Brush Research BC138180AO FLEX-HONE, 1-3/8" (35mm) Diameter, 180 Grit, Aluminum Oxide, for Aluminum, Brass, Bronze and Softer Non-Ferrous Materials

The Brush Research BC78400AO FLEX-HONE® is a versatile tool designed for honing softer non-ferrous materials such as aluminum, brass, and bronze. Customers have had a mixed experience with this product, with some finding it suitable for cleaning up surfaces but not for resizing or removing large amounts of material. One user inquired about using the hone for resizing connecting rods, to which it was advised that the tool could clean up the surface but not resize. Another potential customer asked about shaving off aluminum to change bore size, and it was clarified that the Flex-hone is a surface finish tool and cannot remove large amounts of material. On the positive side, customers have found the tool effective for specific applications such as crisscross hatching a brass valve guide without removing metal and honing cylinders within a certain size range. However, there have been complaints about the tool's sizing range, with one user mentioning that the 3" hone was too big for their Sea-doo Rotax 587 cylinders. In conclusion, the Brush Research BC78400AO FLEX-HONE® seems to work well for surface finishing softer non-ferrous materials within a specific size range. However, it may not be suitable for tasks that require resizing or removing significant amounts of material. **
