Product Description
The MERIT ABRASIVES 69957399757 is a quick-change coated abrasive disc designed for use with Power-Lock Type 1 attachment systems. At 1 inch in diameter and rated for a maximum of 40,000 RPM, this disc uses 150-grit aluminum oxide abrasive on a rigid polyester backing. The Very Fine grade makes it suited for finish grinding, light deburring, and surface prep on metal and similar substrates. It is sold individually with a minimum order quantity of 100 units, making it a shop-consumable item stocked in bulk by fabrication and maintenance operations.
This disc is used in applications requiring controlled material removal at high speed in tight or confined areas. The 1-inch diameter suits handheld rotary tools and pneumatic die grinders used in fabrication shops, maintenance facilities, and field repair work. The aluminum oxide abrasive and rigid polyester backing provide consistent cut on ferrous metals, and the brown coated surface indicates the Series R766 construction. Technicians and fabricators performing weld cleanup, edge blending, or surface conditioning work are the primary installers.
