Trend Delta Sanding Sheet 93mm 40G (10 Pack) Zirconium. This pack contains 10 Trend Zirconium Delta Sanding Sheets, each measuring 93mm and with a grit of 40G. Trend high-performance Delta Sanding Sheets feature a multi-material, long-life zirconium abrasive. They maintain performance 4x longer than conventional abrasives. This self-sharpening grit fractures away during use to expose fresh, sharp-cutting faces, and the abrasive can be rotated when the tip wears for an extended lifespan. An anti-clogging open coat reduces clogging and allows for faster stock removal, especially on gummy, resinous timbers, fillers, and paint removal. The 6-hole punch pattern ensures base compatibility on all popular brands and maximum dust extraction. These sanding sheets excel on harder materials, particularly metals. They are ideal for sanding into corners, removal of old finishes, rust removal, metal finishing, heavy stock removal, and primary preparation work. Hook and loop fixing provides a secure fit to the tool base.
