The Mirka Quick Disc CER 38 mm is a ceramic quick lock abrasive disc built for small-area grinding, deburring, and surface preparation. This is a quick lock abrasive disc designed for stock removal and detail grinding on tight, controlled work areas. For this SKU, the model number is 8090385012, and the listed grit variant is P120.

What makes this disc worth paying attention to is the ceramic abrasive itself. Mirka uses self-sharpening ceramic grains, which means the abrasive stays productive longer instead of dulling off early. On the job, that translates into a disc that keeps removing material efficiently during blending and cleanup instead of glazing over and forcing frequent swaps.

The coating and backing matter too. This disc uses a top size treatment and a medium-closed coating to help reduce heat in the grinding zone. That is important when you are working on metal surfaces where heat buildup can discolor the workpiece or leave burn marks. The Y polyester backing also adds durability, so the disc is better suited for demanding grinding work than lighter-duty abrasive constructions.

The 38 mm diameter is a practical size for detail work. It gives you better access on contours, edges, weld cleanup, and smaller contact points where full-size sanding discs are overkill. If your work regularly involves controlled spot grinding instead of broad surface sanding, this size makes more sense because it keeps the cut focused and easier to manage.

System fit is straightforward. This quick lock disc is listed as suitable for the Mirka ANGOS ARG-B, so it is aimed at users already working within that compact grinding platform. That makes it a good fit for trades and shops that need a fast-change abrasive solution for metalworking tasks where maneuverability matters just as much as cut speed.

The P120 grit version is the choice for users who need a finer step in the grinding process than coarse stock-removal grits. It is well suited for refining a surface after heavier removal, cleaning up edges, and preparing material for the next finishing step. If you are doing detail metal prep and want a ceramic quick disc that balances cut, control, and service life, this Mirka abrasive disc is the right kind of product.

Small Disc, Serious Metal Prep Value
