3M 7100192074 Hookit 216U Sanding Disc 5 Inch P400

Product Description

The 3M 7100192074 is a Hookit 216U coated abrasive sanding disc designed for finish sanding applications in woodworking, automotive refinishing, and light metalworking. The disc features a proprietary multi-hole pattern that evacuates dust more effectively than standard 5- or 6-hole disc designs, extending disc life and maintaining cut rate throughout use. Open coat construction and a load-resistant coating work together to resist clogging on resinous or soft materials. The aluminum oxide mineral delivers consistent, fast cutting across a broad range of surfaces. At P400 grit, this disc is suited for final finish passes and surface prep before coating or topcoat application.

This disc is intended for use with Hookit hook-and-loop backup pads on random orbital and orbital sanders used in production finishing environments. The multi-hole pattern pairs with dust extraction systems or vacuum-ready sanders to keep the work surface clean and reduce airborne particulate. The 5 inch diameter and P400 grit make it a common choice for automotive body finish work, cabinet finishing, and fine wood surface preparation. The Hookit attachment system allows fast disc changes and permits disc reuse, which is practical in high-volume finishing operations.

Installation Notes

This disc is installed and removed by hand using the Hookit hook-and-loop interface — no tools required. Confirm the backup pad diameter and hole pattern align with the disc before use. Always verify the sander RPM rating does not exceed the 10000 RPM disc rating before operation. Disconnect power to the tool before mounting or removing the disc.
