Weiler 50136 Saber Tooth High Density Abrasive Flap Disc, Flat, Phenolic Backing, 7/8" Arbor, Ceramic, 7" Diameter, 40 Grit (Pack of 10)

The Weiler Saber Tooth type 27 high-density ceramic aluminum oxide abrasive flap disc has a phenolic backing for reinforcement and an unthreaded round hole for attachment to grinding tools, and is thicker than a standard disc for use on flat, irregular, and curved surfaces. The ceramic aluminum oxide abrasive is self-sharpening and more durable than aluminum oxide, which makes it suitable for fast material removal rates and aggressive grinding on heat-sensitive material such as aluminum, stainless steel, and titanium. It produces a high-quality, consistent finish and has a 30-40% longer life than standard flap discs. Applications include weld blending, deburring, deflashing, edge chamfering, stock removal, and grinding and finishing in one step. The disc has a flat surface and is commonly used with right-angle grinders at a 0- to 15-degree angle to dissipate heat. It has an unthreaded round hole for attachment to the grinding tool. The tool's arbor goes through the central hole in the disc for fastening. Abrasive flap discs are made from overlapping pieces of coated abrasive attached to a hub. They help reduce finishing time and cost by grinding and finishing in the same step, such as when removing a weld bead and smoothing the workpiece around the weld. Flap discs are coated, meaning an adhesive is used to attach the abrasive grains to a backing of paper, plastic, or cloth. The action of a flap disc is much like that of a sanding disc: the grinding or polishing occurs on the face of the disc. They are used for a variety of applications from shaping a part to fine finishing, depending on the grit size. Low grit numbers like 40 are coarse (with fewer, larger grains) and remove excess material and shape parts. High grit numbers like 400 are fine (with more, smaller grains) and help create a smooth surface finish. Weiler manufactures precision brushes, abrasives, and maintenance products. The company was founded in 1898 in Germany, is headquartered in Cresco, PA, and is International Organization for Standardization (ISO) 9001 certified.
