3M 7100077620 Hookit 360L Disc 6 Inch P220 Grit

Product Description

The 3M 7100077620 is a Hookit 360L coated abrasive sanding disc designed for high-efficiency material removal with superior dust evacuation. The disc measures 6 inches in diameter and carries a P220 grit rating using aluminum oxide abrasive grain. A precision multi-hole pattern evacuates dust more effectively than standard 5- or 6-hole disc designs, which directly extends disc life and maintains cut rate over the life of the disc. The durable film backing is tear-resistant and delivers a close-tolerance, consistent finish. This disc is rated to 12000 RPM and is used by finishing tradespeople, woodworkers, and surface prep technicians.

The 7100077620 is suited for finish sanding applications where dust control and surface consistency are critical. The open-coat, load-resistant construction prevents clogging, making it well-suited for work on wood, composites, and similar substrates in residential and light commercial environments. The Hookit attachment system allows fast disc changes without requiring hole alignment to the backing pad, reducing downtime between discs during high-volume work.

Key Features

• Precision multi-hole pattern provides excellent dust extraction without requiring hole alignment to the pad
• Open-coat, load-resistant abrasive coating prevents clogging and extends disc life
• Aluminum oxide grain cuts faster and lasts longer than traditional garnet abrasives
• Tear-resistant film backing delivers a close-tolerance, consistent surface finish
• Hookit hook-and-loop attachment allows fast, easy disc changes and disc reuse
• Rated to 12000 RPM for use with compatible random orbital and disc sanders

Compatibility

Designed for use with Hookit-compatible random orbital and disc sanding pads. No hole alignment to the backing pad is required due to the precision multi-hole pattern design.

Installation Notes

Ensure the sanding tool is powered off and unplugged before attaching or removing the disc. Press the disc firmly onto the Hookit backing pad to ensure full hook-and-loop engagement before operating. Do not exceed the rated 12000 RPM speed. Inspect the disc for tears or loading before each use and replace if damaged or glazed.
