Built with a high-strength, very fine (VFN) abrasive material and a durable nonwoven web, this cross buff delivers consistent results on deburring, satin finishing, denibbing, defuzzing, and surface preparation work. The 2-ply staggered design maintains contact uniformity through the bore and resists premature breakdown under production-rate use. At 1 inch in diameter and 3\/8 inch in width, it mounts on a standard 8-32 threaded mandrel. Licensed machinists, toolroom technicians, and aerospace and automotive production technicians are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis cross buff is suited for use on inside diameters of lifter bores, valve bodies, valve spools, tubing, and dies and molds. It handles tasks such as removing surface oxidation and rust, removing corrosion, and preparing surfaces prior to coating or finishing. The aerospace and automotive markets are the primary end-use environments, though any production application requiring repeatable interior bore finishing will benefit from the consistent abrasive action of this geometry. Sold individually, with a minimum order quantity of 100 units.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-strength very fine abrasive grade for controlled material removal without aggressive cutting action\u003c\/li\u003e\n  \u003cli\u003e2-ply staggered nonwoven web construction provides uniform contact and extended service life\u003c\/li\u003e\n  \u003cli\u003e1 inch diameter by 3\/8 inch width fits standard inside-diameter finishing applications\u003c\/li\u003e\n  \u003cli\u003e8-32 threaded mounting stud for compatibility with standard mandrel setups\u003c\/li\u003e\n  \u003cli\u003eSuited for deburring, satin finishing, denibbing, defuzzing, corrosion removal, and pre-coat surface prep\u003c\/li\u003e\n  \u003cli\u003eProven design for aerospace and automotive production environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on inside diameters including lifter bores, valve bodies, valve spools, tubing, and dies and molds in aerospace and automotive production applications.

Confirm the mandrel is fully de-energized and the spindle is stopped before mounting or removing the buff. Follow the tool manufacturer and workpiece material guidelines for appropriate RPM range. Wear appropriate eye protection and respiratory protection when operating abrasive tooling in enclosed or low-ventilation areas.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePly\u003c\/strong\u003e: 2-Ply\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMounting Thread\u003c\/strong\u003e: 8-32\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Grade\u003c\/strong\u003e: High Strength Very Fine (VFN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSold As\u003c\/strong\u003e: Each\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 100\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 00048011644462\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: 3M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7000121124\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"3M","offers":[{"title":"Default Title","offer_id":51344233726258,"sku":"7000121124","price":431.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310523512.jpg?v=1782032381","url":"https:\/\/voomisupply.com\/products\/3m-7000121124-cross-buff-1-inch-x-3-8-inch-2-ply-abrasive","provider":"Voomi Supply","version":"1.0","type":"link"}
