It features a closed-coat, resin-bond construction on a C-weight paper backing, delivering consistent cut and finish on hard materials such as stone, glass, ceramics, and non-ferrous metals. At 240 grit, this disc is suited for fine intermediate sanding and surface prep steps where a smooth, uniform finish is required before final finishing stages. Each case contains 100 discs, making it a practical stock unit for production shops and trade professionals who run high disc volume.\u003c\/p\u003e\n\u003cp\u003eThis disc is used in grinding, sanding, and finishing operations across metalworking, auto body, woodworking, and general fabrication environments. The waterproof construction allows use with water or cutting fluid, which helps control heat buildup, extends disc life, and reduces loading on difficult materials. The PSA backing provides a fast, tool-free mount to compatible foam or hard backup pads, minimizing downtime during disc changes. Typical users include metal fabricators, body shop technicians, and finishing tradespeople who require a reliable coated abrasive for wet-process work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSilicon carbide abrasive mineral for effective cutting on hard, dense, and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003e240 grit rating for fine intermediate sanding and pre-finishing surface prep\u003c\/li\u003e\n  \u003cli\u003eClosed-coat construction maximizes abrasive coverage for consistent finish quality\u003c\/li\u003e\n  \u003cli\u003eResin bond holds abrasive grain firmly during wet or dry use\u003c\/li\u003e\n  \u003cli\u003eC-weight paper backing balances flexibility and stability for flat and contoured surfaces\u003c\/li\u003e\n  \u003cli\u003ePSA backing mounts directly to compatible backup pads without fasteners or clamps\u003c\/li\u003e\n  \u003cli\u003eWaterproof design supports use with water or cutting fluid for cooler, cleaner cuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with PSA-style backup pads accepting 8-inch diameter discs.

Ensure the backup pad surface is clean and free of adhesive residue before applying a new disc to achieve full contact and secure hold. When using with water or fluid, verify that the power tool is rated for wet-process operation per applicable safety standards. Worn or loaded discs should be replaced promptly to maintain cut quality and avoid uneven surface results.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Silicon Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 240\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAttachment Style\u003c\/strong\u003e: PSA (Pressure-Sensitive Adhesive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoat Type\u003c\/strong\u003e: Closed Coat\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBond Type\u003c\/strong\u003e: Resin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Weight\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWaterproof\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePack Quantity\u003c\/strong\u003e: 100 Discs per Case\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.046 pounds (per disc)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ARC ABRASIVES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 35121TPL\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ARC ABRASIVES","offers":[{"title":"Default Title","offer_id":51342789673266,"sku":"35121TPL","price":281.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310467903.jpg?v=1782006712","url":"https:\/\/voomisupply.com\/products\/arc-abrasives-35121tpl-psa-silicon-carbide-disc-240-grit-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
