Unlike conventional abrasive discs, Cubitron II uses precision-shaped ceramic abrasive grain that cuts into the work surface rather than plowing across it, producing faster cutting speeds, lower heat generation, and longer disc life compared to standard mineral abrasives.\u003c\/p\u003e\n\u003cp\u003eThe net-style abrasive construction allows dust to pass through the full sanding surface rather than relying on a fixed hole pattern, making it particularly effective with vacuum-assisted sanding systems. At P80+, this disc is at the aggressive end of the Cubitron II Net range — suited to initial shaping, stripping, and fairing work before stepping up to finer grades.\u003c\/p\u003e\n\n\u003ch3\u003eIntended Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMarine fiberglass and composite surface preparation\u003c\/li\u003e\n\u003cli\u003eGelcoat and paint removal\u003c\/li\u003e\n\u003cli\u003eFairing compound initial sanding\u003c\/li\u003e\n\u003cli\u003ePrimer and substrate preparation\u003c\/li\u003e\n\u003cli\u003eBody filler shaping\u003c\/li\u003e\n\u003cli\u003eGeneral aggressive surface leveling\u003c\/li\u003e\n\u003cli\u003eAutomotive refinishing preparation\u003c\/li\u003e\n\u003cli\u003eWood and composite sanding where P80+ is appropriate\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eGrade Selection Guide – 6 in.

This results in more consistent dust removal, cooler cutting, and better surface visibility during sanding. It requires a compatible vacuum-assisted sander for full benefit.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is P80+ the same as P80?\u003c\/strong\u003e\u003cbr\u003eA: The 80+ designation is 3M’s official grade marking for this disc, indicating performance equivalent to or exceeding a P80 conventional abrasive. In practice it cuts aggressively at the P80 level and is used in the same applications.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What backup pad size is required?\u003c\/strong\u003e\u003cbr\u003eA: A 6 in. \/ 150 mm Hookit-compatible backup pad is required.

The most common ordering issue is customers mixing up the grade numbers within the 31650–31656 family, so it’s worth confirming the grade alongside the diameter before placing an order. The net construction only delivers its full dust-extraction advantage when used with a properly connected vacuum system — running it without extraction works, but the disc will load faster and cut speed will drop sooner.\u003c\/p\u003e","brand":"WEST","offers":[{"title":"Default Title","offer_id":43564288081956,"sku":"THR-31650","price":165.91,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/ff65cb7e-2035-4b47-8488-74366287893d.png?v=1788845541","url":"https:\/\/marisolmarine.com\/products\/3m-cubitron-ii-net-disc-roll-6in-p80-50-pack-thr-31650","provider":"Marisol Marine Company","version":"1.0","type":"link"}
