MIRKA Galaxy Sanding Discs - 175mm, 50 Pack

Mirka Galaxy sanding discs are built for performance and longevity. Featuring advanced ceramic grains that self-sharpen as they wear, Galaxy discs maintain a consistently high cut rate across their entire surface. When an edge breaks, new sharp edges form—delivering fast, efficient sanding with a longer lifespan.

Designed as a true all-rounder, Galaxy is ideal for sanding both hard and soft materials across multiple industries, including automotive, marine, wood, and manufacturing. With superb edge wear resistance, a dust-repellent coating, and optimal clogging control, these discs pair perfectly with dust extraction systems for cleaner, healthier work environments.

The ceramic grains of the Galaxy are engineered not to dull, as once the edge of the abrasive grain breaks off it simply forms new edges, making it possible for the Galaxy to continue cutting – from edge to edge. The self-sharpening ceramic grains allow for a winning combination of long life, fast cut and easy polishability. At its core, the Mirka Galaxy is a multi purpose product, suitable for the sanding of both soft and hard materials as well as various substrates. Superb edge wear resistance, excellent clogging resistance, dust repellent coating, and optimal dust extraction - the Mirka Galaxy serve well in the automotive sector, in vehicle manufacturing, collision repair, marine production as well as in the wood sector.

FAQs

• What makes Mirka Galaxy different from other abrasives? Mirka Galaxy abrasives feature self-sharpening ceramic grains, which keep the abrasive sharp throughout its use, making them longer-lasting and more efficient.
• How does the self-sharpening technology work? As the abrasive grains wear down, they break apart to form new sharp edges, maintaining consistent cutting performance over time.
• What materials can Mirka Galaxy abrasives be used on? They are versatile and can be used on a wide range of materials, including wood, metal, composites, painted surfaces and more.
• Are Mirka Galaxy abrasives compatible with dust extraction systems? Yes, they feature multi-hole patterns for optimized dust extraction, which helps maintain a cleaner work environment and improves the sanding process.
• How durable are Mirka Galaxy abrasives? Mirka Galaxy abrasives are designed to be highly durable due to their self-sharpening ceramic grains and clog-resistant coating, which reduces the build-up of dust and debris.
• Can Mirka Galaxy be used for both rough and fine sanding? Yes, they come in a range of grits, from coarse to fine, making them suitable for various stages of sanding, from heavy stock removal to finishing.
• What are the available grit sizes for Mirka Galaxy? Mirka Galaxy abrasives are available in a wide range of grit sizes, typically ranging from P40 to P2000, depending on the specific application.
• Are Mirka Galaxy abrasives suitable for machine or hand sanding? They are designed for both machine and hand sanding, but they are most effective when used with orbital or random orbital sanders.
• How do Mirka Galaxy abrasives help save time and money? The long-lasting self-sharpening grains, resistance to clogging, and compatibility with dust extraction systems reduce the need for frequent abrasive changes, leading to faster work and lower costs.
• What industries benefit most from using Mirka Galaxy abrasives? They are ideal for industries such as woodworking, automotive refinishing, marine, and metal fabrication, where versatility and efficiency are key.
