Powertrain Polishing

Repeatable Performance, Reliable Partner

Mirka’s abrasive films are what you need to achieve consistent functional surface values in your superfinishing or polishing operation. Featuring an anti-slip dot pattern on the back, we offer two different film products to help you easily select the right product for your specific polishing needs.


Cost-Saving With Greater Stock Removal Using MI231C 

Abrasive film product designed for the coarse and fine polishing of powertrain components. The product is more aggressive than standard aluminium oxide films, but produces a fine surface scratch pattern. Fast cutting and resistant to surface loading, MI231C is sure to shorten cycle times.

Consistent Quality Through Consistent Polishing With MI231A

Abrasive film product designed for the fine polishing of powertrain components. Fine cutting and resistant to surface loading, MI231A produces a consistently extra-fine surface scratch pattern.
