It measures 4.5 inches in diameter with a 5\/8-11 threaded arbor hole for direct mounting on standard angle grinders. The disc uses zirconia alumina abrasive at 36 grit, placing it in the extra coarse grade range. This combination delivers fast stock removal and moderate heat resistance, making it a practical choice for weld blending, surface prep, and deburring work. The poly-cotton backing provides flexibility and durability through extended use. Licensed trades and fabrication shops rely on this disc type for heavy grinding tasks.\u003c\/p\u003e\u003cp\u003eThis flap disc is suited for grinding and surface conditioning on mild steel, carbon steel, and stainless steel. The Type 29 conical design angles the flaps for more aggressive contact with flat and contoured workpieces compared to a flat Type 27 disc. It is commonly used in metal fabrication shops, structural steel work, and pipeline maintenance where fast material removal at a consistent finish is required. The 5\/8-11 thread mount fits the majority of 4.5-inch angle grinders used in the field.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 29 conical geometry for aggressive grinding angle and increased stock removal\u003c\/li\u003e\n\u003cli\u003e36 grit extra coarse zirconia alumina abrasive for fast material removal\u003c\/li\u003e\n\u003cli\u003e4.5-inch diameter with 5\/8-11 threaded arbor hole fits standard angle grinders\u003c\/li\u003e\n\u003cli\u003eZirconia alumina abrasive offers self-sharpening properties and extended disc life on ferrous metals\u003c\/li\u003e\n\u003cli\u003ePoly-cotton backing adds flexibility for use on flat and contoured surfaces\u003c\/li\u003e\n\u003cli\u003eRated for steel and stainless steel applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 4.5-inch angle grinders fitted with a 5\/8-11 threaded spindle.

Confirm the grinder spindle thread is 5\/8-11 before mounting. Always verify the grinder RPM rating meets or exceeds the disc RPM rating before use. Wear appropriate eye, face, and hand protection per ANSI and applicable shop safety standards when operating angle grinders with abrasive discs.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Diameter\u003c\/strong\u003e: 4.5 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\u003eFlap Disc Type\u003c\/strong\u003e: Type 29\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrit\u003c\/strong\u003e: 36\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade\u003c\/strong\u003e: Extra Coarse\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Material\u003c\/strong\u003e: Zirconia Alumina\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAbrasive Type\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAttachment Type\u003c\/strong\u003e: Threaded Arbor Hole\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Material\u003c\/strong\u003e: Poly-Cotton\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisc Color\u003c\/strong\u003e: Blue\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steels, Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: PLMSC13121\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51710675124530,"sku":"PLMSC13121","price":140.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c6de9fd94a85f8abdf0bd1cbc4e502c6_e432333b-067a-4351-b9c2-10e29471069a.jpg?v=1788469397","url":"https:\/\/voomisupply.com\/products\/value-collection-plmsc13121-flap-disc-36-grit-type-29","provider":"Voomi Supply","version":"1.0","type":"link"}
