Flex-Hone Editorial Review

The Brush Research GB31224 FLEX-HONE is an effective honing tool used for deglazing cylinders in engines for new rings. It is available in various sizes and grits of 60, 80, 120, 180, 240, 320, 400, and 600. The tool works best when the correct size is chosen and the recommended speed and technique for honing are followed. Although the product is not suitable for removing large amounts of material, it is effective for its intended use. Several customers have purchased and used this product with success, saving them time and money compared to alternative methods of glazing. However, some potential buyers have expressed difficulty when choosing the correct size brush, and some criticism has been regarding the tool's inability to remove more significant amounts of material.
