CGW 56022 4-1/2" X 5/8"-11 Type 27 40-Grit SC Silicon Carbide Flap Disc

CGW 56022 is a 4-1/2 inch diameter flap disc designed for aggressive material removal and finishing on a variety of substrates. This Type 27 wheel features a 5/8-11 arbor and 40-grit silicon carbide grain, offering sharp cutting action and a clean, smooth finish on prepared surfaces. The polyester backing supports the flap construction, contributing to dependable performance during extended use while resisting loading on tough materials.

The wheel's silicon carbide abrasives are well-suited for use on stone materials such as granite and marble, as well as plastics, fiberglass, and certain metals including titanium and its alloys. This makes the disc a versatile option for applications requiring both stock removal and a finer surface finish. The 40-grit size balances material removal with surface texture, and the Type 27 profile helps maintain the correct angle for efficient grinding and finishing tasks.

Practical considerations include compatibility with standard 4-1/2 inch grinders and a maximum operating speed of 13,300 RPM, which aligns with typical performance ratings for this disc size and grain. Packaged as individual discs with a box quantity of 10, it is suitable for job-site stocking and periodic replacement without over-ordering. When selecting for stone, plastics, or composite materials, verify tool compatibility and the desired surface finish to ensure the disc meets project requirements.
