3M Green Corps Hookit Abrasive Disc 255U combines features for smooth, even sanding on tough surfaces. Grade 24 - 80 ceramic and aluminum oxide blend abrasive is resin bonded to durable E weight paper backing, with open coat construction that reduces loading even on fresh filler. These discs are ideal for shaping plastic filler and putty, paint removal and scratch refinement on bare metal.

A Tough Disc for Tough Surfaces
Built to hold up during the most demanding auto body sanding jobs, 3M™ Green Corps™ Hookit™ Abrasive Disc 255U is resin bonded for heat resistance. And our Hookit™ attachment system lets operators quickly change out discs during multi-step sanding processes.

Superior Dust Resistance
Open coat construction means that our abrasive grains are spaced so that dust and debris can collect in the spaces rather than loading the disc. Additionally, the open coat feature provides a more aggressive cut than a comparable closed coat abrasive of the same grade, for faster results. Several versions of this disc feature our 7- or 8-hole pattern that helps evacuate dust from the work surface, dramatically increasing disc life and maximizing cut-rate.

Blended Grain for Better Cut
The 3M™ Ceramic Abrasive Grain is a ceramic mineral designed using a 3M process to enhance toughness and hardness of the grain. For increased performance, 3M™ Green Corps™ Hookit™ 255U abrasive discs feature aluminum oxide blended with 3M™ Ceramic Abrasive Grain for one of the most durable, longest-lasting abrasives available. Perfect for moderate to heavy stock removal as well as sanding and finishing applications, ceramic abrasives are engineered to cut fast and handle intense heat and stress. Ceramic aluminum oxide blend surpasses aluminum oxide abrasives in cut-rate and durability, making this product an excellent choice for sanding metal, plastic, and fiberglass substrates, and finishing applications.

Our Hookit™ Attachment System
Hook-and-loop style 3M™ Hookit™ discs are ideal for work spaces where adhesive backed discs may become contaminated by dust, dirt, or flying debris. They are often used in applications where a 3M™ Stikit™ disc may be too aggressive, as Hookit™ discs tend to leave finer finishes than adhesive backed discs. Hookit™ sanding discs conveniently and firmly attach to a hook-and-loop backup disc pad (sold separately) on a random orbital sander, can be removed cleanly and easily, and be used again and again for the extent of the abrasive life.

Durable Through and Through
From grain to backing to bonding to disc pad attachment, our Green Corps™ Hookit™ Abrasive Disc 255U is built for long life – even for tough auto body sanding projects. Top quality sanding using fewer discs is just another way that auto body professionals can get the most from their operations.
