Common Concerns Answered
Will these discs clog quickly?
While SEM AVS discs are designed for efficiency, they may load up with very soft materials if not used with proper technique or appropriate pressure. Employing a consistent sanding motion minimizes loading.
Is the film backing as good as net for dust extraction?
Some users prefer net-backed discs for superior dust extraction. However, the Advanced Venting System (AVS) on these SEM discs is engineered to enhance airflow and reduce dust, providing a balance of performance and dust management.
Are these discs worth the price?
The SEM AVS 400 Grit discs offer a superior, consistent finish with fast cutting action and extended life due to their precision grain technology and Advanced Venting System. This durability and performance often justify the investment for critical marine finishing tasks.
