Abrasive Grinding Wheel For Fiberglass is Flexible and Won’t Clog


A new, all-purpose flexible mesh abrasive wheel for the grinding and light sanding of fiberglass tanks, vessels, hulls, and composite structures has been introduced by Rex-cut Products, Inc. of Fall River, Massachusetts.

Sigma-Screen™ Multipurpose Discs are depressed center Type 27 abrasive wheels that feature a blend of zirconia-ceramic abrasive grains bonded to a flexible mesh and come in coarse, medium, fine, and very-fine grades. Ideal for the grinding, blending, and light sanding of fiberglass and composites, these mesh abrasive wheels are chatter-free and won’t clog.

Faster and cooler on fiberglass than solid resin fiber discs, Sigma-Screen™ Multipurpose Discs are offered in a test kit featuring two-each of coarse, medium, fine, and very-fine to let fabricators evaluate them. These 4.5” dia. wheels can be stacked on a grinder for longer life. They are also effective for stainless steel, metals, aluminum, and wood.

The Sigma-Screen™ Multipurpose Disc Kit is priced at $ l8.74 (list). Individual discs are $1.99 (list) ea., supplied in boxes of 10 and 50 discs; with quantity discounts available.
