3M 7100033553 Quick Change Abrasive Disc 1.5 in Coarse Ao

Product Description

The 3M 7100033553 is a Standard Abrasives Quick Change Surface Conditioning RC Disc designed for surface prep work on flat stock, composites, and softer metals including aluminum. The disc uses aluminum oxide mineral on an open-web RC material that breaks down under medium pressure to continuously expose fresh abrasive fibers, maintaining consistent cut rate throughout the disc life. It is load-resistant, which reduces clogging when working through paint, corrosion, or soft metal swarf. At 1.5 inches in diameter and rated coarse grade, it fits applications where aggressive cleaning and light material removal are needed before coating or final finishing. Licensed trades and fabrication shops use this disc to combine cleaning and finishing into a single pass.

This disc is suited for blending, coating removal, surface finishing, and light deburring on flat surfaces. The open-web construction conforms to minor surface irregularities and reduces the risk of gouging the workpiece. It performs well on composites and soft metals such as aluminum where clogging is a common problem with conventional abrasive discs. The quick-change attachment system allows rapid disc swaps without tools, improving efficiency on production and service work where multiple discs are cycled through a session.

Key Features

• Aluminum oxide mineral on RC open-web material provides good initial and sustained cut rate
• Load-resistant construction resists clogging from paint, corrosion, and soft metal debris
• Open-web structure conforms to surface irregularities and minimizes gouging
• Suited for blending, coating removal, finishing, and light deburring on flat surfaces
• Quick-change mount allows fast, tool-free disc swaps to reduce downtime
• Coarse grade brown disc for general use and moderate-pressure applications

Compatibility

Designed for use with standard quick-change disc holders and right-angle die grinders or finishing tools that accept 1.5-inch quick-change abrasive discs.

Installation Notes

Ensure the backing pad or quick-change holder is rated for the disc diameter before mounting. Inspect the disc for tears or damage before each use and discard any disc that shows signs of delamination. Operators should wear appropriate eye and hand protection when using abrasive discs. Follow applicable shop safety protocols and tool manufacturer guidelines for maximum RPM ratings.
