4-1/2″ Trimmable Zirconia Flap Disc – Type 29 The 4-1/2″ Trimmable Zirconia Flap Disc – Type 29 is designed for aggressive grinding and extended disc life in demanding metalworking applications. Constructed with premium zirconia grain abrasive flaps and a trimmable plastic backing, this disc allows the backing to be trimmed as the flaps wear, ensuring full use of the abrasive face and maximizing overall disc life. The Type 29 angled flap design provides a higher angle of attack for fast material removal, making this disc ideal for edge grinding, weld blending, and heavy stock removal. Zirconia alumina grain is extremely tough and self-sharpening, delivering consistent cutting performance under heat and pressure throughout the life of the disc. Key Features Premium Zirconia Alumina Grain – Tough, self-sharpening abrasive for extended disc life Trimmable Plastic Backing – Enables full use of abrasive flaps as the disc wears Type 29 Angled Design – Ideal for aggressive grinding and edge work High Heat Resistance – Performs well under heavy pressure applications Long Service Life – Reduces disc change-outs and increases productivity Ideal For Carbon steel Stainless steel Aluminum Fiberglass Plastic Weld grinding and blending Edge grinding and stock removal Specifications Disc Diameter: 4-1/2″ Abrasive Grain: Zirconia Alumina Disc Type: Type 29 (Angled) Backing Material: Trimmable plastic Application: Grinding and blending Mounting: Standard angle grinder
