3M 7000000691 Scotch-brite Exl Unitized Wheel 1.5 in

Product Description

The 3M 7000000691 is a Scotch-Brite EXL Unitized Wheel designed for deburring, smoothing, and surface finishing on metal alloys, plastics, and composites. The wheel measures 1.5 inches in diameter and uses silicon carbide as its abrasive mineral. Its soft, conformable construction keeps the abrasive in consistent contact with irregular or complex part geometries. Unitized wheels of this type are used by machinists, fabricators, and finishing technicians on bench grinders, die grinders, and automated robotic finishing systems. The wheel ships individually and weighs 0.01 pounds.

This wheel is suited for edge deburring, light surface blending, and pre-finishing operations on ferrous and non-ferrous metals as well as many plastics and composite materials. The conformable consistency makes it effective in both manual hand-tool applications and robotic or automated processing lines where consistent part contact pressure is critical. It is appropriate for job-shop fabrication, precision machining environments, and production finishing workflows where heat-sensitive materials require a low-heat abrasive process.

Key Features

• Silicon carbide abrasive construction for effective finishing on metals, plastics, and composites
• Unitized layered construction operates in both clockwise and counterclockwise directions
• Conformable consistency maintains abrasive contact on complex and irregular part shapes
• Resists smearing for cleaner finished surfaces with less secondary prep work
• Minimizes heat buildup, reducing thermal impact on heat-sensitive workpiece materials
• Wheel edge can be dressed for precise deburring and polishing profiles

Compatibility

Designed as an OEM-style replacement or standard consumable for bench grinders, die grinders, and robotic finishing spindles accepting 1.5-inch diameter unitized abrasive wheels.

Installation Notes

Installation should be performed by a qualified machinist or finishing technician familiar with abrasive wheel safety. Always power down and de-energize the tool before mounting or removing the wheel. Verify that the tool spindle speed rating meets or exceeds the rated maximum RPM of the wheel before operation. Inspect the wheel for damage before each use and never use a cracked or deformed unitized wheel.
