinding discs get their name from the fact that despite their rigid, stiff-to-the-touch neutral state, they were designed with a slotted and domed center area which allows for some flex during use. BHA’s semi-flex sanding discs are engineered with premium silicon carbide grains. Silicon carbide grains are very sharp yet brittle so as the discs are used the abrasive is cracked away producing new fresh sharp edges which allows for consistent cut rate during its useful life. The extreme sharpness leads to a faster cut and finer scratch pattern.

The sharpness and friability of these silicon carbide discs combined makes these sanding discs extremely effective at grinding on non-ferrous materials such fiberglass (boat hulls), quartz, terrazzo, concrete, marble, stone, brick, limestone, quartz, masonry, porcelain, as well as enamels and hooves. However, BHA semi flex vulcanized fiber backed discs truly shine when they are used to remove epoxy, glue, sealants, urethane, rubberized coatings, or mastics. As mentioned above, these discs are load-resistant allowing them to cut through thick, adhesive-type coatings that would ordinarily load up a diamond cup wheel with ease and minimum build up on the disc. These discs are clearly very versatile so it comes as no surprised that they have useful applications in industries ranging from plumbing to ship building to masonry, construction (specifically pre cast and pre stressed concrete), flooring, etc.
