CGW 43181 5" x 7/8" Type 29 36-Grit Calcium Stearate Coated Flap Disc is designed for aluminum and other non-ferrous metal applications. This flap disc combines aluminum oxide grain with a calcium stearate treatment to help keep the surface cooler during use and reduce loading when working soft materials. The 5-inch diameter and 7/8-inch arbor size align with common hand-held grinders, enabling efficient material removal and a smoother finish on aluminum components. The Type 29 angling delivers a progression from rough grinding to finer blending, making it suitable for general purpose surface preparation and deburring tasks on non-ferrous workpieces.
Constructed to support continuous operation in metalworking settings, the disc’s calcium stearate coating serves as a lubricant-like additive that can help manage heat buildup and reduce clogging. This can be particularly beneficial when finishing softer base metals where excessive heat creates undesirable work-hardened edges or loaded discs. While the specification notes 36-grit, the practical result is a robust balance between material removal rate and a finer finish on aluminum surfaces. Operators should ensure proper wheel RPM compatibility and verify fixture clearance for a 5" disc with a 7/8" arbor in their grinder setup.
This product is packaged as individual discs, with a box quantity of 10, making it suitable for maintenance rounds and small production runs. When selecting this flap disc, confirm alignment with your grinder’s arbor size and verify that the Type 29 face orientation suits your access to contoured or recessed areas. Regular inspection for wear and loading is recommended to maintain consistent performance on non-ferrous workpieces.
