3M Hookit Clean Sanding Sheet 236U, P120 C-weight, 3 in x 4 in, Die M574, (50/Carton) Case of 500

• 3M Hookit sheets provide reliable attachment and are easy to change and reuse, maximizing sanding utility for the life of the sheet
• Open coat construction and load-resistant coating prevent premature loading of the disc surface to maximize cut and extend abrasive life
• Precise multi-hole pattern achieves superior dust extraction when used with a vacuum system
• Premium aluminum oxide mineral with a resin bond is durable, cuts fast, and performs well on many surfaces
• Strong, C-weight paper backing resists tearing and supports aggressive sanding with extra durability compared to lighter weight paper backings

3M Hookit Clean Sanding Sheet 236U offers superior dust control, aggressive cut, and long life on a premium aluminum oxide sheet with a durable edge and convenient 3M Hookit attachment. It features a proprietary multi-hole Clean Sanding pattern that evacuates dust better than traditional sheet products — dramatically increasing sheet life.

3M Hookit Clean Sanding Sheet 236U is well suited for high production sanding operations as well as general purpose applications.

Choose the 3M Hookit Clean Sanding Sheet 236U for blending and finishing on aluminum and carbon steel, and for woodworking applications such as heavy and medium stock removal and finishing on hardwoods, softwoods, and composites. This sheet also works well on primer, paint, sealers, topcoats, fiberglass, and plastics. Designed for use with a rectangular 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. This sheet also features an open coat and a load-resistant coating to enhance dust management and cut-rate.

To achieve maximum dust extraction, use this sheet with our 3M Clean Sanding Hookit Pad and our 3 x 4 inch (75 x 100mm) 3M Orbital Sander with vacuum (both sold separately).

Sandpaper cuts better and last longer when dust isn't loading the cutting surface of the abrasives. Reducing dust is easier than ever with 3M Clean Sanding products. The 3M proprietary multi-hole pattern on Clean Sanding products evacuates dust at a higher rate than traditional dust free patterns. The multi-hole pattern achieves an ideal balance between the abrasive surface and dust extraction holes to maximize cut and optimize the life of the product. This hole design doesn't even require alignment of holes with the pad, making sheet changes quick and simple. Suction via a vacuum system is drawn through the holes to collect dust from the air and workpiece, for improved working conditions, sheet performance, and overall productivity.

Our 3M Hookit Clean Sanding Sheet 236U also features a load-resistant coating that 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 disc pads. 3M Clean Sanding products come with a 3M Hookit attachment. A Hookit sheet conveniently and firmly attaches to a hook-and-loop backup pad (sold separately) on an orbital sander. 3M 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.

Reliable 3M Hookit Attachment

The 3M Hookit Clean Sanding Sheet 236U features the trusted 3M Hookit attachment system, making it easy to change and reuse sheets. This system maximizes sanding utility throughout the life of each sheet, ensuring consistent performance.

Designed for use with a rectangular orbital sander, the Hookit attachment firmly holds the 3 in x 4 in sheets in place. This setup supports quick sheet changes and repeated use, saving time and effort during sanding tasks.

Durable C-Weight Backing

This sanding sheet uses a strong C-weight paper backing that resists tearing and edgewear. The backing supports aggressive sanding, providing extra durability compared to lighter weight papers, which helps maintain sheet integrity during tough jobs.

With a resin bond for heat resistance, the 3M Hookit Clean Sanding Sheet 236U withstands demanding applications. Its backing and bonding extend the sheet’s life while maintaining a consistent cut on various surfaces.

Premium Aluminum Oxide Mineral

The 236U model contains premium aluminum oxide mineral, known for fast cutting and durability. This resin-bonded abrasive performs well on many surfaces, including aluminum, carbon steel, hardwoods, and composites.

Aluminum oxide self-fractures to expose fresh cutting edges, making it ideal for heavy and medium stock removal. It’s also suitable for sanding primer, paint, sealers, topcoats, fiberglass, and plastics.

Effective Dust Extraction Pattern

This sanding sheet features a precise multi-hole pattern designed for superior dust extraction. When used with a vacuum system, it dramatically improves dust removal, enhancing sheet life and sanding efficiency.

The open coat construction spaces abrasive grains apart, allowing dust to escape rather than clog the surface. This design helps maintain a high cut rate and reduces loading during sanding.

Convenient Pack Size Options

The 3M Hookit Clean Sanding Sheet 236U comes in a pack of 50 sheets per carton, with a case containing 500 sheets. This bulk packaging suits high production sanding operations and general purpose applications.

Each sheet measures 3 in x 4 in, fitting standard orbital sanders. The pack size and dimensions make it easy to stock up and keep sanding projects running smoothly without frequent reordering.
