Weiler 34173 Crossflex Standard Duty Bore Brush 18mm Diameter, 320SC Grit

The Weiler 34156 Crossflex Standard Duty Bore Brush seems to provide mixed results for customers. While some users have found it to be of better quality and effective in removing material, others have experienced issues with the longevity and fit of the brush. One customer mentions that the brush started to come apart fairly quickly. This raises concerns about the durability of the product and its ability to withstand heavy use. However, another user who was initially hesitant to purchase the brush was pleasantly surprised by its performance. They found that it quickly removed material from aluminum sleeves without the need for sanding on a lathe. It is worth noting that some customers had issues with the fit of the brush. One user tried using it on a .535 bore and it broke after only 4 seconds of use at slow speed. Another customer attempted to use it on a .498 bore but found that the fit was too tight. These experiences suggest that the brush may not have a universal fit for all bore sizes. Overall, the Weiler 34156 Crossflex Standard Duty Bore Brush seems to have mixed reviews. While it may work effectively for certain applications, durability and fit issues raise concerns about the longevity and versatility of the product.
