It accepts a left-hand 3\/8-24 threaded spindle and mounts via a 1\/4-inch shank for secure chuck engagement. Rated to 20,000 RPM, it is suited for high-speed surface preparation, grinding, and finishing operations. The medium-density construction provides consistent backing support across the abrasive disc face, helping maintain contact uniformity during use. It is compatible with the Quick-Lok quick-change system, allowing fast disc swaps without additional tooling.\u003c\/p\u003e\u003cp\u003eThis backing pad is intended for use in metalworking, fabrication, and maintenance environments where quick-change abrasive disc systems are standard. Typical applications include weld dressing, surface blending, rust removal, and paint stripping on metal substrates. It is sized for handheld rotary and die grinder platforms used by machinists, maintenance technicians, and fabricators in both shop and field settings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eQuick-Lok quick-change compatibility for fast, tool-free disc swaps\u003c\/li\u003e\n\u003cli\u003eLeft-hand 3\/8-24 thread matches standard rotary spindle configurations\u003c\/li\u003e\n\u003cli\u003e1\/4-inch shank diameter for secure chuck or collet mounting\u003c\/li\u003e\n\u003cli\u003e20,000 RPM maximum speed rating suits high-speed die grinder applications\u003c\/li\u003e\n\u003cli\u003eMedium-density pad construction supports uniform disc contact across the work surface\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with Quick-Lok quick-change abrasive disc systems.
