3M Hookit Clean Sanding Sheet 236U, P320 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 convenience supports efficient sanding workflows, especially when working with the case of 500 sheets.

Durable C-Weight Backing

This sanding sheet uses a strong C-weight paper backing that resists tearing and edgewear during aggressive sanding. The backing provides extra durability compared to lighter paper backings, supporting tough sanding jobs.

With the 3M Hookit Clean Sanding Sheet 236U, you get a product that stands up to heavy use, perfect for high production sanding operations. The backing helps maintain sheet integrity over time, even with the 50 sheets per carton format.

Premium Aluminum Oxide Mineral

The 3M Hookit Clean Sanding Sheet 236U uses premium aluminum oxide mineral with a resin bond. This combination cuts fast and performs well on many surfaces, including aluminum, carbon steel, hardwoods, and composites.

Aluminum oxide is known for its toughness and long life. It self-fractures to expose fresh cutting edges, making it ideal for both woodworking and metalworking applications covered by this P320 grade sanding sheet.

Effective Dust Extraction Pattern

This sanding sheet features a precise multi-hole pattern designed to achieve superior dust extraction when used with a vacuum system. The open coat construction and load-resistant coating prevent premature loading of the disc surface.

Using the 3 in x 4 in 3M Hookit Clean Sanding Sheet 236U with a compatible vacuum system improves working conditions and extends abrasive life. The multi-hole design also simplifies sheet changes without needing hole alignment.

Convenient Pack Size Format

The product comes in a case of 500 sheets, with 50 sheets per carton, making it suitable for large-scale sanding projects. This pack size ensures you have plenty of sheets on hand for continuous work without frequent reordering.

Each sheet measures 3 in x 4 in, fitting standard orbital sanders. The die M574 format supports compatibility with various sanding tools, making this pack a practical choice for both general purpose and high production sanding.
