Built around 3M Precision-Shaped Grain abrasive technology, this disc cuts faster and lasts longer than conventional aluminum oxide flap discs. At 4.5 inches in diameter and 80 grit, it targets weld leveling, light deburring, and surface preparation ahead of painting or coating. The poly-cotton backing promotes controlled, even wear under medium unit pressure, and individual flaps break down progressively to expose fresh mineral throughout the life of the disc.\u003c\/p\u003e\n\u003cp\u003eThis disc is suited for fabrication shops and field grinding operations working with mild steel and stainless steel. It performs well on weld seam removal, bead blending, and surface prep where gouge resistance and consistent finish quality matter. Stainless steel fabricators benefit from its reduced gouging tendency compared to fiber discs and bonded abrasive wheels. The T29 conical profile allows both flat and contoured surface contact, making it practical for a range of workpiece geometries encountered in structural, sheet metal, and pipe fabrication work. Minimum order quantity is 10 discs per unit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3M Precision-Shaped Grain delivers fast cut rate and extended disc life versus conventional abrasives\u003c\/li\u003e\n  \u003cli\u003eType 29 conical profile supports both flat and contoured surface grinding\u003c\/li\u003e\n  \u003cli\u003ePoly-cotton backing provides controlled, even wear under medium unit pressure\u003c\/li\u003e\n  \u003cli\u003eProgressive flap breakdown continuously exposes fresh abrasive mineral for consistent cut rate\u003c\/li\u003e\n  \u003cli\u003eLess gouging than fiber discs and bonded wheels, suitable for finish-sensitive stainless steel work\u003c\/li\u003e\n  \u003cli\u003eSuited for weld leveling, light deburring, and pre-paint surface preparation on mild and stainless steel\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard 4.5-inch right-angle grinders accepting T29 flap disc arbor configurations; appropriate for mild steel and stainless steel workpieces in medium-pressure grinding and surface preparation applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eMount and operate this disc using a right-angle grinder rated for the disc diameter and maximum RPM stamped on the disc. Inspect the disc for damage before each use and do not use if flaps are torn or the hub is cracked. Always wear appropriate PPE including a face shield and grinding gloves.
