Measuring 4.5 inches in outside diameter and 4 inches in width, this wheel features a 5\/8-11 threaded center hole for secure mounting. It carries a coarse grade abrasive rating and is rated for a maximum of 3,800 RPM. The nonwoven construction delivers consistent scratch patterns and conforms to irregular or contoured surfaces without loading. Metalworking fabricators and finishing technicians install this wheel for aggressive material removal and surface prep on a range of ferrous and non-ferrous metals.\u003c\/p\u003e\n\u003cp\u003eThe 07M442 is suited for surface conditioning applications on aluminum, brass, copper, stainless steel, and other alloys. It is designed for use on fabrication shop equipment where a drum-style surface conditioning setup is required. Typical applications include deburring, blending, and light stock removal on flat or slightly curved workpieces. This wheel is well matched for production-level metalworking environments where consistent finish quality across multiple passes is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNonwoven aluminum oxide construction conforms to contoured surfaces without loading\u003c\/li\u003e\n  \u003cli\u003eCoarse grade abrasive for aggressive deburring and surface blending\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 threaded center hole for positive, secure drum mounting\u003c\/li\u003e\n  \u003cli\u003e3,800 RPM maximum rating for safe operation on compatible equipment\u003c\/li\u003e\n  \u003cli\u003eCompatible material applications include aluminum, brass, copper, stainless steel, and other alloys\u003c\/li\u003e\n  \u003cli\u003eNo interleaf design provides open structure and extended wheel life in metalworking applications\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 and Surface Conditioning Drum as specified by the manufacturer.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis wheel is installed by metalworking technicians onto compatible drum-style surface conditioning equipment. Before mounting or replacing the wheel, power down and disconnect the equipment from its power source. Verify that the spindle thread size matches the 5\/8-11 center hole before installation, and confirm operating speed does not exceed the 3,800 RPM maximum rating. Never exceed the rated RPM, and inspect the wheel for damage before each use.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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: Non-Woven\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Coarse\u003c\/li\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\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: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Brass, Copper, Other Alloy, Stainless 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: 07M442\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":67911329087794,"sku":"07M442","price":142.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1ba8d0dca7ad7639fd1a24834f6d78f2.jpg?v=1791209654","url":"https:\/\/voomisupply.com\/products\/walter-surface-technologies-07m442-flap-wheel-4-5x4-in-coarse","provider":"Voomi Supply","version":"1.0","type":"link"}
