Merit Abrasives 08834184042 Overlap Disc 80 Grit 1-3/4 in

Product Description

The MERIT ABRASIVES 08834184042 is a flexible slotted overlap disc engineered for coated abrasive applications requiring controlled material removal and surface finishing. Built with aluminum oxide abrasive across two overlapping layers, it delivers consistent cutting action at 80 grit, a medium-grade designation suited for moderate stock removal and surface blending. The disc measures 1-3/4 inches in diameter and features an inward overlap design with an 8-32 eyelet for secure mandrel mounting. Weighing 0.5 pounds per unit, it is sized for handheld rotary tool work in tight or contoured areas. Machinists, toolroom technicians, and maintenance trades install this type of disc for precision deburring and surface prep tasks.

This disc is well suited to deburring, light grinding, and surface conditioning work on metal, composite, and similar materials. The flexible construction allows the disc to conform to contoured or irregular surfaces, making it practical in applications where rigid abrasive tooling would lose contact. Typical use cases include cleaning weld zones, prepping fastener seats, and blending machined surfaces in confined workspaces. The 1-3/4 inch diameter fits standard small-diameter mandrels used in die grinders and rotary tools.

Key Features

• 80 grit aluminum oxide abrasive for medium-grade stock removal and surface blending
• Flexible disc construction conforms to contoured and irregular surfaces
• Inward overlap disc design with two abrasive layers for extended cutting life
• 1-3/4 inch diameter sized for die grinders and rotary tool mandrels
• 8-32 eyelet provides positive mandrel engagement and secure mounting

Compatibility

Designed as an OEM-style replacement or standard fitment for small-diameter mandrel-mounted abrasive disc applications in die grinders and rotary tools accepting 1-3/4 inch flexible overlap discs with an 8-32 eyelet.

Installation Notes

Installation is typically performed by machinists, toolroom technicians, or maintenance tradespeople using a compatible threaded mandrel. Ensure the rotary tool or die grinder is fully powered down and disconnected from its power source before mounting or removing the disc. Thread the eyelet onto the mandrel finger-tight and verify the disc seats flat before operating. Always confirm the tool RPM rating does not exceed the disc rating before use.
