This is a sanding disc designed for coarse sanding, stripping, and heavy surface preparation. If you're knocking down rough stock, removing paint, or cleaning up metal before the next step, this disc is built for that kind of work.\u003c\/p\u003e\n    \u003cp\u003eThis P36 version is the most aggressive end of the listed grit range, so it is the one you reach for when speed matters more than finish quality. On the job, that means faster removal of old coatings, quicker leveling on rough wood, and more efficient cleanup on steel, stainless steel, cast iron, non-ferrous metal, plastics, and composite materials. Mirka also calls out dust binding properties, which helps keep loading under control during coarse sanding where debris buildup can kill cutting performance.\u003c\/p\u003e\n    \u003cp\u003eWhat makes this product different is the reinforced backing. Coarse abrasives get punished harder than fine grits because users lean on them for stripping and shaping, especially around edges and uneven surfaces. The reinforced construction is there for exactly that reason. It gives the disc more durability in demanding prep work where lighter discs tend to wear out early or lose consistency.\u003c\/p\u003e\n    \u003cp\u003eThe 8 inch grip format matters too. Hook and loop attachment keeps disc changes quick, which is a real advantage when you're moving through multiple stages of prep or replacing worn discs during heavy sanding. Less time fighting the abrasive means more time actually getting work done. For shops and contractors who run through coarse discs regularly, that small time savings adds up.\u003c\/p\u003e\n    \u003cp\u003eMirka lists this abrasive for sanding applications across wood, metal, fiberglass, synthetic materials, chipboard, MDF and HDF, lacquers, paint removal, and more. That makes it a practical choice for bodywork prep, fabrication cleanup, woodworking stock removal, and general refinishing work. It is not a finish sanding disc. It is a first-step abrasive for users who need to remove material quickly and move on to finer grits later.\u003c\/p\u003e\n    \u003cp\u003eThe Mirka COARSE CUT 8\" Grip is best for pros and serious DIY users doing surface prep, stripping, shaping, and rough sanding where durability and cut speed matter more than finesse. If your work starts with ugly surfaces, thick coatings, or stubborn material that needs to go away fast, this is the right kind of disc to have on hand.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-whats-included\" class=\"acc\" open\u003e\n  \u003csummary\u003e\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\u003c\/summary\u003e\n  \u003cdiv class=\"acc-body\"\u003e\n    \u003cdiv class=\"tnincluded-wrapper\"\u003e\n      \u003cul\u003e\n        \u003cli\u003e(25) Mirka COARSE CUT 8\" Grip sanding discs, P36 grit\u003c\/li\u003e\n      \u003c\/ul\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-key-specifications\" class=\"acc\" open\u003e\n  \u003csummary\u003e\u003ch2\u003eKey Specifications\u003c\/h2\u003e\u003c\/summary\u003e\n  \u003cdiv class=\"acc-body\"\u003e\n    \u003ctable class=\"aplusspecs\"\u003e\n      \u003ctr\u003e\n        \u003cth\u003eDisc Diameter\u003c\/th\u003e\n        \u003ctd\u003e8 in.
