The 3M™ Interface Pad is a 1/2-inch thick, medium density foam pad that provides additional surface conformability when used with a 3M™ Hookit™ backup pad on a 3M™ Random Orbital Sander. The additional conformability helps when sanding critical surfaces with fine grade abrasives, after leveling and refining sanding steps are complete, but before final surface finishing steps.

  • Medium density foam provides additional flexibility on contours
  • Ideal for sanding curves, angles and contours
  • Applies effortlessly between Hookit™ discs and Hookit™ back-up pads for quick changeouts
  • May include Clean Sanding hole configuration to clear dust from the work surface, increasing disc life

  1. What is the 3M™ Hookit™ Interface Pad 28845 used for?

    The 3M™ Hookit™ Interface Pad 28845 is designed to be used with abrasive discs on random orbital sanders. It provides a cushioned interface between the sander and disc, which helps to reduce vibration, improve cut rate and increase abrasive life.

  2. Can the pad fit other sanding discs besides 3M ones?

    Yes, the 3M™ Hookit™ Interface Pad has a hook-and-loop backing that securely holds any compatible hook-and-loop sanding disc of equivalent size.

  3. How many pieces come in a case of this product?

    There are ten pads included in each case of the 3M™ Hookit™ Interface Pad 28845, each measuring three inches by four inches.

Conformability Protects Your Tools and Your Work Surface

When sanding rounds and profiles, the 3M™ Interface Pad provides additional conformability to protect your tools and work surface. It is placed between the backup pad and the abrasive disc or sheet, and helps operators reach internal angles.

The Clean Sanding Option – No Alignment Required

Some interface pads are designed to work with the 3M Clean Sanding system to maximize dust extraction. These pads must be used with a 3M™ Clean Sanding Backup Pad on a self-generated or central vacuum tool. The 3M™ Clean Sanding dust-management system evacuates dust from the work surface better than 5 or 6-hole products, dramatically increasing disc life and maximizing cut-rate. The Clean Sanding system provides dust extraction from the air surrounding the tool, as well as directly from the work surface. This reduces loading of the disc and adds life to the abrasive. Additionally, reducing dust in the air improves working conditions.

The 3M™ Clean Sanding Interface Pad is available for use with 5 inch Clean Sanding Disc Pads and discs or 3x4" Clean Sanding Pads and sheets. Both feature a unique multi-hole pattern designed to maximize dust evacuation, extending the abrasive's life, improving results and keeping the air clean as well. For maximum dust extraction when using 3M™ Clean Sanding Interface Pads, align the holes in the interface pad with the holes in the back up pad, when installing the interface pad. The unique, multi-hole design of 3M™ Clean Sanding Abrasive sanding discs do not require alignment on the backup pad or interface pad, further saving you time and hassle.

The 3M™ Hookit™ System

The Hookit™ attachment system is integrated to make abrasive changes quick and easy, enabling repeated use and reducing material consumption.

3M Science Optimizes Industrial Abrasives

3M pays attention to every detail of the abrasive process, from discs to tools to all the accessories in between. 3M™ Interface Pads are an excellent example of how 3M uses science to continually improve abrasive operations and help businesses operate faster, better and more efficiently. Engineered with quality foam construction, Hookit™ backing and the unique hole design on the Clean Sanding options, 3M™ Interface Pads are optimized for industrial abrasives.
