Merit Abrasives 08834184291 Overlap Disc 100 Grit 1-1/4 in

Product Description

The MERIT ABRASIVES 08834184291 is a flexible slotted overlap disc designed for precision surface finishing in tight or contoured areas. Measuring 1.25 inches in diameter, this coated aluminum oxide disc runs at 100 grit, placing it in the fine grade range. The inward overlap disc design features two abrasive layers that provide consistent cutting action and extended service life compared to standard single-layer discs. The 8-32 eyelet size allows secure mandrel mounting. It is suited for use on metal, wood, and composite surfaces where controlled material removal and surface prep are required.

This overlap disc is used in applications where a small-diameter abrasive is needed to access recessed areas, narrow slots, or cylindrical bores. The flexible construction allows the disc to conform to irregular surfaces, making it a practical choice for deburring, blending, and light stock removal. Machinists, tool and die technicians, and metal fabrication professionals commonly use this disc type in die grinders or rotary tools during finishing and surface conditioning work.

Installation Notes

Installation is performed by threading the eyelet onto a compatible 8-32 mandrel and securing it in the collet of a die grinder or rotary tool. Ensure the tool is powered off and the collet is fully released before mounting or removing the disc. Wear appropriate eye protection and follow all applicable workplace safety guidelines when operating rotary abrasive tools. Do not exceed the rated speed for the disc or mandrel being used.
