High Density Ceramic Abrasive Flap Disc, 4-1/2 Diameter, 40 Grit - Weiler 50133

The Weiler Saber Tooth type 27 high-density ceramic aluminum oxide abrasive flap disc features a phenolic backing for reinforcement and a threaded hole for easy attachment to grinding tools. This disc is thicker than standard discs, 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 like aluminum, stainless steel, and titanium. It delivers a high-quality, consistent finish and boasts a 30-40% longer lifespan compared to standard flap discs.

Applications for this disc include weld blending, deburring, deflashing, edge chamfering, stock removal, and one-step grinding and finishing. It is designed with a flat surface and is commonly used with right-angle grinders set at a 0- to 15-degree angle to help dissipate heat effectively. The threaded hole fastening type indicates a disc with a female-threaded central hole that can be twisted onto a threaded arbor.

Abrasive flap discs are constructed from overlapping pieces of coated abrasive attached to a hub, speeding up finishing processes and reducing costs by combining grinding and finishing into one step. These discs are coated with adhesive to attach abrasive grains to a backing made of paper, plastic, or cloth. Their action is similar to that of a sanding disc, with grinding or polishing occurring on the face of the disc. Flap discs can be used for various applications, from shaping parts to achieving a fine finish, depending on the grit size. Lower grit numbers like 40 are considered coarse, removing excess material and shaping parts, while higher grit numbers like 400 are finer, helping to create a smooth surface finish.

Ceramic aluminum oxide is a self-sharpening grit known for being harder, tougher, and longer-lasting than aluminum oxide. The Type 27 depressed center flap style of this disc is ideal for various applications, making it a versatile and durable choice for grinding and finishing tasks. Its phenolic backing ensures that the disc does not scratch the workpiece while offering durability and reinforcement. High-density abrasive and larger flaps contribute to a prolonged lifespan compared to standard flap discs, making it a reliable option for professionals. The threaded hole design allows for quick and secure attachment to grinding tools, ensuring ease of use and efficiency in operations.
