Key Features
Overview
The Mirka 1.5 Inch Quick Disc CER sanding disc, model 8090385080, is a ceramic quick-lock abrasive disc for fast material removal in small, controlled grinding and surface-prep work. This is a quick-lock sanding disc designed for stock removal and grinding in tight areas. Based on the product data and package marking, this version is a P80 grit disc supplied in a 100-pack.
What matters here is the abrasive itself. Mirka uses self-sharpening ceramic grains, which means the disc is built to stay productive under pressure instead of dropping off fast once the surface starts to wear. For users doing deburring, weld cleanup, edge blending, or general metalworking prep, that translates into quicker cutting and fewer disc changes during the job.
The backing and coating setup are just as important as the grit. This disc uses a Y polyester backing along with top size and a medium-closed coating. In practical terms, that combination gives the disc more durability while helping manage heat in the grinding zone. Less heat means a lower chance of burn marks on the work surface and more consistent performance when you’re working across multiple parts.
The compact 38 mm / 1.5 inch diameter is the whole point of this format. It is made for smaller work areas where a full-size grinding disc or sanding disc is overkill. If you need to get into tighter spots, work around contours, or clean up a localized area without touching a bigger surface than necessary, this size makes more sense than stepping up to a larger abrasive.
Speed rating matters with small surface-conditioning accessories, and this one is clearly marked. The package lists a maximum speed of 38,200 RPM and 80 m/s. That gives you a clear operating ceiling for matching the disc to the right tool and using it safely within the intended range.
On system fit, Mirka states this ceramic quick disc is suitable for the Mirka ANGOS ARG-B. That is useful if you’re already running Mirka’s tool platform and want a matched abrasive for detail grinding or surface prep. For buyers already invested in Mirka accessories and finishing products, this keeps the setup straightforward.
Who should buy this? This disc makes the most sense for metalworking, fabrication, automotive refinishing prep, and any shop work where small-area grinding and controlled stock removal matter. If you need a general finish disc for broad flat panels, this is not the format. If you need a durable ceramic quick disc that cuts hard, runs in tight spots, and comes in job-ready quantity, this is the right kind of abrasive.
Fast Cutting in Small Work Areas
This disc is built for users who need the cut rate of ceramic abrasive without stepping up to a larger disc. The compact format lets you stay precise while still removing material quickly.
- Self-sharpening ceramic grain supports aggressive stock removal
- P80 grit is a practical choice for grinding and surface prep where you need a balance of cut and control
Built to Run Cooler and Last Longer
Mirka did not just spec a hard-cutting grain and call it done. The backing and coating package is aimed at durability and heat control, which is what keeps an abrasive useful over a longer run.
- Y polyester backing adds strength for demanding grinding work
- Top size and medium-closed coating help reduce temperature in the grinding zone to avoid burn marks
Job-Ready Pack Quantity
Abrasives disappear fast in production work, so pack size matters. This version comes boxed in a 100-count, which makes more sense for regular shop use than buying a few discs at a time.
- 100 pieces per pack for restocking carts, benches, or production stations
- Package is marked with max speed of 38,200 RPM and 80 m/s for quick reference

Pro Tip
If you’re using this P80 ceramic disc for cleanup on small metal parts, let the abrasive do the work and keep it moving. Leaning too hard on a small disc usually builds heat faster than it gains cut.
Tool Nut’s Take
Small disc, serious removal
The Mirka 1.5 Inch Quick Disc CER sanding disc is the kind of abrasive you buy when you need a compact disc that still works like a production tool.
- Who it’s for: Fabricators, automotive techs, and anyone doing controlled grinding or prep work in small areas.
- Why it stands out: Ceramic grain for real cut speed, heat-conscious backing and coating, and a 100-pack that makes sense for regular use.
- Worth knowing: This is a specialized small-format quick disc, not a general-purpose broad-area sanding solution. It shines when access and control matter.
