CGW 35840 7" X 7/8" Type 29 24-Grit Brown Aluminum Oxide Red Fiber Backing Semi-Flex Disc

The CGW 35840 disc is a 7 inch diameter Type 29 semi-flex grinding wheel designed for versatile material removal and surface shaping. Constructed with a brown aluminum oxide abrasive on a red fiber backing, this 24-grit disc balances aggressive material removal with a semi-flex backing that accommodates contoured or irregular surfaces common in metal and composite work. The Type 29 configuration positions the grinding grain for use on a right-angled grinder, enabling efficient feathering and finishing of curved profiles and flush joints.

This disc is suitable for a range of applications where durable aluminum oxide performance is preferred, including roughing castings and metal components such as cold-rolled steel, stainless steel, bronze, aluminum, and iron. The abrasive choice supports effective material disruption while maintaining manageable heat generation and edge stability. Its 7/8 inch arbor/shank size and 8600 RPM rating specify the mounting and speed parameters required for compatible tooling and power sources, helping operators select appropriate grinders and prevent overspeed conditions. Each package contains 25 discs, offering economical supply for recurring maintenance tasks.

When selecting this disc, consider the workpiece geometry and coating removal needs—the 24-grit aluminum oxide abrasive is optimized for faster material removal rather than fine finishing. The semi-flex backing provides a balance between rigidity and conformability, enabling smooth contact with varied surfaces while maintaining control. Ensure proper PPE and follow tool manufacturer recommendations for mounting, guard clearance, and wheel speed limits to sustain consistent performance and safety during routine facility maintenance tasks.
