From the Manufacturer

3M™ Hookit™ Paper Disc 236U offers aggressive cut and long life on a premium aluminum oxide disc with a durable edge and convenient Hookit attachment. A go-to product in many industrial operations, this durable disc is well suited for high production sanding operations as well as general purpose applications on paint, primer, wood, metal, plastic, and composites, including fiberglass. Designed for use with a random orbital sander, the strong C-weight paper backing resists tearing and edgewear during aggressive sanding, and the disc is resin-bonded for heat-resistance, further increasing life and cut. These discs also feature an open coat and a load-resistant coating to enhance dust management and cut-rate.

A load-resistant coating allows the disc to continue cutting even when sanding softwoods, paints, and other materials that would, otherwise, clog the surface of the disc and hinder sanding ability. Loading is further reduced by an open coat, which means the abrasive grains are spaced slightly apart so that dust can escape rather than obstructing the cutting edge of the grains, thereby optimizing cut-rate and disc life.

Sanding discs come in a variety of forms to fit various power tools and disc pads. A 3M™ Hookit™ Disc conveniently and firmly attaches to a 3M™ Hookit™ Disc Pad (sold separately) on a random orbital sander. Hookit discs are quick and easy to change when switching from one grade to another, and can be reused again and again for the extent of the disc life (whereas adhesive-backed discs are typically discarded after one use because the adhesive backing will not re-adhere a second time).

Aluminum oxide is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut-rate, hardness, and strength, it is widely used in grinding applications in addition to sanding and finishing applications. Aluminum oxide is suitable for a wide variety of materials in both woodworking and metalworking, including ferrous alloys.

Product Description

3M Soft Interface Disc Pad is constructed of ½ inch soft density foam with a 3M Clean Sanding hole pattern to allow dust extraction and minimize loading during sanding. The soft foam construction enables the pad to conform to edges and contours, making it a good match for sensitive workpieces where gouging and marring is a top concern.

From the Manufacturer

The 3M&#8482 Clean Sanding Soft Interface Disc Pad 20278 is constructed of 1/2″ soft density foam with a 3M Clean Sanding hole pattern to add conformability to a 5″ Clean Sanding Hookit&#8482 backup pad &#40sold separately&#41. The soft interface disc pad provides a greater cushion and more conformability than does one with medium density foam. Use this pad to reduce edge cutting when the pad is tipped on edge and maintain closer contact with the edge while maximizing dust extraction. The pad contains a series of uniquely designed holes and channels which allow dust to be pulled through the holes and away from the sanding surface. This improves the work environment and prolongs disc life.

3M’s 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. Optimized with a self-generated vacuum sanding tool fitted with a Clean Sanding filter bag &#40sold separately&#41, Clean Sanding products allow the vacuum to suction dust from the air and off of the workpiece. This reduces loading of the disc and adds life to the abrasive. Additionally, reducing dust in the air improves working conditions. You can also pair Clean Sanding abrasives with Clean Sanding disc pads for use on a central-vacuum-ready sander.
