Surface Conditioning Disc – 4 Inch Diameter, Brown, Aluminum Oxide, 10 Discs per Box

This surface conditioning disc is made with non-woven synthetic fibers combined with aluminum oxide abrasive. It is specifically designed for aggressive surface conditioning, blending, and finishing applications. The disc provides a consistent cut rate and long abrasive life due to its self-fracturing aluminum oxide mineral, which continually exposes fresh cutting edges during use. This results in consistent, effective material removal and finishing performance across various metals. The disc’s durable construction also resists loading and heat buildup, making it suitable for both grinding and finishing operations.
