Built with aluminum oxide abrasive bonded to a cloth backing, this wheel delivers consistent material removal and a fine surface finish across a range of ferrous and non-ferrous metals. At 4.5 inches in outside diameter and 4 inches wide, it fits standard drum arbors with a 5\/8-11 threaded hole and is rated to a maximum of 3,800 RPM. The interleaf construction helps maintain uniform cut and extends wheel life during continuous use. Installation and operation are handled by grinding equipment operators and metalworkers in fabrication and finishing environments.\u003c\/p\u003e\n\u003cp\u003eThis flap wheel is suited for surface conditioning, deburring, and blending operations on aluminum, stainless steel, and carbon steel. The fine 80-grit rating makes it appropriate for intermediate to final finishing passes where surface quality matters. It is specifically designed for use with the Line-Mate 30-A 268 Drum, making it a direct consumable replacement in that system. Applications span metal fabrication shops, maintenance and repair operations, and industrial production environments where consistent surface preparation is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e80-grit aluminum oxide abrasive for fine-grade surface finishing and blending\u003c\/li\u003e\n  \u003cli\u003eCloth backing provides durability and flexibility across irregular surfaces\u003c\/li\u003e\n  \u003cli\u003eInterleaf construction promotes even wear and consistent cut rate\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded center hole for secure drum arbor mounting\u003c\/li\u003e\n  \u003cli\u003eRated to 3,800 RPM maximum for safe high-speed operation\u003c\/li\u003e\n  \u003cli\u003eCompatible with aluminum, stainless steel, and carbon steel workpieces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the Line-Mate 30-A 268 Drum.

Power down and lock out the drum unit completely before mounting or removing the flap wheel. Verify the arbor thread engagement is secure before resuming operation, and confirm the equipment spindle speed does not exceed the 3,800 RPM rating of this wheel. Always wear appropriate PPE including eye protection and gloves when handling abrasive products and operating grinding equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 80\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Fine\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Aluminum Oxide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Cloth\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Hole Thread Size\u003c\/strong\u003e: 5\/8-11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum RPM\u003c\/strong\u003e: 3,800\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterleaf\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Stainless Steel, Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\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: WALTER SURFACE TECHNOLOGIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 07K442\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67912047001906,"sku":"07K442","price":169.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ce1ac5a03bffec9479e3baf5697362d6.jpg?v=1791225974","url":"https:\/\/voomisupply.com\/products\/walter-surface-technologies-07k442-flap-wheel-80-grit","provider":"Voomi Supply","version":"1.0","type":"link"}
