It features a 5\/8-11 female thread connection and is rated for a maximum speed of 6,600 RPM. The medium-density construction provides consistent disc support across the working surface. This type of backing pad is used in metal fabrication, surface preparation, and finishing work, and is typically installed by machinists, fabricators, and trades professionals working with angle grinders or disc sanders.\u003c\/p\u003e\n\u003cp\u003eThis backing pad is suited for applications requiring a secure disc attachment in medium-duty grinding and surface finishing scenarios. The locking nut interface keeps the abrasive disc firmly seated during operation, reducing the risk of disc slippage at speed. It is appropriate for use in shop environments, on-site metal work, and general surface prep tasks where a 5\/8-11 threaded spindle is present.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLocking nut design secures abrasive disc firmly to the spindle\u003c\/li\u003e\n  \u003cli\u003e5\/8-11 female thread fits standard angle grinder spindles\u003c\/li\u003e\n  \u003cli\u003eRated to 6,600 maximum RPM for safe high-speed operation\u003c\/li\u003e\n  \u003cli\u003eMedium density backing provides uniform disc support and contact\u003c\/li\u003e\n  \u003cli\u003eSold individually — package quantity of 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or spare backing pad for angle grinders and disc sanders equipped with a 5\/8-11 threaded spindle.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified operator with the grinder powered off and unplugged before attaching or removing the backing pad.
