3M 7100066678 Cubitron Ii 732U Sanding Disc 5 in 180 Grit

Product Description

The 3M 7100066678 is a coated abrasive sanding disc in the Cubitron II 732U series, featuring 3M Precision Shaped Grain technology designed for aggressive stock removal on a wide range of substrates. The triangular ceramic mineral geometry slices through material rather than plowing or gouging like conventional abrasive grains, resulting in faster cut rates and significantly extended disc life. At 180 grit, this 5-inch disc is suited for fine stock removal and surface prep work where a balance of cut rate and finish quality is needed. The hook-and-loop backing allows fast disc changes on compatible random orbital and orbital sanders.

This disc is intended for professional surface preparation applications including metalworking, woodworking, automotive bodywork, and composite finishing. The 5-inch diameter and 180 grit make it a practical choice for finish sanding and light material removal passes. A precision multi-hole pattern integrated into the disc face supports active dust extraction systems, keeping the work surface cleaner and extending disc life by reducing loading. It is suited for use in production environments and field service situations where downtime for disc changes and cleanup needs to be minimized.

Key Features

• 3M Precision Shaped Grain technology cuts up to 2x faster than conventional abrasives
• Disc life up to 4x longer than conventional abrasive discs
• Triangular ceramic mineral geometry slices substrate rather than gouging for a cleaner cut
• Hook-and-loop attachment system enables fast, tool-free disc changes
• Precision multi-hole pattern supports superior dust extraction and reduces disc loading
• Suitable for a wide variety of substrates focused on stock removal applications

Compatibility

Designed for use with 5-inch hook-and-loop random orbital and orbital sanders that accept multi-hole dust extraction discs. Verify that the sander hole pattern aligns with the disc hole pattern before use.

Installation Notes

Installation of this disc requires a compatible 5-inch hook-and-loop sanding pad. Ensure the sander is powered off and unplugged before attaching or removing the disc. Press the disc firmly onto the pad to ensure full hook-and-loop engagement before operation. Do not use this disc on a sander exceeding the disc speed rating.
