Measuring 3 inches in diameter, it features a 150-grit aluminum oxide abrasive bonded to a flexible cloth backing. The very fine grit rating makes it well-suited for finish sanding, light material removal, and surface preparation prior to coating or polishing. The PSA mount allows for fast, tool-free attachment to compatible backup pads, reducing changeover time during production or detail work. Machinists, metalworkers, woodworkers, and general fabricators commonly use this disc format.\u003c\/p\u003e\u003cp\u003eThis disc is intended for use on bench-top or handheld rotary and random-orbit sanders fitted with a 3-inch PSA backup pad. The flexible cloth backing conforms to slightly contoured surfaces, making it a practical choice for both flat stock and light contour work. It is sold as a single disc and is appropriate for both shop and field use where fine finish work is required on wood, metal, composites, or painted surfaces.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e150-grit aluminum oxide abrasive provides very fine cutting action for finish sanding\u003c\/li\u003e\n\u003cli\u003eFlexible cloth backing conforms to surface contours without tearing\u003c\/li\u003e\n\u003cli\u003ePressure-sensitive adhesive backing enables fast, tool-free pad attachment\u003c\/li\u003e\n\u003cli\u003e3-inch diameter fits standard PSA backup pads for rotary and random-orbit tools\u003c\/li\u003e\n\u003cli\u003eNo vacuum holes — suited for solid backup pads without dust-extraction ports\u003c\/li\u003e\n\u003cli\u003eBlack disc color for easy grit identification in mixed-grit environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 3-inch PSA backup pads on rotary or random-orbit sanding tools.

Before mounting, inspect the backup pad surface for debris or residual adhesive that could cause uneven contact. Do not exceed the maximum RPM rating of the backup pad in use. Worn or glazed discs should be replaced promptly to maintain consistent finish quality and avoid heat buildup on the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 150\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Very Fine\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Pressure-Sensitive Adhesive (PSA)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum Holes\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlexible\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MERIT ABRASIVES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 08834171181\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MERIT","offers":[{"title":"Default Title","offer_id":51558095126834,"sku":"08834171181","price":74.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f6bc0ae07c39ac4399e14f56a0c8048.jpg?v=1786403210","url":"https:\/\/voomisupply.com\/products\/merit-abrasives-08834171181-psa-disc-3-in-150-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
