3M 7000121840 | 840039 Standard Abrasives 3/4" Diameter Very Fine Aluminum Oxide Quick Change Surface Conditioning GP Disc

The Standard Abrasives Quick change surface conditioning GP disc saves time preparing workpieces for final finishes and coatings by performing one-step prep work. This multi-purpose, resin-reinforced disc works with all types of metal and is load-resistant, making it a good choice for aluminum and other soft metals. It offers reliable results on flat surfaces and some edgework.

Featuring a more compact structure of non-woven fibers than buff & blend products, the Standard Abrasives Quick change surface conditioning GP disc is engineered to provide a consistent cut-rate while producing a uniform finish. Constructed of resin-reinforced non-woven fibers, this disc resists loading and minimizes under-cutting or gouging of the workpiece.

Standard Abrasives GP surface conditioning discs are made of a tough but flexible nylon mesh that conforms to irregularities on the workpiece. A woven fabric (scrim) embedded in the nylon structure provides additional strength and durability. This helps extend the life of the disc and allows for prolonged use on ferrous materials or steel.

Choose the Standard Abrasives Surface conditioning GP disc for use on all metal types to perform:

• Deburring: Removing large and micro burrs, edge radiusing, removing die cast flashings
• Blending: Removing mill marks, tool marks and mismatches; reducing uneven edges between adjoining surfaces, reorienting surface scratch patterns, creating a smooth transition from one surface profile to another
• Cleaning: Removing coatings, gaskets and surface discolorations from welds or other work surfaces

Surface conditioning products have a non-woven construction in which fiber strands, resin, and abrasive mineral form a thick, open web or mesh. The spring-like nature of the fibers responds to the part and effectively removes unwanted burrs, soils and contaminants while maintaining the geometry of the workpiece, which in turn reduces rework and boosts productivity. Gaps in the web allow heat and swarf to escape, prolonging the performance of the abrasive. Fibers in the web continually break down with use to reveal fresh mineral for exceptional consistency, increased cut performance and extended service life.

The disc fibers are overlaid with aluminum oxide abrasive. Aluminum oxide discs are a good match for operators who desire an all-purpose versatility and economy. The mineral cuts fast while blending and deburring and can be used for applications on ferrous and non-ferrous metals and composites.

Quick change discs allow tool-free swap outs, maintain secure attachment at high speeds, and save operators time when switching discs between grades or applications. Easy fastening and swapping of discs enhances tool efficiency and worker productivity. The TP system features a snap-on/snap-off nylon fastening hub. TR discs have a nylon threaded male hub that easily threads onto TR or 3M Roloc type holder pads with a turn of the wrist, and the TS system has a metal hub that fastens to its holder pad with a simple twist.

Standard Abrasives Quick change GP discs are available with TP, TR and TS attachments in disc diameters up to 4". Discs with 4-1/2" to 7" diameters have a TS 5/8-11 threaded hub that easily mounts to a TS 5/8-11 holder pad. 3M recommend using the discs together with a Standard Abrasives quick change Holder Pad to ensure optimal disc performance and to ensure that pressure is applied evenly all the way to the edge of the disc.

The standard abrasives brand has supplied quality abrasives to the metalworking industry for over 50 years. Customers rely on the broad offering of high performance products including coated, bonded, and non-woven abrasive lines.
