High Density Ceramic Abrasive Flap Disc, 7 Diameter, 40 Grit

The Weiler Saber Tooth type 27 high-density ceramic aluminum oxide abrasive flap disc features a phenolic backing for reinforcement. It also has a threaded hole for easy attachment to grinding tools. This disc is thicker than standard ones, making it suitable for use on flat, irregular, and curved surfaces. The self-sharpening ceramic aluminum oxide abrasive is more durable than traditional aluminum oxide, allowing for fast material removal rates and aggressive grinding on heat-sensitive materials such as aluminum, stainless steel, and titanium. It produces a high-quality, consistent finish and has a 30-40% longer lifespan than standard flap discs.

Applications for this disc include weld blending, deburring, deflashing, edge chamfering, stock removal, and grinding and finishing in one step. It is commonly used with right-angle grinders at a 0- to 15-degree angle to dissipate heat. The threaded hole fastening type indicates that the disc has a female-threaded central hole that twists onto a threaded arbor.

Abrasive flap discs are made from overlapping pieces of coated abrasive attached to a hub. They help reduce finishing time and cost by combining grinding and finishing into one step, such as removing a weld bead and smoothing the workpiece around it. Flap discs are coated with an adhesive that attaches abrasive grains to a backing of paper, plastic, or cloth. The action of a flap disc is similar to a sanding disc, with grinding or polishing occurring on the face of the disc. They are used for various applications, from shaping a part to fine finishing, depending on the grit size.

Weiler is a manufacturer of precision brushes, abrasives, and maintenance products. Founded in 1898 in Germany, the company is headquartered in Cresco, PA, and is ISO 9001 certified. Ceramic aluminum oxide is a self-sharpening grit that is harder, tougher, and longer-lasting than aluminum oxide, making it ideal for heat-sensitive materials. The type 27 depressed center flap style is specifically designed for weld blending, deburring, deflashing, edge chamfering, stock removal, and grinding and finishing in one step. The phenolic backing prevents the disc from scratching the workpiece and offers durability and reinforcement. With high-density abrasive and larger flaps, this flap disc has a prolonged life compared to standard ones. The threaded hole allows for easy attachment to grinding tools.
