3M Hookit Paper Sheet 236U, P320 C-weight, 3 in x 4 in, 50/Carton

Features

Designed for use with a 3 x 4 inch orbital sander, the strong C-weight paper backing resists tearing and edgewear during aggressive sanding, and the sheet is resin-bonded for heat-resistance, further increasing life and cut. 3M™ Hookit™ Paper Sheet 236U also features an open coat and a load-resistant coating to enhance dust management and cut-rate.

A load-resistant coating allows the sheet to continue cutting even when sanding softwoods, paints, and other materials that would, otherwise, clog the surface of the sheet 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 sheet life.

Sanding products come in a variety of forms to fit various power tools and backup pads. Our 3M™ Hookit™ Sheet conveniently and firmly attaches to a 3 x 4 inch (75 x 100mm) 3M™ Hookit™ Pad (sold separately) on a 3 x 4 inch 3M™ Orbital Sander. Our Hookit™ sheets 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 sheet life (whereas adhesive-backed sheets 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.
