CGW 41702 4-1/2" X 7/8" Type 27 40-Grit ZPC Zirconia Flap Disc

The CGW 41702 is a 4-1/2 inch by 7/8 inch arbor Type 27 Zirconia flap disc designed for heavy grinding on steel. Its zirconia grain is paired with a poly/cotton backing, which contributes both durability and a consistent finish during material removal. The Type 27 configuration provides a flatter grinding surface suitable for access to contoured or angled workpieces, making it a practical choice for grinding welds, deburring, and smoothing coarse surfaces on steel components.

Key construction notes include zirconia abrasive grain engineered for high cut rates and extended wheel life, coupled with a backing that supports even wear and reduces heat buildup under typical grinding conditions. The disc is rated for up to 13,300 RPM, aligning with standard high-speed applications while helping ensure controlled aggression and smoother finishes. Each disc is sized for 4-1/2 inch diameter and 7/8 inch arbor, and is packaged as a single unit with a box quantity of 10, facilitating stocking and rotation in busy shop environments.

When selecting for steel-focused tasks, this CGW flap disc offers a robust option for aggressive material removal with a finish-oriented Type 27 profile. Practically, users should match the RPM rating to their grinder and verify arbor compatibility with their tool to avoid improper mounting. Consider routine inspection of the disc surface for wear and periodic replacement to maintain consistent grinding performance and finish quality.
